Whether parental effort can be negotiated between partners over ecological time and adjusted across different contexts is not well understood. We manipulated male extra-pair copulation (EPC) opportunity in captive zebra finches, Taeniopygia guttata, to test whether males adjust incubation effort to the mating context and to examine how females respond to their partner’s effort. Birds without previous breeding experience were paired randomly and bred with the same partner twice. In the first… CONTINUE READING
