In winter, when the food and water supply stored in their nest is exhausted, some of the ants called workers are sent to find new sources and replenish the colonyâs supplies. The pests feed on: 1  pet food, 2  live and dead insects, 3  and almost anything that people eat.
Where do they live? Ruby-throated hummingbirds are found in North and Central America. They breed throughout the eastern United States, east of the 100th meridian. They also breed in southern Canada where there is eastern and mixed deciduous forest. The species spends winters in southern Mexico, Central America (as far south as Costa Rica), and in the West Indies.
Like their neighbors, they assumed the ruby-throated hummingbirds that summered in their magnolia and live oak-filled yard were about to head south to the Tropics. But a funny thing happened about ten years ago: âI started hearing hummingbirds during the winter,â says Annabeth.
