Flightless Cormorant Phalacrocorax harrisi

  • © Vivek KhanzodĂ©

The Flightless Cormorant is the only cormorant that has lost the ability to fly. Restricted to Fernandina and Isabela islands in the Galapagos archipelago, this species has a small population averaging about 1000 individuals. It is a large, brown cormorant with a relatively large head and small wings with very reduced remiges. The wings are useful, however, for maneuvering during surface-dives in search of fish, octopus, and squid. The population fluctuates widely with marine productivity. This species breeds year-round, sometimes twice in a year. Nests are constructed of seaweed and placed among the rocks above the high tide mark, generally in loose associations of several pairs.
