Tame the deer.
And, if on the busy roads,amidst all the traffic, you actually spot a koel being chased by the crow..then yes, the birds have adjusted to urban life.
As have those sambars. who wandered out of the protected national park, to the vast roads of the western express highway.Their predators are now in the form of speeding vehicles, which might just knock them over. Perhaps, the government should really allow the deer and their like to live in some of our public and private parks. They might attract the monkeys and the birds and perhaps, Mumbai might just become more verdant in the future. Provided that people don’t kill them for their meat, or their shiny coats, or their hidden treasure of kasturi.
If the greedy make a pact not to kill them, it might be a good idea to tame them instead.
