Abstract

In territorial songbirds, both parental and territory qualities influence resource allocation to offspring, but their relative contributions are unclear. We experimentally decoupled these 2 factors, allowing us to examine the contribution of territory quality, alone, to investment in offspring. We showed that territory quality influences provisioning of nestlings through a prenatal effect on the composition of eggs laid, rather than a postnatal effect of the quality of territory on which provisioning occurred.
