Alopochen aegyptiacus … note, this is Egyptian goose, not Egypt goose. But it is Canada
goos , not Canadian goose.
It might be called Egyptian goose because it looks like the old Egyptian paintings. Indeed, this goose is often depicted in ancient Egyptian art. Or maybe because it “walks like an Egyptian” (and by the way Egyptians don’t walk that way, only in the old paintings). But it is probably called an Egyptian goose for the same reason that the African buffalo is properly (in a vernacular sense) known as the Cape buffalo. The Cape buffalo entered the Linnaen Legacy via the observation of someone in what is now South Africa, and the Egyptian goose probably entered the pertinent literature from the perspective of someone working the other end of the African continent. It is, of course, much more widely distributed in Africa, wherever one finds geese as far as I know.
They pair for life, and they don’t spend to much time in water. Neither would you if you were a goose living in the land of the crocodiles. You’d be a siting duck. Your goose would be cooked. and so on.
I took this picture at the Kirstenbosch Gardens, in the vicinity of Cape Town, South Africa.
