|Title:||Cougar (puma Concolor) Vocalization And Frequency Shift As A Playback Response [vocalização Da Onça-parda (puma Concolor) E Mudança De Frequência Como Resposta Ao Playback]|
de Araujo C.B.
|Abstract:||Recordings of cougar (Puma concolor) vocalizations are rare in the wild. We made two night recordings from the same individual. The first recording was spontaneous whereas the second was made after a playback emission (using a third party recording) allowing for comparisons. We measured the calls before and after playback stimuli using Raven software and noted that only the minimum fundamental frequency presented differences between calls. As fundamental frequency is closely related to body size, a frequency reduction may indicate territoriality engagement. Our recording seems to be the first held in the Brazilian wild. Little is known about cougar natural history and behavior, and our data suggest that acoustic communication may have an important role on the species intraspecific interactions.|
