This immature Harlan's Red-tailed Hawk is striking with those white polka dot spots on its back, I don't think I have ever seen a young Red-tail where the white spots on the scapulars are so pronounced.
Harlan's Hawks are a subspecies of Red-tailed Hawks that breed in Alaska and northern Canada and spend their winters in the northern Great Plains.
I haven't had many opportunities to photograph the Harlan's subspecies of the Red-tailed Hawk so I was thrilled yesterday when I spotted a juvenile dark morph Harlan's Hawk feeding on a dead American Coot on the bank of a creek.
