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.
In Spring, the exciting annual North American hummingbird migration begins! These gorgeous birds travel from their winter homes in South or Central America and Mexico to the north. In Fall, hummingbirds will migrate to the warmer climates of South or Central America and Mexico where their is also an abundant food source. However, not all hummingbirds migrate each year. Some will spend the Winter along the western coast of North America.
