The Galapagos Penguin is the only penguin in the Galapagos.  Their population flucuates between a few thousand and a few hundred birds.  Their population dramatically declines after El Nino years.  
 
Both sexes are alike, although males are slightly larger than females.  They make a braying sound, similar to that of a donkey.  They are flightless and dive to feed.
