No experimental evidence for local competition in the nestling phase as a driving force for density-dependent avian clutch size [PDF]

, 2009
1. In birds, local competition for food between pairs during the nestling phase may affect nestling growth and survival. A decrease in clutch size with an increase in breeding density could be an adaptive response to this competition.
