The Flightless Cormorant is unmistakably the only cormorant in the Galapagos, with functionless wings.  These birds are flightless and feed by diving inshore.  Both sexes are alike, although males are noticeably larger than females; their plumage is dark blackish - brown in the upper body and a paler brown lower body.  
 
The flightless cormorant has a population of 700 to 800 breeding pairs in 100 small colonies.  After El Nino years, their population dramatically declines.  These flightless birds breed throughout the year, although most eggs are laid from March to September.
