Fig. 1: Variation of avian care pattern in different forms across a breeding cycle.
From: Sex differences in avian parental care patterns vary across the breeding cycle
The results were based on 1533 species with full data on care pattern (‘Female care’, ‘Biparental care’, and ‘Male care’) across three forms of parental care: nest building, incubation, and offspring provisioning. Bars of different colors represent different categories of care patterns. Note that a few species of cooperative breeding were grouped into the ‘Biparental care’ category (N = 56 species in nest building, N = 48 in incubation, and N = 139 in offspring provisioning). Source data for producing this figure can be found in the file “Source Data”.
