Abstract

In many bird species, females mate with males other than their social partner, a behavior considered to be beneficial in terms of inbreeding avoidance, or to attract additional care of offspring from EP males. In noisy miners, we show that although 27% of broods contained EP offspring, EP males did not provide help to those broods. Moreover, we did not find evidence that this behavior functions as a mechanism to avoid inbreeding in this species.
