Description: Article describing how some birds adopt the strategy of grouping their young, leaving them with a guardian while both parents go off to forage.
he fledglings of some bird species such as Greater Flamingos, Royal and Sandwich Terns, eiders, ostriches, and a number of penguins separate from their parents and form a group, or "creche." Whether parents continue to feed their own chicks, or the chicks feed themselves, supervision of the creche (when it occurs) is usually delegated to a small number of guardians. The guardians, of course, are related to only a small number of the young in the group. It is curious that "altruistic" guarding of unrelated young, presumably a dangerous, tiring responsibility, has evolved. Upon closer scrutiny, however, the behavior is not as altruistic as it appears.
