He also suggested appointing a "pigeon czar" to orchestrate the fight, a plan that has ruffled the feathers of animal lovers.

"Cities are lifeless places. People don't appreciate the fact that we have some wildlife," said Al Streit, director of The Pigeon People, an organization that rescues injured birds.

Felder said he doesn't expect to rid the city of pigeons but that it was time to combat what he called a public health hazard.

Felder said pigeons and their droppings are host to several severe communicable diseases, though a report released by his office noted that cases "are rare and the threat is often exaggerated."

London has outlawed feeding pigeons in Trafalgar Square and brought in trained hawks to kill them. But pigeons still flock to the square, and Mayor Ken Livingston has come under fire for the program's high cost.

Venice is trying to stop the sale of bird seed in St. Mark's Square and prevent pigeons from chipping away at marble statues and buildings. Licensed bird feed sellers do not want to go and animal rights activists have also expressed concern.

This summer, Los Angeles said it would introduce a pigeon contraceptive called OvoControl P to reduce the population.

"The fact is that people have been disgusted and annoyed," said Felder, adding that he frequently dodges pigeon droppings at his Brooklyn subway station. "I might as well say that I'm sick and tired of it."

This isn't the first time New York City has tried to control its pigeon population. In 2003, a hawk was briefly employed to scare pigeons in a Manhattan park but the program was abandoned a few months later after the hawk attacked a Chihuahua.
