From: An integrative measure of cognitive performance, but not individual task performance, is linked to male reproductive output in budgerigars

Figure 2

Males with higher composite cognitive scores sire more nestlings. (a) Relationship between male composite cognitive score and number of nestlings sired (N = 30). (b) Relationship between male composite cognitive score and number of extra-pair nestlings. Only males that were paired during the breeding phase were included (N = 15). Shaded areas represent 95% confidence intervals from the generalized linear models. (c) A female budgerigar engaged in an extra-pair copulation next to her social mate (left).
