“More frugivory observations for this Ruby-cheeked Sunbird (Chalcoparia singalensis interposita) with both male and female feeding on Ficus benjamin fruit (above, below).
“They have this curious habit of calling almost constantly while in the feeding tree. A sharp call, once every 2 seconds.
“If not for the call they are hard to spot in this tree with many other birds and their preference for the dense undergrowth.“An edited recording of calls made by the female (above) with sonogram and waveform of call below. The calls have been rendered by various authors in different forms.”
