The brainfever bird

I received this lovely portfolio from Mr Ramanan, and had to put it here, for posterity.

The brainfever bird, heard so commonly, elusive to sight.

Like the Asian Koel, it is also a brood parasite, and also has a maddening, repetitive call, heard in the monsoons. They lay their eggs in babbler nests.

The story goes that during the hot summers and just as the monsoons set in, the call of these birds used to drive some of the colonial Brits to madness, as they battled delirium and malaria, and the bird's incessant calling!

Freedom fighters of a sort?!

According to Wikipedia,
Common Hawk-Cuckoos feed mainly on insects and are specialised feeders that can handle hairy caterpillars. Caterpillar guts often contain toxins and like many cuckoos they remove the guts by pressing the caterpillar and rubbing it on a branch before swallowing it. The hairs are swallowed with the caterpillar and are separated in the stomach and regurgitated as a pellet.

Sunday activity

New Beach Road, Thiruvanmyur was the sight of a Nizhal combo plan - tree walk plus free-the-tree (FTC) activity!

We were thirty of us who assembled at 7 am on a Sunday morning (a feat in itself I thought!) at the eastern end of the road that runs east-west, perpendicular to the Thiruvanmyur beach. Its a road that I walk on regularly, but I had assumed there were some five varieties of trees. Can you imagine we identified 23?!! I was quite ashamed with my previous lack-of-"awareness" about the road.

There were a lot of children and soon they were more interested in the FTC than in the "know-your-trees" walk. So, it became that the moms were asking questions about the trees while the men and children busied themselves with claw hammers, stools and pliers! It is illegal to put up boards on the trees, and as citizens we are well within our rights to remove them. Also, they harm the trees, and do have an affect on their health in the long run. After all, isn't the bark a protective skin for the tree? Everytime a nail is driven into the bark, we are creating a wound. Once we removed the nails, we applied some turmeric paste to these "wounds", and hope that is sufficient for the bark to heal.

At the end of an hour we had removed all the boards (save one, which was beyond our reach), and thanks to Arti and her aunt we were all treated to yelaneer for our efforts! It was Arti who mooted the idea in the first place, so hats off to her. Things we could do to follow up:
  • Plant some more trees close to the eastern end. We need to identify trees like sea grapes, Punnai, Pongam, which will withstand the salty air.
  • Talk to our councillor about removing some of the concrete that is choking the base of the trees
  • Ensure that the trees remain board-free.
It was very nice to walk in the evening and see the trees all free of boards!
