Flock of bird book reviews

Flock of bird books arrives this spring: Peterson, Heinrich, Kroodsma, Gilbert and Tallamy

Published April 5, 2020, in the Wyoming Tribune Eagle, “Flock of bird books arrives this spring.”

By Barb Gorges

            Spring is when Houghton Mifflin Harcourt likes to send out bird books to review—completely forgetting that as spring migration gets going, birders have less time to read. Maybe we’ll have more time to read this year. Luckily, birding in Wyoming, without Audubon field trips, is a solitary experience perfect for ensuring huge social distances.

            I’ve suggested that we all get social sharing our bird sightings on the Cheyenne-High Plains Audubon Society group Facebook page and through the Wyobirds Google Group. By posting sightings on eBird.org, everyone can “Explore” each other’s Laramie County bird sightings.

Peterson Field Guide to Birds of North America, Roger Tory Peterson (and contributions from others), 2020, Houghton Mifflin Harcourt, 505 pages, $29.99.

This latest edition of the classic field guides follows the 2008 edition, the first to combine Peterson’s eastern and western guides in one book. And now the birds of Hawaii have been added.

            Peterson died in 1996 so additional paintings, range map editing, etc. are the work of stellar artists and ornithologists. Bird names are updated, now showing the four species of scrub-jays, except that I heard last month it was decided to drop the “scrub” from their names.

            But, to be a birder, one must regularly invest in the most up-to-date field guide.

White Feathers, The Nesting Lives of Tree Swallows, Bernd Heinrich, 2020, Houghton Mifflin Harcourt, 232 pages, $27.

            If anyone can make eight springs of excruciatingly detailed observations interesting, Bernd Heinrich can. He wanted to know what purpose is served by tree swallows adding white feathers to their nests.

            Every spring, hour after hour, he observed the comings and goings of pairs using his nest box and noted when they brought in white feathers to line (insulate?) and cover (hiding eggs from predators?) the nest inside the box.

            Or, the white feathers might only advertise that a nesting cavity is taken. 

Birdsong for the Curious Naturalist, Your Guide to Listening, Donald Kroodsma, 2020, Houghton Mifflin Harcourt, 198 pages, $27.

            Here’s where you can find out what a tree swallow sounds like when it starts singing an hour before sunrise.

            In fact, you can skip this book and learn a lot by going to the associated free website, www.BirdsongForTheCurious.com. There are multiple songs each of most songbird species, as well as ideas for collecting your own data.

            The book has chapters explaining topics such as: “Why and How Birds Sing,” How a Bird Gets Its Song” and “How Songs Change over Space and Time.”

Unflappable, Suzie Gilbert, 2020, https://www.suziegilbert.com/.

            I read the first chapter for free online and I think it will be a very entertaining novel. Here’s the synopsis: “Wildlife rehabber Luna and Bald Eagle Mars are on a 2,300-mile road trip with her soon-to-be-ex-husband and authorities hot on their heels. What could possibly go wrong?”

Nature’s Best Hope, A New Approach to Conservation That Starts in Your Yard, Douglas W. Tallamy, 2019, Timber Press, 255 pages, $29.95.      

            Tallamy first wrote “Bringing Nature Home” in 2007 where, as a professor who studies insects and ecology, he explains that it is important for all of us to plant native plants to benefit native wildlife.

            Thirteen years later, Tallamy can cite a lot more research making his point: native plants support native insects which support other native wildlife (and support us). For instance, almost all songbird species, even if they are seed eaters the rest of the year, need to feed their young prodigious amounts of caterpillars plus other insects.

            These caterpillars of native butterflies and moths can’t eat just any old plant. They must chew on the leaves of the plants they evolved with—other leaves are inedible. Good news: rarely does the associated plant allow itself to be decimated.

            Native bees, except for some generalists, also have a nearly one on one relationship with the native nectar and pollen-producing plants they’ve evolved with. You may see bees working flowers of introduced plants, but chances are they are the introduced European honeybees.

            What’s a concerned backyard naturalist to do? Become part of Tallamy’s army of gardeners converting yards and wasted spaces of America into Homegrown National Park, http://www.bringingnaturehome.net/. A link there will take you to the National Wildlife Federation’s Native Plant Finder which lists our local natives based on our zipcodes.

            It’s not necessary to vanquish every introduced plant, but we must add more natives. The best way is by replacing turf. Here in Cheyenne, the Board of Public Utilities is encouraging us to save water by replacing water-thirsty bluegrass with water-smart plantings. Plants native to our arid region (12-15 inches of precipitation annually) fit the bill perfectly—and they aid our native pollinators at the same time.

            In next Sunday’s Cheyenne Garden Gossip column, I will discuss exactly how to do that here.

“Cheyenne Birds” available online and in Laramie

Pete Arnold’s and my book, “Cheyenne Birds by the Month, 104 Species of Southeastern Wyoming’s Resident and Visiting Birds,” is now available in Laramie at the University of Wyoming University Store.

