noun
buzzard
BUZ-erd/ˈbʌzərd/
A large bird that feeds mainly on dead animals.
The buzzard feeds on the carcass with its bare head lowered.

Etymology
Old French buisart named a harrier or an “inferior hawk.” English later extended this bird name to American vultures, giving it the scavenger sense used here.
In context
Now, buzzard has become something of a slang term for vultures here in the United States, but it's used much differently across the Atlantic.
