Due to their greater abundance in cities than most other birds, feral pigeons support many peregrine populations as a staple food source, especially in urban settings.
The peregrine is a highly successful example of urban wildlife in much of its range, taking advantage of tall buildings as nest sites, and an abundance of prey such as pigeons and ducks.

DDT really did a number on urban avian predators; it gets concentrated up the food chain and then the eggs of birds become too fragile.

And it’s funny to me to have an environmental initiative largely motivated by “something needs to be killing all these fucking pigeons.”
