NOTES: (Background Sounds: Tropicbird distantly overhead, Bulbuls introduced P. jocosus; Number of Animals and Sex: adult males and females; Range Status: highly endangered; Stimulus for Sound: natural, then playback own song) HPF 220. The individuals 2 mostly [a male and female] foraging at a Trochetia uniflora flowers the "purring" grating call was uttered while the pair were perched close gleaning and also preening. They also appeared to "close eyes" and "doze". There is a P. jocosus heard with them but their "pit-calls" are clear. The initial p-calls are natural - then playback was used. Annotations are included. I was using playback with care as their population density was so low it was difficult to get any vocalizations to record. On one occasion as they also gleaned insects on /from under/over the Sideroxylon puberulum the "beating" of a small caterpillar can be heard. Flight calls as well as pit contact calls are heard. Field annotations included. Other Behaviors: Mate, Advertise.
