One concerns speech perception: is the ability to distinguish specific speech sound contrasts strictly human or also present in birds? The other one concerns the ability for detecting and learning particular grammar rules, using the paradigm of artificial grammars: what is the level of complexity that birds can cope with? These findings in birds will be related to those obtained in other animal species.
