Looks like I've been educated

In the states, a buzzard is a vulture. Live and learn !
It's confusing that America has adopted common names which don't respect the actual taxonomy.
Within the hawk family (
Accipitridae), buzzards are assigned to the genus
Buteo and true hawks assigned to the genus
Accipiter.
For the North American continent, despite having the popular name of “hawk”, the Broad-winged Hawk, Ferruginous Hawk, Gray Hawk, Gray-lined Hawk, Red-shouldered Hawk, Red-tailed Hawk, Rough-legged Hawk, Short-tailed Hawk, White-tailed Hawk and Zone-tailed Hawk are all buzzards in the genus
Buteo. The Roadside hawk was also in
Buteo, but is now generally reassigned as the sole member of the
Rupornis genus.
Only Cooper's Hawk, the Goshawk(s), Sharp-shinned Hawk and Swainson's Hawk are assigned to the genus
Accipiter as true hawks.
Additionally, the North American continent also has the buzzard-related species of Common Black-Hawk (
Buteogallus anthracinus) and Harris's Hawk (
Parabuteo unicinctus).
Vultures in America are related, but assigned to multiple genera in the condor family (
Cathartidae).
