At the core of the suite of adaptive hatching hypotheses advanced to explain asynchronous hatching in birds is the assumption that if food is not limited then all the hatchlings will develop normally to adulthood. In this study Brown-headed Parr[...]

Theoretical criteria have been advanced to describe conditions under which avian species are able to recognise the voices of neighbours, thereby reducing physical conflict. Namely, that the signal should be sufficiently stereotyped to allow spec[...]
