The Ruby-throated hummingbirds like to move straight and fast, but sometimes they also hover around the feeders to get the nectar and can adjust their positions accordingly. The tube-shaped nectar flowers are their favorite flowers, and they defend their food sources against the other hummingbirds. They also like to get tiny insects from air or from spider webs to fulfill their protein needs. You can locate them on the feeders and flowers as they like to get the nectar throughout the day to survive the colder nights by going into the torpor state.


The Ruby-throated hummingbird is a migratory bird that spends its life in the different parts of Central America, Mexico, Florida, and Canada. Mostly they spend their breeding season in Eastern United States, South-central, and Southeastern Canada. They build their nests in pine forests at the forest’s edges, orchards, and gardens. They prefer the protected locations in the shrubs, as they have the longest breeding range as compared to all the other species of hummingbirds. The female Ruby-throated hummingbirds need these nests throughout their breeding season. So, you can locate their nests in the open woodlands, forest edges, meadows, grasslands, parks, gardens, and backyards.


Red and the orange tubular nectar flowers are the favorite flowers of the Ruby-throated hummingbirds, which include the trumpet creeper, cardinal flower, honeysuckle, jewelweed, buckeye, bee-balm, and red morning glory. They also like to pick the insects from air and spider webs, which include mosquitoes, gnats, fruit flies, and small bees. Sometimes they also like to pick the cater pills and aphids from the leaves. You can also offer them the artificial nectar in hummingbird feeders. Take four parts of water and one part of sugar and mix it well before providing it to hummingbirds.

Their nests are usually slender or on the tree branches such as oak, hornbeam, birch, poplar, or hackberry. Rarely, their nests are also seen on chain loops, wire, and extension cords. They built their thimble-sized nests on the branches. They use their neck and chest to perfectly shape the nests. Their nest is usually built-in 6 to 10 days and has 2 inches diameter with 1 inches depth. The female laid 1 to 3 eggs, which are very tiny, white, and weighted only half a gram. The incubation period of the eggs is 12 to 14 days, with the nesting period of 18 to 22 days.


The Ruby-throated hummingbirds are migratory birds and can be located in the different parts of the United States, Mexico, and Canada.

They start their spring migration in January and arrive at their breeding grounds between the end of February and early April. Some of the Ruby-throated hummingbirds travel to South to Central Mexico, west Panama, or Caribbean islands during their migration.
