rough-legged
Legs with plumage
Rough-legged describes birds having feathers extending down the legs to the toes.
The term appears almost exclusively in the name of the rough-legged hawk (or rough-legged buzzard), an Arctic raptor that migrates south in winter.
The feathered legs provide insulation against cold climates.
