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

Abstract Cognitive abilities such as learning and memory are key for survival and reproduction. Individuals with high cognitive abilities may be more successful at attracting mates and producing offspring. However, empirical tests of and evidence supporting this hypothesis remain scarce. We measured...
