Key differences
The Spur-winged Goose is much larger, has a more goose-like appearance, and possesses a prominent red knob on the bill (in males) and a spur on the bend of the wing. Its plumage is predominantly black with white underparts and face, but lacks the iridescent blue-black of the Comb Duck's back.
