By Barb Gorges

I’m very good at procrastinating. How about you? But I’ve discovered there are some advantages.

From 2008 to 2010, I wrote “Bird of the Week” blurbs for the Wyoming Tribune Eagle to run in those sky boxes at the top of the To Do section pages. But they needed photos.

I asked one of the Wyobirds e-list subscribers from Cheyenne, Pete Arnold. Pete invites people to join his own e-list, where he shares his amazing bird photos. He generously agreed.

Using the checklist of local birds prepared by Jane Dorn and Greg Johnson for the Cheyenne-High Plains Audubon Society, I chose 104 of the most common species and set to work figuring out which weeks to assign them to. Pete perused his photos and was able to match about 90 percent.

We eventually met in person–at Holliday Park. Pete stopped on his way to work one morning to snap waterfowl photos and I was walking a friend’s dog and counting birds. We discovered we have several mutual friends.

By the time our two-year project was over, I’d heard about making print-on-demand books, uploading files via internet for a company to make into a book. I rashly promised Pete I’d make a book of our collaboration. After the paper published BOW, I had all the rest of the rights to the text. And I’ve had college courses in editing and publishing.

Here’s where my procrastination comes in. Over the next six years my family had three graduations, three weddings, three funerals and two households to disassemble, not to mention my husband Mark retired and wanted to travel more.

Finally, a couple years ago, I gave print-on-demand a trial run through Amazon, designing my small book about quilt care. I realized then the bird book would be beyond my talents and software. I considered learning InDesign but also started looking for a professional.

I discovered, through the social media site LinkedIn, that Tina Worthman designed books in her spare time. We’d started talking when she got the job as director of the Cheyenne Botanic Gardens. No more spare time.

However, Tina recommended Chris Hoffmeister and her company, Western Sky Design. What a great match—she’s a birder! I didn’t have to worry about her mismatching photo and text. And she could speak to Pete about image properties and other technicalities.

Song Sparrow - Pete Arnold

Song Sparrow by Pete Arnold from “Cheyenne Birds by the Month.”

The book features a 6 x 6-inch image of each bird. Chris asked Pete to provide bigger image sizes, since the small ones he’d used for the paper would be fuzzy. He also had to approve all the cropping into the square format. But the upside of my procrastination is he had more photos to choose from.

There were still a few species Pete didn’t have and so we put out a call on Wyobirds. We got help from Elizabeth Boehm, Jan Backstrom and Mark Gorges.

Meanwhile, even though the WTE features editor at the time, Kevin Wingert, had originally edited BOW, I sent my text for each species, and all the other parts of the book (introduction, acknowledgements, word from the photographer, bird checklist, resources list), to Jane Dorn, co-author of the book Wyoming Birds. Another friend, Jeananne Wright, a former technical writer and editor, and non-birder, caught a few ambiguities and pointed out where I’d left non-birders wondering what I meant.

The title of the book was the last step. Instead of naming it Bird of the Week, two years’ worth of bird images and written bird impressions/trivia are organized differently. The title is “Cheyenne Birds by the Month, 104 Species of Southeastern Wyoming’s Resident and Visiting Birds.”

The book is being printed by local company PBR Printing—print-on-demand is too expensive for multiple copies.

While the book will be available late October at the Wyoming State Museum and other local outlets, our major marketing partner is the Cheyenne Botanic Gardens, a natural fit since it is in the middle of Lions Park, a state Important Bird Area.

The Gardens will have the book available at their gift shop and at two book signings they are hosting: Tuesday, Nov. 20, 11:30 a.m. – 1 p.m. and Sunday, Dec. 9, 1 – 3 p.m., 710 S. Lions Park Dr.

You can get a sneak peak, and Pete’s behind the camera stories, at our presentation for Cheyenne Audubon Oct. 16, 7 p.m. in the Cottonwood Room at the Laramie County Library, 2200 Pioneer Ave.

For more information about the book and updates on where to find it, see Yucca Road Press, https://yuccaroadpress.com/. If you don’t live in Cheyenne but would like to order a copy, please email bgorges4@msn.com.

It took part of a village to make this book and we are hoping the whole village will enjoy reading it.

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.

