The Mimicry artist

In last post, we got introduced to Drongos. In this post I will introduce you to their amazing mimicking ability. These amazing birds mimic other species and gather almost quarter of their daily food by mimicking other species. It was observed that these birds make false alarms so that other animals drop their kill and run which gives a window for these birds to swoop in. One of the study claims to have observed them making almost 51 different calls or various species.

You can watch one of such observations here

Drongos are insectivorous birds which are usually found in open forests or bush. Most of them are black or dark grey  and some with metallic tints. They have long forked tails which is more significant in Asian species. 

Drongo is slang for idiot in Australia probably referring to the behavior of only kind of drongo found there i.e. Spangled drongo.
