Several species are hunted in large numbers in parts of Greenland, Canada, and Alaska.
Eight species in the auk family mate at sea, an unusual breeding strategy. There are several possible reasons why this may be advantageous. Mating at sea may help auks avoid land predators. It may help male auks avoid competition and interference from other males of the same species. Finally, some biologists believe that female auks may use sea mating to figure out which males are healthiest and strongest, and would therefore make the best mates.
