- The Ruby-throated Hummingbird's range is from southern Canda and all of the U.S. east of the Great Plains; the only Hummingbird found in this area. They leave the North early in the fall, migrating to the Texas east coast, Mexico and Central America.
- Mostly nectar and insects. They get the nectar from red tubular flowers and also many other flowers. They are attracted to Hummingbird feeders for the sugar water.
- Site is usually in a tree or large shrub, about 10-20' above ground. Nest is built mostly by the female, and is a cup of plant down and plant fibers, held together by spider webs with the outside camouflaged with lichens and small leaves.
Hummingbirds may repair and reuse old nests.
- 2 eggs, white color. Incubation is by the female only, 11-16 days.
- The young are fed by the female inserting her bill deep in their throats and regurgitating food, including nectar and small insects. The nest stretches as the young grow. Young take their first flight at about 20-22 days. Usually 1-2 broods per season.