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

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!

How well do birds tolerate people?

2018-03TurkeyVulturebyMarkGorges-1

Every soaring bird I saw in early February along 1300 miles of interstate highway between Nashville, Tennessee, and Fort Lauderdale, Florida, was a black vulture or turkey vulture.

However near Vero Beach, Florida, where we were visiting Cheyenne snowbirds Karen and Fred Pannell, there was a black bird of a different shape, a magnificent frigatebird, a life bird for both me and my husband Mark.

But about those vultures, were they really more abundant along the interstate than away from it? Were they waiting for roadkill? We passed a couple landfill “mountains” that were big vulture magnets too.

We think wild birds go about their lives oblivious to people, or at least avoiding us. Except for birds coming to feeders. Or ducks at the park looking for handouts. Or Canada geese that enjoy eating the grass on park lawns and the leftover grain in farmers’ fields.

We know that some human activities are detrimental to birds. But how many are beneficial to them? Chimney swifts have experienced both. We took down the old hollow trees they used to build their nests in and they moved into our chimneys.

The speaker at February’s Cheyenne – High Plains Audubon Society meeting, Cameron Nordell, relayed interesting research results on nesting ferruginous hawks and their reactions to people. Nordell, Raptor Fellow at the University of Wyoming Biodiversity Institute, is with the Wyoming Raptor Initiative.

In his previous work in southern Alberta, Nordell and his colleagues experimented in part to see at what distance hawks would flush from their nests as researchers approached by vehicle or on foot to check the nests for other aspects of the study.

Southern Alberta is a mix of agriculture, oil and gas and other development. The farmers and home owners have planted trees on the prairie and the ferruginous hawks have found them to be great for nesting—they are a ground-nesting hawk otherwise. The trees give them better protection from predators.

However, along with people came another species that climbs trees—and raids nests—racoons. Barns and other structures have helped increase the population of great horned owls and they too prey on the nestlings.

Ferruginous hawks nesting near the busiest roads were more tolerant than birds that had not seen as much traffic. Approaching vehicles were tolerated better than approaching people.

Raptors have been shown to hang out by roads, looking for injured prey species. The problem is that they risk getting hit by vehicles too.

The Wyoming Raptor Initiative (see https://wyomingbiodiversity.org/Initiatives-Programs) wants to understand the state’s raptors better, including the road problem. It has two goals:

“(1) To synthesize our scientific understanding of raptors in Wyoming so that the public, scientists, land managers and energy companies will be better informed in developing and implementing future conservation strategies and land mitigation efforts.

“(2) To foster appreciation of raptors in Wyoming and the world through education and outreach efforts.”

Nordell and his colleagues will be looking at previous studies of raptors in Wyoming, gathering more data, talking to all kinds of people to get more information, and then they’ll relay what they learn.

What will they discover about Wyoming’s ferruginous hawks, for instance? What human activities help them or harm them?

Nordell also studied arctic peregrine falcons near Hudson Bay, where there were few direct human impacts. However, the weather was ferocious. Too much rain, and a young bird, poorly nourished, could succumb to the cold rainwater collecting in the cliff-face nest. Better-fed youngsters had better survival rates.

The next questions: What affects the availability of peregrine prey species and the peregrine parents’ ability to bring food back to the nest? Is there any human influence on their success? Are humans linked in any way to that Arctic location getting demonstrably rainier?

What will be discovered about peregrines in Wyoming? I watched one nail a duck on a ranch reservoir just outside Cheyenne once. The human-made lake attracted the peregrine’s food target—southeastern Wyoming doesn’t have many natural water bodies.

I look forward to answers from the Wyoming Raptor Initiative. I’m sure they will also discover many more questions.

Sage grouse captive breeding success doubtful

220px-Centrocercus_urophasianus_-USA_-male-8 Wikipedia

Greater Sage-grouse. Photo courtesy Wikipedia.

Published Dec. 10, 2017, in the Wyoming Tribune Eagle, “Critics of sage grouse captive breeding doubt it will succeed.”

Note: The American Ornithological Society’s spelling is “Greater Sage-Grouse.”  The Associated Press style when the full name is not used is “sage grouse.”

