magpie other plumage 4sq

Australian magpie flight feather.

This feather is assymmetrical and black down much of its length, distinguishing it to be a flight feather and not a tail feather, which are symmetrical and black only at the tips. Flight feathers are the large primary feathers in a bird's wing that support it in flight.
