Sex‐related variation in survival is common birds and, as it influences effective population size and growth, important for conservation species management. Here we assessed incubation behaviour sex‐related a threatened sexually monomorphic shorebird, the S t H elena P lover C haradrius sanctaehelenae . Males incubated at night, period of highest activity cats, which are likely to be predators breeding birds. In spite behavioural differences between sexes, adult was not significantly different males females, suggesting that sex‐biased need lead survival, thus may impact upon sex ratio.
