Collared Sparrowhawk Tachyspiza cirrocephala

Small, delicately-built gray raptor with orange barring on chest and belly. When soaring, tail-tip is notched when not fanned out. When perched, look for a tiny bill, blank-staring expression (no heavy brow), and very skinny legs. Much less likely to circle high in sky than Brown Goshawk, and tends to stick to cover.
