Proximate mechanisms of detecting nut properties in a wild population of Mexican Jays (Aphelocoma ultramarina)

Abstract

In contrast to extensive research on optimal foraging in birds, the proximate mechanisms by which birds estimate the properties of nuts or seeds have not been well studied. Using slow-motion video-recording and experiments with modified peanuts presented to birds in their natural habitat, we explored these issues in a wild population of the Mexican Jay… (More)
