Quick Answer. Most hummingbirds in America and Canada spend the winter in Mexico or South America before migrating to their breeding ground in southern U.S. as early as February or the first week of March. Some South American hummingbird species also travel north to the tropics during the southern winter.
Most hummingbirds live in a warm climate and do not migrate, but the ones that do may eat much more than usual and stock up on fat, like most migratory birds do. But, since they have such a high metabolism, this may not be possible.
