What happens when those pigeons get eaten by other animals? Will the drugs have an effect on them? Could the drugs end up in the human food chain, or end up in the water, out to sea?
If we release predators, what says that they will understand how to balance according to human needs? Will the predator population explode and completely decimate the "pest" population? Could the predator possibly start predating on beneficial organisms once the "pest" population gets low?
I don't understand why humans disrupt STABLE ecosystems, and then get their panties in a knot because ecosystem diversity takes a dip. Something as simple as disposing of your garbage properly and a few building design changes can solve this problem.
Two points here that you are not considering:
1) Rock doves also known as common pigeons are an introduced species. they are feral domestics.
2) The predators that are being released in these metro areas are native to all of N. America. Peregrine falcons and and Red Tailed hawks that were once very common in the areas they are being released into.
The cities that have released the raptors are showing great results, the birds are finding the tall buildings to be excelllent nest sites and the food supply is plentiful.
Pigeon numbers have dropped in those areas, and the raptor populations are on the rise.
