  • The first-laid eggs of Eudyptes penguins are much smaller than second eggs, generally hatch later, and experience greater mortality, features that characterize a brood reduction system unlike that of any other avian group. Hypotheses that (1) first-egg mortality is incidental to aggressive behavior by nesting birds and (2) hatching asynchrony is created by preferential egg treatment during incubation were tested in a colony of Fiordland crested penguins (E. pachyrhynchus). Neither hypothesis… CONTINUE READING
