Shiny cowbird Molothrus bonariensis egg size and chick growth vary between two hosts that differ markedly in body size

Mostrar todas las versiones(2)

In birds, egg size affects chick growth and survival and it is an important component of reproductive success. The shiny cowbird Molothrus bonariensis is an extreme generalist brood parasite that uses hosts with a wide range of body masses. Survival of cowbird chicks decreases with host body mass, a...
