In this system, females mate and lay eggs with multiple males over the course of a breeding season, leaving males to incubate the eggs and raise the chicks. of all bird species, is polyandry. 1996, Nakamura 1998).

Scientists were largely limited to studies birds in breeding colonies, at least those we knew about and that were accessible (and, if you think that’s a complete list, you haven’t read the news that came out this week about a new colony of Adélie penguins found in the Danger Islands, Antarctica).