                For those of you neither in Laramie nor Cheyenne, you can find it at the UW University Store’s uwyostore.com website: https://www.uwyostore.com/search_index_results.asp?search_text=Cheyenne+Birds&pageaction=redirect.

                And if you are in Cheyenne, there are copies available at the Cheyenne Botanic Gardens, Cheyenne Depot Museum, Cheyenne Pet Clinic, PBR Printing, Riverbend Nursery and the Wyoming State Museum.

                If you know of a store that would like to carry the book, have them contact me. The season for warmer birding is approaching and we’ve heard that readers who profess to be non-birders think of this as a field guide! It’s two-thirds Pete’s great photos and one-third text.

Bird and wildlife books for winter reading & gift giving

2018-12How to be a Good CreatureTry these bird and wildlife books for winter reading and gift giving

This column was also posted at Wyoming Network News: https://www.wyomingnetworknews.com/try-these-bird-and-wildlife-books-for-winter-reading-and-gift-giving. It appeared Dec. 16, 2018, in the Wyoming Tribune Eagle.

By Barb Gorges

Several books published this year about birds and other animals I recommend to you as fine winter reading, or gift giving.

The first, “How to be a Good Creature, A Memoir in Thirteen Animals” is a memoir by Sy Montgomery, a naturalist who has written many children’s as well as adult books about animals.

Montgomery has been around the world for her research. Some of the animals she met on her travels and the animals she and her husband have shared their New Hampshire home with have taught her important life lessons: dog, emu, hog, tarantula, weasel, octopus.

This might make a good read-aloud with perceptive middle-school and older children.

2018-12 Warblers and Woodpeckers“Warblers & Woodpeckers, A Father-Son Big Year of Birding” by Sneed B. Collard III was a great read-aloud. For two weeks every evening I read it to my husband, Mark, while he washed the dishes–a long-standing family tradition.

Like Montgomery, Collard is a naturalist and author, though normally he writes specifically and prolifically for children. He lives in western Montana.

When his son is turning 13, Collard realizes he has limited time to spend with him before his son gets too busy. Birdwatching becomes a common interest, though his son is much more proficient. They decide to do a big year, to count as many bird species as possible, working around Collard’s speaking schedule and taking friends up on their invitations to visit.

There are many humorous moments and serious realizations, life birds and nemesis birds, and a little snow and much sunshine. Mark plans to pass the book on to our younger son who ordered it for him for his birthday.

2018-12Wild MigrationsTwo Wyoming wildlife biologists, Matthew Kauffman and Bill Rudd, who have spoken at Cheyenne Audubon meetings on the subject, are part of the group that put together “Wild Migrations, Atlas of Wyoming’s Ungulates.” I ordered a copy sight unseen.

We know that many bird species migrate, but Wyoming is just now getting a handle on and publicizing the migrations of elk, moose, deer, antelope, bighorn sheep, mountain goat and bison, thanks to improved, cheaper tracking technology.

Each two-page spread in this over-sized book is an essay delving into an aspect of ungulates with easy-to-understand maps and graphs. For example, we learn Wyoming’s elk feed grounds were first used in the 1930s to keep elk from raiding farmers’ haystacks and later to keep elk from infecting cattle with brucellosis.

Then we learn that fed elk don’t spend as much time grazing on summer range as unfed elk, missing out on high-quality forage 22 to 30 days a year. Shortening the artificial feeding season in spring might encourage fed elk to migrate sooner, get better forage, and save the Wyoming Game and Fish Department money.

This compendium of research can aid biologists, land managers and land owners in smarter wildlife management. At the same time, it is very readable for the wildlife enthusiast. Don’t miss the foreword by novelist Annie Proulx.

2018-12 Guide to Western Reptiles and AmphibiansThanks, Houghton Mifflin Harcourt, for sending me a copy of the newly revised “Peterson Field Guide to Western Reptiles & Amphibians” by Robert C. Stebbins and Samuel M. McGinnis to review. I now know that what friends and I nearly stepped on while hiking last summer was a prairie rattlesnake, one of 12 kinds of rattlers found in the west.

There are 40-plus Peterson field guides for a variety of nature topics, all stemming from Roger Tory Peterson’s 1934 guide to the birds of eastern North America. I visited the Roger Tory Peterson Institute in Jamestown, New York, this fall and saw his original art work.

The reptile and amphibian guide first came out in 1966, written and illustrated by the late Stebbins. In in its fourth edition, his color plates still offer quick comparisons between species. Photos now offer additional details and there are updated range maps and descriptions of species life cycles and habitats. It would be interesting to compare the maps in the 1966 edition with the new edition since so many species, especially amphibians, have lost ground.

