Chicago Bans Pet Pigeons

Chicago has banned pet pigeons. This specifically effects those who are enthusiasts of pigeon racing:

A federal appeals court has upheld the city's ban on pet racing pigeons, rejecting claims by some enthusiasts that the ordinance is unconstitutional.

The ban makes Chicago the only large U.S. city that outlaws pet pigeons, according to the American Racing Pigeon Union.

The pigeons coo excessively and scatter feathers and droppings, proponents of the ban said.

How this has any significance to the thousands of wild free-range pigeons that inhabit the city, I am unable to determine. However, based on their past record in dealing with gun control, I'm sure they know what they are doing.
