Breeding success, but not reproductive investment, increases with females age in Tachycineta leucopyga (Chilean Swallows)

Abstract

This dataset contains information on reproductive investment—estimated by clutch size and provisioning rates to nestlings—and breeding success—estimated by number of fledglings, hatching success, and fledging success—in the Chilean Swallow (Tachycineta leucopyga). The data were collected from breeding nests monitored during the study. The dataset includes the variables used to estimate reproductive performance and breeding outcomes.
