"Lucky looked out, towards the Statue of Liberty. Beyond it a cluster of jets were circling and stacking up for landing at La Guardia. There was a nest on the ledge outside Black's window, and a pigeon - presumably one of a pair - was minding it. She remembered the pigeons outside her window at the Fairdeal office in Bombay acting this way." ( p. 217)
Pigeons have been cooing outside my window for as long as I remember. While birds are essential creatures, they can be quite annoying, especially when they gurgle incessantly all day long, make nests in the air -conditioners positioned outside and more importantly cast off their feathers which get tangled up in the houseplants sunning themselves in my balcony.
This is largely because there are several spots in Mumbai which are reserved for feeding pigeons like the famous "Kabutarkhana" at Dadar.
