2. Las Vegas is home to a pigeon sanctuary where birds captured in buildings where they are not wanted can live out their days in the comfort of a chain-link cage. The founder of Nevada Pigeon Control, Nephi Oliva, estimates there are 500,000 pigeons in Las Vegas and wants to get rid of them humanely rather than killing them. So his business captures them and houses them in his sanctuary where they are cared for. He's hoping the City of Las Vegas will hire his company to control the pigeons, much as a dog catcher controls stray dogs.That would cost the city $8.2 million per year, according to the public utility rates on his firm's Web site.