CheyBirdsbyMonth_FC_onlyI would be doing local photographer Pete Arnold a disservice if I didn’t remind you that you can find our book, “Cheyenne Birds by the Month” at the Cheyenne Botanic Gardens, Wyoming State Museum, Cheyenne Depot Museum, Riverbend Nursery and PBR Printing. People tell us they are using Pete’s photos to identify local birds. I hope the experience encourages them to pick up a full-fledged bird guide someday by Peterson, Floyd, Sibley or Kaufman.

Condors in Wyoming

Condor visits Wyoming; next condor needs to find steel instead of lead

By Barb Gorges

Exciting news in the Wyoming birdwatching community: A California condor, North America’s largest raptor with 9.5-foot wingspan, was sighted July 7 west of Laramie perched on Medicine Bow Peak. The reporting birder was Nathan Pieplow. He is the author of the Peterson guide to bird sounds. Maybe he recorded it.

Wing tags printed with a big T2 declared this was a female condor hatched and raised in 2016 at the Portland, Oregon, zoo and released in March at the Vermilion Cliffs National Monument in northern Arizona.

Several people from the Laramie Audubon chapter climbed up to see the condor. Brian Waitkus got excellent photos.

Medicine Bow Peak, elevation 12,014 feet, is a popular destination for hikers who want a challenge including lightning and boulder fields. As many as a dozen hikers were congregating near the condor July 9. The condor didn’t mind people but was flushed by three dogs off leash, observed Murie Audubon president Zach Hutchinson.

2018-08Condor T2Brian Waitkus

T2 was outfitted with wing tags and transmitter by the Peregrine Fund before her release in Arizona in March 2018. Photo courtesy of Brian R. Waitkus.

T2 was one of many condors released into the wild by the Peregrine Fund working to re-establish the population of this officially endangered species. In 1982 there were only 22 birds left. Today there are 500, half flying free in Arizona, Utah, California and Baja Mexico. Some are now breeding in the wild. For more, read Condors in Canyon Country by Sophie A. H. Osborn and https://www.peregrinefund.org/.

The distance between the Arizona release site and the peak is only 440 miles as the condor flies, not difficult for a bird that can travel 200 miles a day. T2 was spotted earlier, on June 28, near Roosevelt, Utah.

The closest previous Wyoming condor sighting was 1998, in Utah at Flaming Gorge Reservoir, which spans the Utah-Wyoming line.

T2’s visit was brief. A Peregrine Fund researcher following the condor using telemetry later got the signal 30 miles away indicating the bird was not moving. By the time he arrived, the bird was dead. It’s been sent to U.S. Fish and Wildlife Service for autopsy. Foul play was not suspected.

Serendipitously, soon after the first news broke about T2, Chris Parish, director of global conservation for the Peregrine Fund, was about to drop his daughter off in Laramie. He offered to give a talk on condors sponsored by the Laramie Audubon Society and the University of Wyoming Biodiversity Institute.

In his presentation, Chris touched briefly on the history of restoring the condor population.

Condors are tough. They survived the large mammal extinction 10,000 years ago. However, they are slow to reproduce, only one chick every two years. At propagation centers, experts can get a pair to lay an extra egg to put in an incubator.

Condors live 50 to 60 years by avoiding predators and finding new habitat. A few are still being shot, despite condors being as harmless as turkey vultures, eating only carrion–already dead animals. They fly into powerlines and get hit by vehicles too.

The biggest problem for condors is poisoning from lead ammunition, Chris said. When a deer is shot, the bullet disintegrates into hundreds of fragments. Often, the fragments are in the gut pile, or offal, that hunters leave in the field. Offal is the condor’s main dish.

All those little lead fragments add up and eventually cause lead poisoning. Some of those lead fragments also find their way into game meat people eat. Researchers try to check the blood lead levels of all free-flying condors once a year and treat them if necessary before releasing them again.

Our national symbol, the bald eagle, also feeds at carcasses. In 1991 lead shot for waterfowl hunting was banned but upland animals—and birds like the eagle–are not protected.

Arizona Game and Fish Department a few years ago asked hunters on the Kaibab Plateau, where condors are released, to voluntarily use steel ammunition or to remove offal. They offered each participant two free boxes of steel ammunition. Participation is now at 87 percent. A similar program is nearly as successful in Utah. California has banned lead ammunition since 2008, said Chris.

The Peregrine Fund holds shooting trials and gives away steel ammunition for hunters to test. Chris, a lifelong hunter, spouts ballistic statistics with ease. The bottom line is that lead and steel ammunition of comparable quality are nearly the same cost. However, manufacturers need encouragement to offer more variety.

Chris also said that yes, steel ammunition takes a little practice for the hunter to become proficient with it, but practice is required any time a hunter switches to the same caliber ammunition made by a different manufacturer.

Steel bullets aren’t silver bullets for all wildlife problems. But maybe Wyoming can join the steel states. That way we’ll make it safer here for when more condors show up.

Burrowing owls materialize

Burrowing Owl by Greg Johnson

Greg Johnson took this photo of a Burrowing Owl June 16, 2018, on the Cheyenne – High Plains Audubon Society field trip around southeastern Wyoming.

