Trade‐offs in avian parental care: a review of theory and meta‐analysis of brood size manipulations
Biological Reviews, EarlyView.ABSTRACT The selective forces shaping parental care have been studied for over 50 years. While theoretical and experimental work has yielded qualitative progress, the large body of empirical work testing predictions about parental investment based on life‐history trade‐offs has yet to be synthesized.
