Parental Behavior Controls Incubation Period and Asynchrony of Hatching in Magellanic Penguins: Reply to Demongin, Poisbleau and Eens (2013)

[摘要] Abstract. We defined incubation period as the time from the laying of an egg to its hatching (Rebstock and Boersma 2011) because this full period is ecologically important and matters to both parents' and offspring's fitness. Birds have many patterns of incubation onset and various degrees of egg neglect following onset of incubation. Onset of incubation is difficult to measure in the field and even if known, ignoring the period before onset of incubation misses many of the selective forces acting on incubation patterns and periods.
