These less canopied tree are common in the NEERI campus near guest house and Eastern colony. The Asian Paradise Flycatcher mostly breed from May to July. These birds are monogamous and both share the duties of constructing the nest, incubating the eggs, and feeding and protecting the young.

A clutch usually consists of 3 - 4 eggs, which are incubated for about 21 - 23 days.

The cup nest is made out of twigs bound together with spider webs and is usually situated on the end of a low tree branch. Often, the nest is found close to active drongo nests, which helps to keep predators away from their own nests. Asian Paradise Flycatchers are quite noisy and their most common calls are described as sharpzweet's.
