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.
Ruby-throated Hummingbird (Archilochus colubris) The Ruby-throated Hummingbird is by far the most common species that breeds in the eastern half of North America, although most states have sporadic Rufous sightings, and Bob and Martha Sargent have banded eight other hummingbird species as winter visitors to five southeastern states.
