362. (American Ornithologists' Union check-list #) Audubon's Caracara: Polyborus cherivay (Jacq.) Adult--Crown and back black; upper back and nape slightly barred. Under parts: Throat and breast buff, the breast finely barred with black; belly black; feathers on crown slightly elongated; face bare. Length--23.00. Breeding Range--Southern Florida and Texas. The nests, which are not very bulky, are made of sticks and grass, either with or without lining, and placed in trees, amongst others the cabbage palmetto, and in bushes, rarely in cliffs. 2 to 3 eggs are laid; they are reddish or yellowish buff with small and large markings and cloudings of rich purplish brown, chestnut, and reddish brown. Size--2.40 x 1.70. These beautiful birds are fairly abundant in southern Florida; and though they sometimes come near the smaller towns, it is only when there is some special attraction, such as a slaughter house, that they assemble with the flocks of turkey vultures. More often they frequent the somewhat open country, away from human habitation. The breeding season begins in early March.
