Vocal communication serves an important role in driving animals' social interactions and ultimately their survival. However, natural vocal behavior can erode in human care. Determining if animals in conservation breeding programs exhibit and respond appropriately to species-specific vocalizations is therefore important for ensuring their survival post-release. We tested whether endangered 'alala (Corvus hawaiiensis), which are extinct in nature, have retained their natural responses to survival-relevant vocal calls. We conducted our studies on breeding populations derived from a small number of founding 'alala maintained in human care since their extinction in the wild in 2002. We presented pairs of 'alala with alarm, territorial intrusion, and two types of control playback calls (a non-threatening territorial maintenance call and a novel heterospecific call). 'Alala were significantly more likely to approach the speaker following alarm call playback than other call types, and were more likely to respond to territorial intrusion calls with the same aggressive territorial calls. Males were more likely to make these aggressive calls than females, mirroring their roles in territory defense. We also found individual consistency in the level of vocal behavior response across all call types, indicating that some individuals are more vocal than others. These results are encouraging, showing that 'alala exhibit relevant, species-specific behaviors despite generations under human care. It does illustrate, however, that all individuals do not respond uniformly, so vocal response may be an important factor to consider in determining the release suitability of individuals.

AbstractThe communicative functions of sound production during aggressive activity were studied by playing back the choking, trumpeting, mew, alarm and yelp calls to Larus glaucescens reacting aggressively to a mirror placed within its territory or by measuring the latency of attack on a stuffed model mounted in one of the display postures involved in aggressive activity. Differences between the experimental period with sound playback, and the control period with no sound playback were analyzed statistically by means of paired comparisons t-tests. As the result of these experiments the following conclusions were reached: I. The choking sound would inhibit the entrance of an intruder when produced by the territorial bird, but when produced by the intruder would stimulate the aggressive activity of the territorial resident. 2. The mew call functions similarly to the choking call but probably represents a somewhat lesser degree of aggressiveness. 3. The trumpeting call hastens an attack by a bird outside of its territory when produced within its territory and also stimulates aggressive activity of a bird within its territory, when produced by an intruder. 4. The alarm call inhibits aggressive activity, although it is not a usual part of aggressive activity. 5. The yelp call does not effect aggressive activity.
