Phalacrocorax harrisi (Flightless Cormorant)

Synonyms: Nannopterum harrisi (homotypic); Nannopterum harrisi harrisi

Wikipedia Abstract

The flightless cormorant (Phalacrocorax harrisi), also known as the Galapagos cormorant, is a cormorant native to the Galapagos Islands, and an example of the highly unusual fauna there. It is unique in that it is the only cormorant that has lost the ability to fly. Once it was placed in its own genus, Nannopterum or Compsohalieus, although current taxonomy places it in the genus with most of the other cormorants, Phalacrocorax.
