Raptors are popular birds; new book celebrates them

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.

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.
