Notes: Sometimes confused with Bald Eagles, but much smaller and has black tail and black eye-stripe whereas the eagle’s tail and head are all white when adults. When Osprey’s are flying with a fish in their talons, they always hold the head of the fish forward, this is thought to make it much more aerodynamic in flight.

Length: 25”
Wingspan: 68”
Weight: 4 lbs

Plumage: Black on back, tail and wings. Red head and pale legs. From underneath in flight, Wing tips and trailing feathers are gray compared to rest of body. Babies are white down with black head.

Nesting: Found on the ground or in unused buildings. No nests are made, just a flat surface that may be scraped out a little. They usually lay 2 eggs that are incubated for about 38 days. Young fledge in about 11 weeks. If babies are found, leave them alone, they are supposed to be on the ground. Vultures are extremely susceptible to ‘imprinting’. If humans attempt to raise them, they will become attached to humans and can’t be released into the wild. Attempting to raise baby birds is against the law unless given state and federal permits.

Defense: Vultures will ‘throw up’ their food if they feel threatened.

Note: Turkey Vultures find food by smell. They can smell carrion over a mile away. Black Vultures will follow them because they do not have a good sense of smell.