By Barb Gorges

Over the eons, the greater sage-grouse figured out how to prosper in the sagebrush.

It’s not an easy life. Some years are too wet and the chicks die. Others are too dry with few leaves, buds, flowers or insects and the chicks starve. Some years there are too many hungry coyotes, badgers and ravens.

Every spring the sage grouse go to the meet-up at the lek, the sage grouse version of a bar [To find where to see sage grouse in Wyoming go to https://wgfd.wyo.gov/Habitat/Sage grouse-Management/Sage grouse-Lek-Viewing-Guide]. The males puff out their chests vying for the right to take the most females, then love them and leave them to raise the chicks on their own.

Experienced hens look for the best cover for their nests. They teach the young how to find food and avoid predators. In fall, every sage grouse migrates to winter habitat, 4-18 miles away.

In the past hundred years, obstacles were thrown in the path of sage grouse, including in their Wyoming stronghold where sagebrush habitat can be found across the whole state except in the southeast and northwest corners.

The low-flying birds collide with fences, vehicles, utility lines. The noise from oil and gas operations pushes them away. Sagebrush disappears with development.

Each state is responsible for all wildlife within its borders. But if a species heads for extinction, the U.S. Fish and Wildlife Service steps in. Since 1985, the sage grouse population declined 30 percent across the West. It looked like the species might be listed as either threatened or endangered, curtailing oil and gas drilling and other development.

Last month I explained how Wyoming conservationists, sportsmen, the oil and gas industry, agricultural interests and state and local government collaborated on a state plan to conserve sage grouse. However, the current federal administration wants all the state plans to be examined to see if sage grouse habitat can be more densely developed.

Wyoming’s collaborators strongly disagree with the attempt. Public comments were solicited by the Bureau of Land Management through the end of November and the Forest Service is taking comments through January 5 [https://www.federalregister.gov. In the search area type: Ask Forest Service to Amend Greater Sage-Grouse Land Use Plan.].

Meanwhile, a Wyoming man is hoping to change the dynamics of the sage grouse issue by increasing their population through captive breeding.

Diemer True, of the True Companies (oil and gas drilling, support, pipelines, and seven ranches), and former president of the Wyoming Senate, bought Karl Baer’s game bird farm in Powell.

True convinced the Wyoming Legislature to pass legislation during the 2017 session to allow him and Baer to apply for a permit allowing them to take up to 250 sage grouse eggs from the wild per year and experiment for five years with captive breeding. The idea is that birds can be released, bring up the numbers and maybe allow higher density of development in protected areas.

But no one has been very successful captive breeding sage grouse. No one has successfully released them to procreate in the wild and, if True is successful, he wants his techniques to be proprietary—he won’t share them. He wants to profit from wildlife rather than take the more typical route of supporting academic research.

Gov. Matt Mead signed the captive breeding legislation into law this fall. The Wyoming Game and Fish Commission wrote very specific regulations about it, which you can read at https://wgfd.wyo.gov/Regulations/Regulation-PDFs/REGULATIONS_CH60.

Five permits are allowed, for a total withdrawal of 1,250 eggs per year, but it is doubtful that anyone besides True and Baer will qualify. Consensus among wildlife biologists I spoke to is that True will have trouble finding 250 wild eggs for his permit.

The facility requirements mean True is building new pens separated from the bird farm’s other operations. Despite these best management practices, there’s still a chance captive-bred birds could infect wild birds when they are released.

[The Wyoming Game and Fish Department monitors sage grouse leks every spring to see how successful the previous year’s breeding was. Numbers naturally vary widely year to year. The effects of captive breeding on these surveys will be included when setting hunting limits.]

No one who knows sage grouse well believes they can be bred in captivity successfully. Young sage grouse learn about survival from their mothers. By contrast, the non-native pheasant captive-bred here is acknowledged to be a “put-and-take” hunting target. It hardly ever survives to breed on its own.

We can only hope that this sage grouse experiment will go well. If captive-bred chicks don’t thrive in the wild, there will be some well-fed coyotes, badgers and ravens.

