“…There does, however, appear to be a differential response by sex whereby males preferentially reply to convergent 'chee' calls and females reply to both convergent and divergent calls (Balsby & Scarl, 2008). The fact that both sexes respond to convergent calls in a nonagonistic context suggests it has an affiliative function (Balsby & Scarl, 2008) that may facilitate the addressing of individuals (Balsby et al, 2012). There are also more subtle forms of vocal matching, with some primate species matching fine-scale features of a call type when calling together as a means of social affiliation (Mitani & Brandt, 1994;Sugiura, 1998) or to promote partner preferences (Biben et al, 1986).…”

“…Instead, convergent, divergent and variable patterns of call type similarity are observed in response to 'chee' call playbacks (Balsby & Bradbury, 2009).

“…However, this does not necessarily mean that crows are insensitive to sex in their communications. Previous studies in birds revealed that social interactions differed depending on sex combinationsfor example, higher aggression between males in largebilled crows, as well as other corvids [12,13,21], and strong responses to contact calls of opposite-sex individuals in orange-fronted conures (Aratinga canicularis) [22]. These sex effects on social interactions suggest that responses of subjects to the played-back calls might be influenced by the combination of the stimulus and the subject sexes.…”

Crows cross-modally recognize group members but not non-group members

Recognizing other individuals by integrating different sensory modalities is a crucial ability of social animals, including humans. Although cross-modal individual recognition has been demonstrated in mammals, the extent of its use by birds remains unknown. Herein, we report the first evidence of cross-modal recognition of group members by a highly social bird, the large-billed crow (Corvus macrorhynchos). A cross-modal expectancy violation paradigm was used to test whether crows were sensitive to identity congruence between visual presentation of a group member and the subsequent playback of a contact call. Crows looked more rapidly and for a longer duration when the visual and auditory stimuli were incongruent than when congruent. Moreover, these responses were not observed with non-group member stimuli. These results indicate that crows spontaneously associate visual and auditory information of group members but not of non-group members, which is a demonstration of cross-modal audiovisual recognition of group members in birds.

“…These birds may simply need greater motivation in order to be able to vocalize what they heard in spite of instances that they can readily mimic even instrumental sounds or artificial noises occasionally (Gramza, 1970). Several playback experiments in other two parrot species (Balsby & Scarl, 2008;Scarl & Bradbury, 2009;Vehrencamp et al, 2003) suggests that not only direct social interaction but other contexts such as like a territorial protection, may also play an important role for vocal imitation. Perhaps constructing some of these more "natural contexts" in the experimental domain may be able to identify the key components that facilitate vocal imitation in budgerigars.…”

-Budgerigars were trained by operant conditioning to produce contact calls immediately after hearing a stimulus contact call. In Experiments 1 and 2, playback stimuli were chosen from two different contact call classes from the bird's repertoire. Once this task was learned, the birds were then tested with other probe stimulus calls from its repertoire, which differed from the original calls drawn from the two classes. Birds failed to mimic the probe stimuli but instead produced one of the two call classes as in the training sessions, showing that birds learned that each stimulus call served as a discriminative stimulus but not as a vocal template for imitation. In Experiment 3, birds were then trained with stimulus calls falling along a 24-step acoustic gradient which varied between the two sounds representing the two contact call categories. As before, birds obtained a reward when the bird's vocalization matched that of the stimulus above a criterion level. Since the first step and the last step in the gradient were the birds' original contact calls, these two patterns were easily matched. Intermediate contact calls in the gradient were much harder for the birds to match. After extensive training, one bird learned to produce contact calls that had only a modest similarity to the intermediate contact calls along the gradient. In spite of remarkable vocal plasticity under natural conditions, operant conditioning methods with budgerigars, even after extensive training and rigorous control of vocal discriminative stimuli, failed to show vocal learning.
