spur-winged goose

The spur-winged goose is a long-legged African goose belonging to the genus Plectropterus. A notable characteristic of this bird is the presence of a strong spur on the bend of its wing. The term "spurwing" can also refer to the spur-winged plover.12

Within the broader classification of anseriform birds, which includes geese, ducks, and swans, there is significant variation in anatomical features adapted for different lifestyles. Geese, for instance, have developed strong bills suitable for grazing. Some waterfowl possess horny knobs at their wrist joints, and in species like the spur-winged goose, these manifest as distinct spurs that can be used for defense.3