Watch bird family dramas via window TV

2017-09 Lesser Goldfinch and young--Mark Gorges

A Lesser Goldfinch father prepares to feed his begging offspring Aug. 4, 2017, in our Cheyenne backyard. Photo by Mark Gorges.

Published in the Wyoming Tribune Eagle Sept. 17, 2017, “Kitchen window like TV peering into lives of birds”

By Barb Gorges

The view out our 4-by 6-foot kitchen window is the equivalent of an 85-inch, high definition television screen.

The daytime programming over the summer has been exceptional this year. Not many murder mysteries, thank goodness, and instead, mostly family dramas.

The robins always seem to get on screen first. Walking flat-footed through our vegetables and flowers, the speckle-breasted young, unlike some human teenagers, kept looking towards the adults for instruction and moral support.

Young birds have this gawky look about them. They have balance issues when they land on the utility line. Or they make a hard landing on a branch. They look around, tilting their heads this way and that. Maybe they are learning to focus.

The first hummingbird of the season showed up July 10, nearly a week earlier than last year. Luckily, their favorite red flower, the Jacob Cline variety of monarda, or beebalm, was blooming two weeks ahead of schedule.

We immediately put the hummingbird feeder up (FYI: 4 parts water to 1 part white sugar—don’t substitute other sugars—boiled together, no red dye, please, maybe a red ribbon on the feeder). Within a few days we had a hummingbird showing up regularly at breakfast, lunch and dinner—which is when we watch our window TV.

Sometimes we saw three at a time, often two, though by Aug. 25 sightings dropped off. It is difficult to distinguish between rufous and broad-tailed females and juveniles that come. Kind of like trying to keep track of all the characters in a PBS historical drama.

My favorite series this summer was “Father Knows Best.” Beginning July 1, a lesser goldfinch male, and sometimes a second one, and females, started joining the American goldfinches at our thistle tube feeder.

The lesser goldfinch is the American goldfinch’s counterpart in the southwestern U.S. and they are being seen more regularly in southeast Wyoming. They are smaller. Like the American, they are bright yellow with a black cap and black wings, but they also have a black back, although some have greenish backs.

Every day the lesser males showed up, pulling thistle seed from the feeder for minutes at a time. Unlike other seed-eating songbirds which feed their young insects, goldfinches feed their young seeds they’ve chewed to a pulp. After a couple weeks, we began to wonder if one of them had a nest somewhere.

August 4, the lesser fledglings made their TV debut. The three pestered their dad at the same time. My husband, Mark, got a wonderful photo of the male feeding one of the young. However, within five days the show was over, the young having dispersed.

Year-round we have Eurasian collared-doves. I’ve noticed one has a droopy wing, the tip of which nearly drags on the ground. She and her mate are responsible for the only X-rated content shown on our backyard nature TV—that’s how I know the droopy-winged bird is female.

One morning outside I noticed a scattering of thin sticks on the grass and looked up. I saw the sketchy (as in a drawing of a few lines) nest on a branch of one of our green ash trees, with the dove sitting on it. Every time I went out, I would check and there she was, suspended over our heads, listening in on all our conversations, watching us mow and garden.

Then one day I heard a frantic banging around where Mark had stacked the hail guards for our garden. It was a young dove. It had blown out of the nest during the night’s rainstorm. The sketchy (as in unreliable) nest had failed.

The presence of the trapped squab, half the size of an adult, would explain the behavior of the mother nearby, who had been so agitated that she attracted our dog’s attention.

I put the dog in the house and went to extract the young bird. It didn’t move as I approached and scooped it up. There is something magical about holding a wild bird, even one belonging to a species that has invaded our neighborhoods, sometimes at the expense of the native mourning dove. So soft, so plump. I set it down inside the fenced-off flower garden. Later, I checked and it was gone.

Within a few days, Droopy-wing and her mate were involved in another X-rated performance. Then I noticed one of them fly by with a slender stick. Sure enough, two days later she was back on her rehabbed throne, incubating the next generation.

Bird books worth reading

Published Mar. 12, 2017 in the Wyoming Tribune Eagle, “Bird books worth reading.”

By Barb Gorges

If you are the books you read, here is what I’ve been this winter.

