Hatching asynchrony and fitness in a neotropical seabird: second-hatched individuals from highly asynchronous broods are less fit but only during the rearing period.
The paper examines the effects of hatching asynchrony on fitness in Blue-footed boobies, finding that second-hatched nestlings from highly asynchronous broods have lower survival during rearing but no long-term fitness effects.
