Even though I like birds, I have picked up an aversion for pigeons. They are a menace, because they don't setup proper nests in trees and just come and setup their home inside AC vents, window sills where ever they find space. They kill eco-system of other birds like sparrows, munias, bulbuls by bullying them and chasing them out from balcony. And god they multiply their numbers like hell that before you realist the whole place stinks with their poops.
Still appreciate you did the right thing :)