2017-3Genius of BirdsThe Genius of Birds” by Jennifer Ackerman, c. 2016, Penguin Press

This was a Christmas present from my daughter-in-law, Madeleine, who teaches cognitive psychology. It’s an enthralling overview of the latest studies that show how much smarter birds are than we thought, sometimes smarter than us in particular ways. They can navigate extreme distances, find home, find food stashed six months earlier, solve puzzles, use tools, sing hundreds of complex songs, remember unique relationships with each flock member, engineer nests, adapt to new foods and situations. They can even communicate with us.

2017-3GoodBirds“Good Birders Still Don’t Wear White, Passionate Birders Share the Joys of Watching Birds,” edited by Lisa A. White and Jeffrey A. Gordon, c. 2017, Houghton Mifflin Harcourt

The previous volume, in 2007, was “Good Birders Don’t Wear White, 50 Tips from North America’s Top Birders.”

One of my favorite essays is by our Colorado friend Ted Floyd, “Go Birding with (Young, Really Young) Children.” Having frequently accompanied him and his children, I can say he does a terrific job of making birdwatching appealing.

Many of the essays start out with “Why I Love…” and move on to different aspects of birding people love (seabirds, drawing birds, my yard, spectrograms, “because it gets me closer to tacos”), followed by tips should you want to follow their passions.

2017-3ABACalifornia“Field Guide to the Birds of California” by Alvaro Jaramillo, c. 2015

This is part of the American Birding Association State Field Guide Series published by Scott & Nix Inc. The series so far also includes Arizona, the Carolinas, Colorado, Florida, Minnesota, New Jersey, New York, Pennsylvania and Texas.

Each author writes their own invitation to the beginning birdwatcher or the birder new to their state.

While a few birding hotspots may be mentioned, the real service these books provide is an overview of the state’s ecological regions and what kind of habitats to find each species in, not to mention large photos of each. I’ll probably still pack my Sibley’s, just in case we see a bird rare to California.

2017-3PetersonGuidetoSong            “Peterson Field Guide to the Bird Sounds of Eastern North America” by Nathan Pieplow, c. 2017, Houghton Mifflin Harcourt

While including the usual bird pictures and range maps, this book is about learning to identify birds by sound and corresponding audio files can be found at www.petersonbirdsounds.com.

Bird songs are charted using spectrograms, graphic representations of sound recordings.

You can think of spectrograms as musical notation. They read from left to right. A low black mark indicates a low-pitched frequency. A thin, short line higher up indicates a clear sound with few overtones, higher pitched and short-lived. But most bird sounds are more complex, some filling the spectrogram from top to bottom.

Pieplow explains how to read spectrograms, the basic patterns, the variations, the none-vocal sounds like wing-clapping, and the biology of bird sounds.

Once you can visualize what you are hearing, Pieplow provides a visual index to bird sounds to help you try to match a bird with what you heard.

Taking a call note I’m familiar with in my neighborhood, the one note the Townsend’s solitaire gives from the top of a tree in winter, I find that Pieplow categorizes it as “cheep,” higher than a “chirp” and more complex than “peep.” It’s going to take a while to train our ears to distinguish differences.

2017-3WarblerGuide            “The Warbler Guide” by Tom Stephenson and Scott White, c. 2015, Princeton University Press and The Warbler Guide App.

Spectrograms are a part of the 500 pages devoted to the 56 species of warblers in the U.S. and Canada.

The yellow warbler, whose song we hear along willow-choked streams in the mountains in summer, gets 10 pages.

Icons show its silhouette (sometimes it can be diagnostic), color impression (as it flies by in a blur), tail pattern (the usual underside view of a bird above your head), range generalization, habitat (what part of the tree it prefers) and behavioral (hover, creep, sally, walk).

Then there’s the spectrogram comparing it to other species and maps show migration routes and timing, both spring and fall. We can see the yellow warbler spends the winter as far south as Peru.

Forty-one photographs show all angles, similar species, and both sexes at various ages.

The companion app, an additional $13, has most of the book’s content, and lets you rotate to compare 3-D versions of two warblers at a time, filter identification clues and listen to song recordings.

This is a good investment for birding in Cheyenne where we have seen 32 warbler species over the last 20 springs.
