Relaying propensity and characteristics of replacement clutches of Leach’s Storm-Petrels ( Oceanodromaleucorhoa)
Animals with low fecundity, such as seabirds, invest heavily into one or a few eggs per breeding attempt. The loss of these eggs can mean that individuals abandon breeding or invest in a replacement clutch. However, the ability of females to replace clutches may be costly and so replacement clutches...
