(Parabuteo unicinctus)
of Adult:
Medium sized, dark sooty brown hawk with chestnut colored shoulders, underwing linings and thighs, with a boldly marked black and white tail set off by a white rump and white tail coverts
Rather tame, perches conspicuously near roads on utility poles, fence posts and trees; flights are very low to the ground for sneak attacks; one of the few social birds of prey: hunt in groups of 4-5 and share kill. Stacking: stack on each other's shoulders atop a cactus for better view of prey
Song is loud, harsh, nasal screams of "jaaahrr." Predators are other raptors, canines and felines.
