I never had the opportunity to see the other bird and find out its sex. But it sounds just like the first one.
Is it actually communicating with a male bird? What is the known reason if so?
1 The reply calls (to be found around 0:29) in the video are really low.
- A singing male bird also gives desperate accelerated calls when mimicked.
- Its breeding season has just begun in India and this communication can be heard.
