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.
Similarly, the western populations migrate annually between regions west of the Rocky Mountains including northern Canada and overwintering sites at the coast of California. Monarchs also perform small distance migrations in Australia and New Zealand. There are also some populations, for instance in Florida and the Caribbean, that do not migrate. Recently discovered overwintering sites have been identified in Arizona and northern Florida.
