Differences in breeding success among neighbouring streaked shearwater subcolonies correlate with egg size and quality of parental care

Abstract:

To identify drivers of local variation in breeding success in colonial seabirds, we studied the role of breeding phenology and parental quality on the breeding performance of two neighbouring subcolonies of streaked shearwaters Calonectris leucomelas, with similar habitat but different success. Egg dimension and parental quality during incubation, but not phenology, predicted hatching success. Birds on the low-success colony laid smaller eggs, reared smaller chicks and neglected eggs more fre...