“Burrowing owls materialize on southeast Wyoming grasslands,” published July 29, 2018 in the Wyoming Tribune Eagle and at Wyoming Network News, https://www.wyomingnetworknews.com/burrowing-owls-materialize-on-southeast-wyoming-grasslands.

Burrowing owls materialize on southeast Wyoming grasslands

.

By Barb Gorges

Burrowing owls were like avian unicorns for me until this spring. Mark, my husband, and I searched prairie dog towns in southeastern Wyoming to no avail.

It wasn’t always like that. Fifteen years ago there was a spot on the east edge of Cheyenne guaranteed to produce a sighting for the Cheyenne Audubon Big Day Bird Count. But the area around it got more and more built up.

I did some research through my subscription to Birds of North America, https://birdsna.org and discovered burrowing owls don’t require complete wilderness.

These owls are diurnal—they are active during the day, most active at dawn and dusk. However, when the males have young to feed, they hunt 24/7.

The eggs are laid in old animal burrows, primarily those of prairie dogs. Because prairie dogs live in colonies, the burrowing owls tend to appear in groups, too, though much smaller. Besides nesting burrows, they have roosting burrows for protection from predators. They stockpile prey in both kinds of burrows in anticipation of feeding young. One cache described in a Saskatchewan study had 210 meadow voles and two deer mice.

Western burrowing owls, from southwestern Canada to southwestern U.S., winter in Central and South America. However, there are year-round populations in parts of California, southernmost Arizona and New Mexico and western Texas and on south. But there is also a subspecies of the owl that lives in Florida and the Caribbean year-round. They excavate their own burrows.

Burrowing owls breed in the open, treeless grasslands. No one is sure why, but they like to line their nesting burrows with dung from livestock. They, along with their prairie dog neighbors, appreciate how grazing animals keep the grass short. It’s easier to see approaching predators.

The owls’ biggest natural nest predator is the badger. Both young and adults can scare predators away from their burrows by giving a call that imitates a rattlesnake’s rattle.

Short grass means it’s easier to catch prey by walking or hopping on the ground as well as flying. Burrowing owls also like being near agricultural fields.

The fields attract their primary prey species: grasshoppers, crickets, moths, beetles, and in addition to small mammals like mice and voles, shrews.

You would think these owls are ranchers’ and farmers’ best friends. However, in the Birds of North America’s human impacts list are wind turbines, barbed wire, vehicle collisions, pesticides and shooting. I’m surprised by shooting.

Since western burrowing owls can’t be blamed for making the holes in pastures (they only renovate and maintain burrows by kicking out dirt) I can only surmise that varmint hunters have bad eyesight and can’t tell an owl from a prairie dog. It could be an easy mistake: Owls are nearly the color and size of prairie dogs and have similar round heads. Except the owls stand on long skinny legs. From a distance the owls look like prairie dogs hovering over the burrow’s mound—and then if you watch long enough, they fly.

Burrowing owls have been in sharp decline since the 1960s despite laying 6 to 12 eggs per nest. The Burrowing Owl Conservation Network, http://burrowingowlconservation.org, reports the U.S. Fish and Wildlife Service lists them as “a Bird of Conservation Concern at the national level, in three USFWS regions, and in nine Bird Conservation Regions. At the state level, burrowing owls are listed as endangered in Minnesota, threatened in Colorado, and as a species of concern in Arizona, California, Florida, Montana, Oklahoma, Oregon, Utah, Washington, and Wyoming.”

In our state, Grant Frost, Wyoming Game and Fish Department wildlife biologist, said “(burrowing owls) are what we classify as a species of greatest conservation need (SGCN), but mostly due to a lack of information; their status is unknown.  That is why these surveys were started three years ago.  There are 15 surveys being done throughout the state in potential habitat…each survey route is done three times each year during set times to occur during each of the three nesting stages – pre-incubation, incubation/hatching, and nestling.”

When Grant said he could lead an Audubon field trip to see the owls and other prairie birds, 15 of us jumped at the chance.

As might be predicted from the BNA summary of the literature, the owls were in the middle of an agricultural setting of fields and pastures. We watched them hunt around a flock of sheep and enjoy the view from the tops of fence posts along an irrigation canal.

The first sightings of the morning were distant—hard to see even with a spotting scope. But as we departed for home, driving a little farther down the road, two burrowing owls appeared much closer and we all felt finally that we could say we’d seen them and not just flying brown smudges.

Keep birds safe

Published May 6, 2018 in the Wyoming Tribune Eagle, “Keep birds safe this time of year” and also at https://www.wyomingnetworknews.com/keep-birds-safe-this-time-of-year.

By Barb Gorges

It’s that time of year that we need to think about bird safety —migration and nesting season.

2018-05abcbirdtape

Bird Tape is available from the American Bird Conservancy. Photo courtesy ABC.

