Merlin at Tulelake

Merlin, Tulelake, California, 18 February 2012 by Greg Gillson.

 

More photos from the Winter Wings Festival in Klamath Falls, Oregon, last week, February 17-19, 2012. (See previous posts.)

After chasing the Common Redpoll in Tulelake, California, Brian Sullivan and I spotted this Merlin on a fencepost. Using the car as a blind, Brian drove while I photographed out the window.

Did you know that falcons have round nostrils? It's true! See the upper photo.

See a previous post on Merlin (Black Bullet.) The subspecies in this previous post is the Black Merlin (F. c. suckleyi), while the bird in today's photos is the Taiga Merlin (F. c. columbarius). The Prairie Merlin (F. c. richardsonii) is very pale.

Which photo do you like better?

Last week I was able to get a couple of decent photos of a Merlin. These birds tend to be wary and speedy!

While superficially the size and shape of an American Kestrel, in flight the Merlin is a race car to the Kestrel's moped. The Merlin never hovers!

Merlins tend to favor open country where they often hunt from low perches. Even migration is low and direct--hugging the terrain, just over the shrub-tops. When they see their prey (usually other small birds or dragonflies) they pursue in quick, direct flight. They then may take their prey to a perch (top of a telephone pole or fence post in open country) to pluck and eat.

This particular bird is the subspecies suckleyi, formerly called the Black Pigeon Hawk. It is very dark--and heavily streaked below. This race breeds in British Columbia and winters along the coast to southern California.

I have noted this species chasing shorebirds in coastal estuaries and Pine Siskins over coastal sitka spruce forests. Once I noted a flock of Bushtits flying (crawling through the air) over the beach at the south jetty of the Columbia River. Silly birds. A Merlin flew leisurely (for a Merlin) and snatched a Bushtit out of the air without breaking stride.

Other races of Merlins are found September through April in the Pacific Northwest. The Prairie race (richardsonii) is very pale blue-gray, females pale tannish-gray. The northern taiga form (columbarius) is intermediate (see The Sibley Guide to Birds ).
