Otoacoustic emissions but not behavioral measurements predict cochlear nerve frequency tuning in an avian vocal communication specialist [PDF]
eLifeFrequency analysis by the cochlea forms a key foundation for all subsequent auditory processing. Stimulus-frequency otoacoustic emissions (SFOAEs) are a potentially powerful alternative to traditional behavioral experiments for estimating cochlear tuning

Egg retrieval in ground-nesting cuckoo hosts: can two species of buntings accurately identify and retrieve their own eggs? [PDF]
Animal CognitionEgg retrieval in birds may help ensure the survival of eggs and improve reproductive success. However, with the risk of brood parasitism, for ground-nesting or cavity-nesting bird hosts, there is a significant reproductive cost and thus a reduction in ...

Common cuckoo eggs are more resistant to puncture by the host [PDF]
International Journal for Parasitology: Parasites and WildlifeThe puncture resistance hypothesis suggests that thick-shelled eggs of parasitic birds can resist puncture-ejection by the host. However, few experiments have yet been conducted to test this hypothesis in terms of natural host behavior (e.g., pecking at ...