The peak of spring migration in Cheyenne is around mid-May. If you have a clean window that reflects sky, trees and other greenery, you’ll get a few avian visitors bumping into it. Consider applying translucent stickers to the outside of the window or Bird Tape from the American Bird Conservancy, https://abcbirds.org.

If a bird hits your window, make sure your cat is not out there picking it up. The bird may only be stunned. If necessary, put the bird somewhere safe and where it can fly off when it recovers.

How efficient is your outdoor lighting? In addition to wasting money, excessive light confuses birds that migrate at night. Cheyenne keeps getting brighter and brighter at night because people install lighting that shines up as well as down, especially at businesses with parking lots. It is also unhealthy for trees and other vegetation, not to mention people trying to get a good night’s sleep.

Do you have nest boxes? Get them cleaned out before new families move in. Once the birds move in or you find a nest elsewhere, do you know the proper protocol for observing it?

You might be interested in NestWatch, https://nestwatch.org/, a Cornell Lab of Ornithology citizen science program for reporting nesting success.

Their Nest Monitoring Manual says to avoid checking the nest in the morning when the birds are busy, or at dusk when predators are out. Wait until afternoon. Walk past the nest rather than up to it and back leaving a scent trail pointing predators straight to the nest. And avoid bird nests when the young are close to fledging—when they have most of their feathers. We don’t want them to get agitated and leave the nest prematurely.

Some birds are “flightier” than others. Typically, birds nesting alongside human activity—like the robins that built the nest on top of your porch light—are not going to abandon the nest if you come by. Rather, they will be attacking you. But a hawk in a more remote setting will not tolerate people. Back off and get out your spotting scope or your big camera lenses.

If your presence causes a young songbird to jump out of the nest, you can try putting it back in. NestWatch says to hold your hand or a light piece of fabric over the top of the nest until the young bird calms down so it doesn’t jump again. Often though, the parents will take care of young that leave the nest prematurely. Hopefully, there aren’t any loose cats waiting for a snack.

2018-05Henry-Barb Gorges

Loose cats and dogs should also be controlled on the prairie between April and July, and mowing avoided. That is because we have ground-nesting birds here on the edge of the Great Plains such as western meadowlark, horned lark and sometimes the ferruginous hawk.

There will always be young birds that run into trouble, either natural or human-aided. Every wild animal eventually ends up being somebody else’s dinner. But if you decide to help an injured animal, be sure the animal won’t injure you. For instance, black-crowned night-herons will try to stab your eyes. It is also illegal to possess wild animals without a permit so call a licensed wildlife rehabilitator like the Cheyenne Pet Clinic, 307-635-4121, or the Wyoming Game and Fish Department, 307-777-4600.

Avoid treating your landscape with pesticides. The insect pest dying from toxic chemicals you spread could poison the bird that eats it. Instead, think of pest species as bird food. Or at least check with the University of Wyoming Extension office, 307-633-4383, for other ways to protect your lawn and vegetables.

Are you still feeding birds? We take our seed feeders down in the summer because otherwise the heat and moisture make dangerous stuff grow in them if you don’t clean them every few days. Most seed-eating birds are looking for insects to feed their young anyway. Keep your birdbaths clean too.

 

2018-05hummingbirds-Sandia Crest-Barb Gorges

Hummingbirds fill up at a feeder on Sandia Crest, New Mexico, in mid-July. Photo by Barb Gorges.

However, we put up our hummingbird feeder when we see the first fall migrants show up in our yard mid-July, though they prefer my red beebalm and other bright tubular flowers. At higher elevations outside Cheyenne hummers might spend the summer.

Make sure your hummingbird feeder has bright red on it. Don’t add red dye to the nectar though. The only formula that is good for hummingbirds is one part white sugar to four parts water boiled together. Don’t substitute any other sweeteners as they will harm the birds. If the nectar in the feeder gets cloudy after a few days, replace it with a fresh batch.

And finally, think about planting for birds. Check out the Habitat Hero information at http://rockies.audubon.org/programs/habitat-hero-education.

Enjoy the bird-full season!

Book reviews: Heinrich, Walden, bird i.d.

2018-04booksHeinrich_Naturalist-loEnjoy reading nature writing in three styles: essays, trail guide and guide to field guides

Also published at https://www.wyomingnetworknews.com/houghton-mifflin-harcourt-releasing-three-new-books.

By Barb Gorges

Houghton Mifflin Harcourt has three very different new nature books out this spring: a compilation of nature essays; a cross between trail, travel, nature and history guides; and a guide to using field guides.

A Naturalist at Large, The Best Essays of Bernd Heinrich, 2018, $26, 285 pages.

I am a fan of this man who finds so many questions to ask and then looks for the answers, even if it means climbing a tree and waiting hours to see where the ravens come back from, or spending hours watching a dung beetle make its ball.

You’ll recognize Bernd Heinrich’s topics of interest if you’ve read his other books including “Mind of the Raven,” “Racing the Antelope” and “Life Everlasting.”

