I captured this Harris’s Hawk in my yard this morning. He was being harassed by some local Grackles.
Captured in Tucson, AZ.
Taken with my Canon EOS Rebel XS D1000.
Medium-sized to large hawk. Dark overall. White rump and undertail. White tip to dark tail. Chestnut-red thighs and shoulders. Legs and bare face skin yellow.
Juvenile similar to adults, except underparts streaked with cream or buffy coloration; amount of light color variable. Rufous patches reduced and dullish. Underwing has whitish primaries, conspicuous in flight. Tail crossed with many fine dusky bars; base and tip white.
The Harris’s Hawk nests in social units that vary from an adult pair to as many as seven individuals, including both adults and immatures.
Although most North American Harris’s Hawks nest in spring (March through June), some females will lay second and even third clutches after their first breeding attempt fails or succeeds. Eggs or young have been recorded in every month of the year.
Cooperatively hunting groups of Harris’s Hawks are more successful at capturing prey than individuals hunting alone. Groups of five hawks are the most successful.
