Yellow Vented Bulbul’s classical territorial call

posted in: Territorial, Vocalisation | 1

“The Yellow Vented Bulbuls (Pycnonotus goiavier analis) have many calls that they use for a variety of purposes. One of the calls is unique in that it is associated with an ‘out spreading’ (lifting) of the wings and tail. This particular call is not easy to capture as it is usually given once at a time (i.e. not repeated immediately). It is my observation that the male is the one that delivers this call, by watching the different roles the birds play (even though the sexes are largely indistinguishable). The male uses this call to tell other Yellow Vented Bulbuls that this is their (his & partner’s) territory – a territorial call.

“I finally managed to document the posture of the call on camera (the audio recordings were not a problem, as have done recordings in the past). I was back for lunch yesterday and had the camera out in the garden were we eat most meals. There were 5-6 Yellow Vented Bulbuls in our fruiting Neem Tree and our resident pair were distressed trying to protect their home – chasing visiting Yellow Vented Bulbuls here and there. Finally the male stopped to give this ‘trumpet’ call to declare his territory. I was just fortunate I was holding the camera and
watching with it.

“…An older recoding of the call HERE. In the audio recording I have duplicated the call twice to give you an opportunity to hear it better.”
