Use of European hare (Lepus europaeus) carcasses by an avian scavenging assemblage in Patagonia

We studied the use of European hare (Lepus europaeus) carcasses by avian scavengers in Argentinean Patagonia. A total of 16 hare carcasses were placed in locations that could be observed without disturbing birds feeding on them. Six avian species fed on these carcasses: chimango caracara (Milvago ch...

A total of 16 hare carcasses were placed in locations that could be observed without disturbing birds feeding on them. Six avian species fed on these carcasses: chimango caracara (Milvago chimango), crested caracara (Polyborus plancus), black vulture (Coragyps atratus), grey eagle-buzzard (Geranoaetus melanoleucus), red-backed hawk (Buteo polyosoma) and cinereous harrier (Circus cinereus).
