One summer afternoon I heard a regular 'TUK TUK' sound I wondered from where it originated.I neared a Gulmohur tree and on a branch i saw a drilled hole and could see a bird head peeping out.It took me some time to figure out which species it was and with the help of my learned facebook friends I was able to figure out it was Coppersmith Barbet.Some facts about the bird are as follows-
The Coppersmith Barbet, Crimson-breasted Barbet or Coppersmith (Megalaima haemacephala), is a bird with crimson forehead and throat which is best known for its metronomic call that has been likened to a coppersmith striking metal with a hammer. It is a resident found in South Asia and parts of Southeast Asia. Like other barbets, they chisel out a hole inside a tree to build their nest. They are mainly fruit eating but will take insects.
