The birds you're most likely to see while strolling around a city are pigeons. In the wild, they typically eat grains and seeds, but in New York City, you might see them eating discarded popcorn, French fries — just about anything dropped by careless pedestrians.
Pigeons have round bodies, short necks, and small beaks. These common birds are related to doves. Their feathers are mostly gray, but if you look closely at a pigeon you'll notice shades of green, blue, and white. The distinction between pigeons and doves is vague — often, the word dove simply means an all-white pigeon, though sometimes it refers to a smaller variety of bird. Pigeon is French, from a Latin root, pipio, "young, chirping bird."
