SWAINSON'S HAWK

This is my first time to get a photo of a Swainson's even though they are typically found in the West. According to Sibley, this is a dark morph.

 

In fall, they take off for Argentine wintering grounds—one of the longest migrations of any American raptor—forming flocks of hundreds or thousands as they travel. (Cornell)

 

Photographed on the Western Slope, Colorado.