The essays in this new collection were published in various magazines, mostly in recent issues of Natural History Magazine. So, the book title also means the older Heinrich gets, the better his writing. I agree. If his subjects appeal to you, soil, plants, trees, insects, bees, birds, mammals and how living things cope with the universe, you’ll enjoy this book.

I especially liked his investigation of the mechanics of how yellow iris instantly pop from bud to bloom.

2018-04booksThorson_GuideWalden_loThe Guide to Walden Pond, An Exploration of the History, Nature, Landscape, and Literature of One of America’s Most Iconic Places, Robert M. Thorson, 2018, $17, 250 pages, full color.

This book won’t mean much if you aren’t familiar with Henry David Thoreau, essayist, poet, philosopher, abolitionist, naturalist, tax resister, development critic, surveyor, and historian. Or his two-year experiment begun in 1845 living in a tiny, bedroom-sized house he built himself at Walden Pond, outside Concord, Massachusetts. You may want to first find a copy of his book, “Walden.”

Thoreau’s fame helped the state set aside 335 acres as the Walden Pond State Reservation (see https://www.walden.org). And he has inspired many conservationists with words such as, “In Wildness is the preservation of the World.”

Robert Thorson sets up his book as a trail guide and while taking a Thoreau-styled amble around the pond the reader gets a mix of history, natural history, biography and lots of beautiful photography.

2018-04BooksHowell_12STEPS_cvr_choice_loPeterson Guide to Bird Identification—in 12 Steps, Steve N.G. Howell and Brian Sullivan, 2018, $18 152 pages, full-color.

This is a small book full of well-illustrated information that should be at the beginning of every bird field guide.

The intended audience is everyone, the authors say, “We include some things that may be challenging for beginning birders, and others that may seem too basic for those more advanced, but this is intentional.” And that’s why you’ll want your own copy to study over and over.

Step 1 – Make sure you are looking at a bird. What kind? Duck, hawk, songbird?

Steps 2, 3, 4 – Where are you geographically, habitat-wise and seasonally? Despite some birds getting spectacularly lost (and becoming the rarities birders dream of), you can assume a species of bird will show up when and where field guides say it will.

Step 5 and 6 – Is the lighting good enough and the bird close enough to identify?

Step 7 and 8 – Is the bird behaving as its presumed species does? What does it sound like? Getting a handle on birdsong will make you a terrific birder.

Step 9 – Structure–size and shape–makes an easy identifier for birds you already know. Think about those plump robins in your yard. But I would argue it is difficult to use on birds you aren’t familiar with.

Step 10 – Finally, plumage! What color feathers?

Step 11 – Be aware of plumage variations.

Step 12 – Take notes—and photos.

Howell and Sullivan’s book makes a good introduction or review as we fly into spring migration. And you can fit in reading it between field trips.

Raptors popular; new book celebrates them

Raptors are popular birds; new book celebrates them

By Barb Gorges

Also published at Wyoming Network News and the Wyoming Tribune Eagle.

Raptors were the stars of a late January field trip taken by the Cheyenne – High Plains Audubon Society.

We visited the Rocky Mountain Arsenal National Wildlife Refuge on the outskirts of Denver, only 90 minutes from Cheyenne.

The man at the visitor center desk told us the bald eagles were at Lower Derby Lake. He was right.

Farther down the road we found a bald eagle on top of a utility pole calmly eating something furry for lunch, either one of the numerous prairie dogs or a rabbit. Several photographers snapped away. No one got out of their cars because we were still in the buffalo pasture where visitors, for their own safety, are not allowed out of their vehicles. But vehicles make good blinds and the eagle seemed unperturbed.

2018-02RockyMtnArsenalNWRbyBarbGorges

Winter is a good time to look for raptors. They show up well among naked tree branches and on fence posts, though we noticed mature bald eagles look headless if they are silhouetted against a white winter sky—or the snow-whitened peaks of the Colorado Rockies. Our checklist for the Arsenal included rough-legged hawk, red-tailed hawk, and some unidentifiable hawks.

On the way home, we stopped in Fort Collins because a Harris’s hawk, rare for the area, was reported hanging around the Colorado Welcome Center at the East Prospect Road exit. The center volunteers told us all about it—and that we were several days late. But they knew where the local bald eagle nests were and were proud of the other hawks that could be seen right outside the window.

Raptors, generally defined as hawks, eagles, falcons and sometimes vultures, sometimes owls, are a popular category of bird. When our Audubon chapter sponsored the Buffalo Bill Center for the West’s Raptor Experience last spring, more than 100 people crowded into the biggest meeting room at the library to see live hawks, falcons and owls.

Maybe we are fascinated by raptors because their deadly talons and powerful beaks give us a little shiver of fear. Or maybe it’s because they are easy to see, circling the sky or perched out in the open. Even some place as unlikely as the I-25 corridor makes for good hawk-watching. I counted 11 on fence posts and utility poles in the 50 miles between Ft. Collins and Cheyenne on our way home from the field trip.

