Parakeets colony nests in New York

These birds of a feather flock to find food under odd weather conditions in their chosen home. It's late March, and the blanket of snow is as unsual for New York as their story, which starts in a foreign country. This is Green-Wood cemetery in Brooklyn, almost 500-acres of private burial ground where a colony of Monk parakeets rule the land.Nobody knows exactly how or when these Argentinean birds ended up here, says local parrot watcher Stephen Baldwin.
