Flightless Cormorant*

(Phalacrocorax harrisi)

The Flightless Cormorant, which obtains all of its food by deep diving, and whose island habitat presents no enemies from which it needs to flee, has, in a kind of perverse Darwinian evolution, devolved its wings and thereby also the ability to fly.  It’s a perfect example of “use it or lose it.”
