The Gateway of India is full of pigeons, as you can see in this shot of birds on poles outside Taj and here with the kid chasing them. This place is somewhat like the Trafalgar Square in that sense. This reminds me that when I went to Trafalgar Square, I was really disappointed, as I couldn't find a single pigeon. On the other hand, Bombay has quite a few places where you can see lots and lots of pigeons including Kabootarkhana in Dadar and Flora Fountain.
