The powerful, crescendoing, high-pitched, squeaky whistle in alternating low-and-high notes (typically low, high, low, high, very high, the last note being more of a squawk than a whistle) is the robin-chat's song, heard at varying volumes because it frequently moved location throughout its song. It was very loud and prolific. Can be heard at the very beginning, then almost continuously from 20" to 1'38" at waxing and waning volume (with superimposed bulbul chatter), then again from 1'43" to 2'14", and then very faintly thereafter. The vast majority of foreground chatter is from common bulbuls, and possibly some from sparrows. Notably, the in-flight chirps of a purple grenadier can be heard at 2'10" and 4'15". There are at least two other distant calls that I cannot readily identify by sound alone.

Detalles de la observación

Singing, fanning its tail, raising its bill skyward. It is flying between a few trees several hundred meters apart, it will stay in the near tree for about 2-3 minutes and be gone for 5-10.
