HUNTING BEHAVIOR AND DIET OF COOPER'S HAWKS: AN URBAN VIEW OF THE SMALL-BIRD-IN-WINTER PARADIGM

We examined the predatory behavior of wintering urban Cooper's Hawks (Accipiter cooperii). Eight Cooper's Hawks (7 female, 1 male) were radio-tracked intensively during two winter periods from 1999–2001. We observed 179 attacks, 35 of which were successful, for an overall attack success ra...

Zusammenfassung:	We examined the predatory behavior of wintering urban Cooper's Hawks (Accipiter cooperii).

European Starlings (Sturnus vulgaris), Mourning Doves (Zenaida macroura), and Rock Doves (Columba livia) made up 95% of the prey attacked and 91% of the diet. Smaller birds (
