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.
Migration Status. Rufous Hummingbirds winter in Mexico and south Texas. In recent years, they have been wintering more frequently in the gulf states and have attempted to winter in the northeast. In the spring, they migrate up the Pacific Coast, reaching as far north as south-central Alaska, and they are thus the northernmost breeding hummingbird.
