Ruby-cheeked Sunbird – calls

posted in: birds, Vocalisation | 0

These are from call recordings of the Ruby-cheeked Sunbird (Chalcoparia singalensis singalensismade). The sunbird was a self-feeding, immature male I posted from 17th August 2020. Different sources have described song and calls in different ways with trills, chirps and a variety of other notes. I have heard much variation in the calls and songs. Some sonograms and waveforms of calls:

The above shows one variety of call use. These notes have some similarity in the sonogram but are used in a variety of different ways. The first section shows single notes, 0.2 seconds long. These can be used as coupled notes (2-5 notes) in a run (second section). Finally the same call can be extended (up to 0.4 seconds) to give a longer drawn-out call or slurred note.

The above shows a group of sharper, briefer (0.1 seconds), higher frequency calls that are often used in runs of 3-6 notes.

All these calls can be heard in this recording:
