Swainson's Hawk on our property

This is a bird we don't usually see in upstate New York.  Its primary territory is the western plains of North America, from Texas to the Yukon.  We have a pair of them on our property, and they have been here for about a week.  They are probably migrating through.


"The Swainson’s Hawk was first described in 1838 by Charles Bonaparte, French naturalist and ornithologist, and nephew of the Emperor Napoleon. It was named after William Swainson, a British naturalist." - whatbird website.
