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.

Just yesterday, I spotted the first hummingbird of the season at the nectar feeder hung under the eaves of my back porch.I was beginning to wonder where the little guys were.Generally, I fill and hang a feeder around April 30 and quite promptly have visitors.ust yesterday, I spotted the first hummingbird of the season at the nectar feeder hung under the eaves of my back porch.