Since I was driving, I didn’t give the birds a long enough look to identify them. But I bet I know who could—Pete Dunne.

Dunne watches hawks at Cape May, New Jersey, during migration. After more than 40 years, most as director of the Cape May Bird Observatory, he can identify raptor species when they are mere specks in the sky—the way motorists can identify law enforcement vehicles coming up from behind. It’s not just shape. It’s also the way they move.

2018-02BirdsofPreyDunne&Karlson            Dunne is co-author of “Hawks in Flight: A Guide to Identification of Migrant Raptors.” Last year he authored a new book with Kevin T. Karlson, “Birds of Prey, Hawks, Eagles, Falcons, and Vultures of North America.”

This is not your typical encyclopedia of bird species accounts. Rather, it is Dunne introducing you to his old friends, including anecdotes from their shared past.

You will still find out the wingspan of a bald eagle, 71-89 inches, and learn about the light and dark morphs (differences in appearance) of the rough-legged hawk.

But Dunne also gives you his personal assessment of a species. For instance, he takes exception to the official description of Cooper’s hawk (another of our local hawks) in the Birds of North America species accounts as being a bird of woodlands. After years of spending hunting seasons in the woods, he’s never seen one there.

Dunne is even apt to recite poetry, such as this from Alfred, Lord Tennyson’s “The Eagle”:

He clasps the crag with crooked hands;

Close to the sun in lonely lands,

Ring’d with the azure world, he stands.

This is not a raptor identification guide, but since there are photos on nearly every page—an average of 10 per species showing birds in all kinds of behaviors, you can’t help but become more familiar with them—and more in awe.

At 300 pages, this is not a quick read, but it is perfect preparation for a trip to the Arsenal or for finding out more about the next kestrel you see.

Year of the Bird celebrates 100th anniversary of Migratory Bird Treaty Act

By Barb Gorges

This is the Year of the Bird. It’s been declared by four august organizations: the National Audubon Society, the National Geographic Society, Cornell Lab of Ornithology and BirdLife International. A hundred other organizations have joined them.

My husband Mark and I have been members for years of the first three, and I’m on the email list for the fourth so I’ve heard the message four times since the first of the year.

The Year of the Bird celebrates the 100th anniversary of the Migratory Bird Treaty Act that protects birds. Read the act at https://www.fws.gov/birds/policies-and-regulations/laws-legislations/migratory-bird-treaty-act.php (remember “take” is a euphemism for “kill”).

The Year of the Bird is also about advocating for birds. Today you can go to the National Geographic website, https://www.nationalgeographic.org/projects/year-of-the-bird/, and sign the Year of the Bird pledge. You’ll receive monthly instructions for simple actions you can take on behalf of birds. The official Year of the Bird website, www.birdyourworld.org, will take you to the National Geographic page, and the other sponsors’ websites will get you there as well.

You may not be aware of National Geographic’s bird credentials. When the National Geographic Field Guide to the Birds of North America came out in the 1980s, it was a must-have sensation. You can find the latest edition at local bookstores and online.

The National Audubon Society, http://www.audubon.org/yearofthebird, is your portal to these articles so far: How Birds Bind Us, The History and Evolution of the Migratory Bird Treaty Act, The United States of Birding and Audubon’s Birds and Climate Change Report. My favorite–Why Do Birds Matter? – quotes dozens of well-known authors and ornithologists.

BirdLife International, http://www.birdlife.org/worldwide/news/flyway, offers ways to think about birds. When you see your next robin, think about where it’s been, what it’s flown over. Think about the people in other countries who may have seen the bird too. Think about the work being done to protect its migratory flyways.

On the other hand, the Cornell Lab of Ornithology begins the year addressing bird appreciation. At one of their websites, https://www.allaboutbirds.org/6-resolutions-to-help-you-birdyourworld-in-2018/, Hugh Powell recommends getting a decent pair of affordable binoculars after reading this guide on how to shop for them, https://www.allaboutbirds.org/six-steps-to-choosing-a-pair-of-binoculars-youll-love/.

Powell also recommends CLO’s free Merlin Bird ID app to get to know your local birds better (or see http://www.AllAboutBirds.org). Then you can keep daily bird lists through CLO’s free eBird program, including photos and sound recordings.

While you watch birds from your kitchen window, drink bird-friendly, shade-grown coffee. There’s an in-depth article at https://www.allaboutbirds.org.

Or play CLO’s new Bird Song Hero game to help you learn how to match what you hear with the visual spectrograph, https://academy.allaboutbirds.org.

Finally, Powell suggests “pay it forward”—take someone birding and join a bird club or Audubon chapter (locally, I’d recommend my chapter, https://cheyenneaudubon.wordpress.com/).

Here in Wyoming our lone U.S. Representative, Congresswoman Liz Cheney, has attempted to take the teeth out of the Migratory Bird Treaty Act with H.R. 4239. She thinks protecting birds should not come at the expense of business.

