Male–male vocal interactions in a territorial neotropical quail: which song characteristics predict a territorial male's response?

摘要: Males singing within their territories can change song characteristics in order to interact with conspecifics; males may respond territorial intrusions by vocalizing, approaching the intruder and/or displaying. I studied male–male interactions quantifying vocal and behavioural responses of male spot-bellied bobwhites (Colinus leucopogon) toward playback conspecific songs. Male depended on quality male's relative stimulus. In this species who sang songs higher peak low frequency, longer duration, lower rate were less responsive simulated intrusions. Spot-bellied bobwhite that response increased frequencies pre-playback song, a behaviour related dominance other species. approached speaker songs, characteristic associated aggression or motivation fight bird The results experiment suggest according predict may, therefore, play an important role interactions.
