In the spirit of Evo-Devo, Evo- Mecho, the integration of function and mechanism in the study of animal behaviour, is gathering steam. This is especially true with respect to cognitive mechanisms. But the meta-theoretical issues within the field of cognitive psychology may limit the effectiveness of applying that field’s current theories and perspectives to investigations of adaptive animal behaviour. I will present some of my own attempts to apply cognitive theory to foraging ecology - investigating the cognitive mechanisms that underpin foraging in the noisy miner bird for foods with different natural distributions. I will suggest that Evo-Mecho, if it is to succeed, may need to become the impetus for a new brand of ‘cognitive ecology'.
