Cinereous Vultures are large, dark-brown birds native to parts of Europe and Asia, with no natural wild range in the United States. Their broad, nearly rectangular wings can span 8–9.5 ft (2.4–2.9 m) as they soar over mountains and open country looking for dead animals. They are also called Eurasian black vultures.
The American Black Vulture (Coragyps atratus) is much smaller, with a wingspan of about 4.5–5 ft (1.4–1.5 m) and pale patches near the wingtips. The cinereous vulture can span 8–9.5 ft (2.4–2.9 m) and has broad, mostly dark wings.
Why they get mixed upBoth are dark scavenging birds, and Eurasian black vulture is another name for the cinereous vulture.
