Adaptation

One of the most striking things about wild animals is how easily they adapt to circumstances; a fancy term for this is behavioural plasticity. When I saw a group of Cheetal, apparently grazing in the mud next to the tidal creek, I was a little surprised. These animals are grazers, mostly dependent on grass.

In the featured photo you can see its whole body aligned along the tide line where fallen leaves have gathered. The strong reliance on a leafy diet struck me as an adaptation.

Another odd fact was that there were so many Cheetal near brackish water. These deer drink a lot of water, and I could not imagine them drinking sea water. It gradually dawned on me that there must be fresh water inland. Amar, our boatman, and Bijaya, our guide for the day, told us about ponds and wells which give sweet water. Around these there are also grassy meadows where we saw some deer.

We also saw small bands of rhesus monkeys on the muddy banks of creeks. Strangely, they seemed to be grazing in the mud. Bijaya said they were eating grass. Possibly, because they were certainly not picking up fallen leaves. I never came across them inside the forest, so I don’t know what fruits they eat. Mangrove fruits are unlikely fare for monkeys, but maybe they have adapted. Animal behaviour is so plastic that every niche yields delightful surprises.

I travel on work. When that gets too tiring then I relax by travelling for holidays. The holidays are pretty hectic, so I need to unwind by getting back home. But that means work.
