Flightless cormorant

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 is unable to to fly. This was probably caused by the lack of ground predators on the Galapagos, making flight useless.

The Flightless cormorant is the largest living species of cormorant, 89–100 cm (35–39.5 in) in length and weighing 2.5 –4kg.