Earlier threats to birds caused conservationist Aldo Leopold to write in his 1949 book, A Sand County Almanack, “We face the question whether a still higher ‘standard of living’ is worth its cost in things natural, wild, and free. For us of the minority, the opportunity to see geese is more important than television, and the chance to find a pasqueflower is a right as inalienable as free speech.”

I would say that people who appreciate birds are not a minority. And many of us agree with biologist and biodiversity definer Thomas Lovejoy, “If you take care of birds, you take care of most of the environmental problems in the world.”

If it is too cold for you to appreciate the birds while outside, check out National Geographic’s January issue with photos by Joel Sartore. More of his bird photos for National Geographic’s Photo Ark project, studio portraits of the world’s animals, will be in a book coming out this spring written by Noah Strycker, “Birds of the Photo Ark.” Strycker will be speaking in Cheyenne May 14.

Now go to www.BirdYourWorld.org and take the pledge and find out each month what simple action you can take on behalf of birds.

Addendum: Because the paragraph about Liz Cheney was omitted from the column when it was published in the Wyoming Tribune Eagle, I submitted a letter to the editor that was published four days later:

Migratory Bird Treaty Act under attack

Dear Editor,

2018 is the 100th anniversary of the Migratory Bird Treaty Act. The U.S., along with co-signers Mexico, Canada, Japan and Russia, agree to protect birds that cross our borders and theirs.

A hundred years ago there was a battle between conservationists and industrialists and the birds won. Industry is now held accountable for “incidental take” – birds killed unintentionally during the course of business. That has included birds hooked by long-line ocean fishing, birds attracted to oily evaporation ponds in oil and gas fields and birds hit by wind turbines.

These kinds of hazards can add up and make a population-threatening dent. Instead, the MBTA has forced industries to pay fines or come up with ingenious solutions that save a lot of birds.

However, Wyoming’s Congresswoman Liz Cheney is backing U.S. House Resolution 4239 which would remove the requirement to take responsibility for incidental take. Here we are, 100 years later, fighting the battle again.

If you would like to speak up for the birds, please call Cheney’s office, 202-225-2311. The polite person who answers the phone only wants to know your name, address and your opinion, so they know which column to check, anti-bird, or pro-bird and the MBTA.

Also published at Wyoming Network News

By Barb Gorges

I took part in two different Christmas Bird Counts last month.

The Guernsey-Fort Laramie 7.5-mile diameter count circle is centered where U.S. Hwy. 26 crosses the line between Goshen and Platte counties, halfway between the towns. Guernsey’s population is 1,100, Fort Laramie’s is 230, while the Cheyenne count is centered on the Capitol amidst 60,000 people.

All of the species in the combined list below have been seen on previous CBCs in Cheyenne, except for the canyon wren.

Guernsey is 80 miles north of Cheyenne, but 1600 feet lower. Cheyenne’s few small reservoirs were nearly entirely frozen this year. However, within the other count circle are Guernsey Reservoir, on the North Platte, and part of Grayrocks Reservoir on the Laramie River There was more open water on the day of that count, Dec. 17, so you’ll see more ducks listed compared to Cheyenne’s, held Dec. 30.

The cliffs along the North Platte have juniper trees with berries, attracting lots of robins and solitaires. Cheyenne, on the other hand, has lots of residential vegetation and more bird feeders.

There were 16 people on the Cheyenne count, about 10 on the other. We take the same routes every year and statistical analysis of time and distance travelled smooths things out for scientists using our data.

Jane Dorn, the compiler for the Guernsey-Fort Laramie count, includes certain subspecies in her reports when possible. Of her 14 northern flickers, one was yellow-shafted (yellow wing-linings), like the flickers in eastern North America.

Dorn also sorts out dark-eyed juncos. Of the 33 on her count, eight were slate-colored (the junco of eastern North America), one was white-winged (range centered on the Black Hills) and three were Oregon. The other 21 were either difficult to see or hybrids—the reason there are no longer multiple species of juncos with dark eyes.

Dorn had four adult and two immature bald eagles. Those of us coming up from Cheyenne missed a chance for seeing them when we skipped Greyrocks Reservoir while delaying our trip two hours for black ice on I-25 to melt.

The weather for the Cheyenne count put a damper on the number of songbirds out in the morning when we have the most people participating. Dec. 30 was when everything was thickly covered in fluffy ice crystals. Serious birders shrugged off the 7-degree temperature and were rewarded with beauty. By lunch time, I was shrugging off layers to keep cool when the day’s high reached 56 degrees.

Cheyenne count compiler Greg Johnson noted raptors were well represented this year, with 10 species observed, the rough-legged hawk the most abundant with 13 seen, and the two merlins the most unusual.

Johnson said, “Three lingering red-winged blackbirds were visiting a feeder at the Wyoming Hereford Ranch. Otherwise, no unexpected or rare species were observed.”
