In this experiment, we tested whether carrion crows (Corvus corone corone) learn to differentiate between calls of reliable or unreliable individuals. Crows were kept in an aviary that comprised four visually but not acoustically isolated compartments, separated by a central room. In an association phase, a dead crow placed in the central compartment was visible only to one of the four crow groups, whilst alert calls of a conspecific were played back. Therefore, these calls were reliable for that group, but unreliable for the three other groups. The procedure was repeated, using a different reliable caller for each group. In two test sessions, 1month apart, reliable and unreliable model individuals were played back, but no dead crow was presented. We quantified birds' attention behaviour and the number of vocalisations emitted. In the association phase, crows were more attentive towards the reliable compared with the unreliable stimuli and called more in response to reliable compared to unreliable individuals. In the test and repeat phase, attention behaviour did not differ between reliability conditions, but the pattern of vocal behaviour reversed, with crows calling less frequent when listening to reliable compared with unreliable calls. Vocal responses of crows suggest that they can discriminate between reliable and unreliable callers.
