Birds of Chignik Lake: Sharp-shinned Hawk – Sharp Claws and a Tomial Tooth

This handsome specimen occasionally hunted the grove of White Spruce trees where a variety of feeders attracted Pine Siskins, redpolls, crossbills and other passerines. That’s snow just behind his talons. (Chignik Lake, October 23, 2017)

“Tsst! Tsst!” I slowly turned to where Barbra was positioned 40 feet from where I’d set up. A subtle motion of her head directed me up into the spruce bows were a small, beautifully marked hawk was perched. I couldn’t believe how close he was. I knew I wouldn’t have more than moments in which to make a photo before I was noticed. Luckily, Barbra’s cue had drawn the bird’s attention to her, and since she was a relatively safe distance, the hawk didn’t seem to feel overly encroached upon. I swiveled the Wimberley-mounted lens toward where Barbra’s eyes were motioning, carefully tilting it up toward the bird’s perch. For almost two minutes the hawk cooperated and I was able to make some photographs. And then it was gone. The last frame I took shows only a blur of barred tail feathers.

I’d seen it before and I saw it again, but I never had another photo op like that. Focused on a newly arrived flock of Red Crossbills, I’d have missed my chance altogether had it not been for Barbra’s keen eyes. Come to think of it, it’s likely that those very same crossbills had the Sharp-shinned’s attention, tempting it to linger longer around a couple of humans than it otherwise might have.

Sharp-shinned Hawks are rare enough on the Alaska Peninsula that it isn’t included as part of their territory on most range maps. If you encounter one out here, you’re fortunate. Seldom found far from forests, Sharp-shinneds on the largely treeless peninsula are most likely migrants, merely passing through. The two copses of White Spruce trees and the feeders, which attracted the song birds that are this species’ favorite prey, no doubt induced it to hang around.

The protrusion on the upper bill of this Sharp-shinned Hawk is called a tomial tooth. It’s a trait shared by falcons, kites, and one group of songbirds, shrikes. Not actually a tooth, of course, the protrusion and the corresponding recess in the lower beak aid these predators in breaking the spines of small birds and other prey.
