Ruby throated hummingbirds migrate from their summer habitats in the eastern and central United States to their wintering grounds in Central America and Mexico.
These tiny birds make the journey alone, with no flocking behavior observed.
Their migration patterns are influenced by the availability of nectar-rich flowers and insects, which provide them with the energy needed for their long journey.
Ruby throated hummingbirds typically migrate from August to November, with the peak migration period occurring in September.

Ruby-Throated Hummingbird Migration
Ruby-throated hummingbirds migrate to a winter range that stretches from southern Mexico to Panama, with some making a journey of over 2,000 miles.
Adult male ruby-throats are on the move by late July and early August, while most female and young ruby-throats start moving two to four weeks later.
In the eastern United States and southeastern Canada, ruby-throated hummingbirds are found almost throughout the summer, but during the coldest months, a few stay in the southeastern states.
Most ruby-throated hummingbirds don't fly straight north and south, but instead detour around the Gulf of Mexico.
Folks who live along the northern Gulf Coast can help hummingbirds prepare for their arduous journey by providing lots of nectar flowers and sugar-water feeders.
Ruby-throated hummingbirds arrive in Pennsylvania in late April and May, with males preceding females by a week or two.
In Illinois, ruby-throated hummingbirds return in April and May, seeking nectar from early blooming trees and shrubs as well as insects and spiders.
The ruby-throated hummingbird's migration is driven by instincts, not by the availability of food, so keeping a feeder up in fall won't stop them from leaving.
By the middle of May, ruby-throated hummingbirds have occupied almost all of their breeding range, which stretches from the northwestern states through western Canada to southern Alaska.
Migration Patterns
Ruby-throated hummingbirds arrive in Pennsylvania in late April and May, with males preceding females by a week or two.
Their migration path is guided by instincts rather than conscious choices, and they have no way of knowing what the weather is like up ahead.
In late summer or fall, ruby-throated hummingbirds usually leave their breeding grounds while food is still abundant, which is perfect timing to get energy for their journey southward by sipping nectar from jewelweed and cardinal flowers that bloom in August.
These tiny jewels are common nesters in Cook County woodlands and become more numerous in late summer and fall as they pass through on their way to their winter homes in Mexico and Central America.
Ruby-throated hummingbirds return to Illinois in April and May, seeking nectar from early blooming trees and shrubs as well as insects and spiders.
The female ruby-throated hummingbird builds a thimble-sized cup nest on a horizontal branch, adding grasses and spider webs, lining it with plant down and then covering the outside with lichens and dead leaves.
Hummingbirds Migrate
Ruby-throated hummingbirds migrate to a winter range that stretches from southern Mexico to Panama, a journey of over 2,000 miles.
Their instincts guide them to arrive at each stop along the way on dates when, in an average year, the coldest weather has passed and some flowers have started blooming.
Adult male ruby-throats are on the move by late July and early August, while most female and young ruby-throats start moving two to four weeks later.
Most ruby-throated hummingbirds don't fly straight north and south, instead moving toward the southwest in fall and toward the northeast in spring to detour around the Gulf of Mexico.
By the middle of May, they have occupied almost all of their breeding range, which stretches from the northwestern states through western Canada to southern Alaska.
High mountain meadows that had been snow-covered in spring will be filled with flowers by July and August, and rufous hummingbirds swarm there throughout late summer, gradually making their way back toward Mexico.

The ruby-throated hummingbird is the only species whose habitat is east of the Mississippi River, and they are found almost throughout the eastern United States and southeastern Canada in summer.
In spring, adult males may move north from the tropics by late February, and the peak arrival of ruby-throats in the southeastern states is mid-to-late April, with most not showing up in the Northeast until around the beginning of May.
Folks who live along the northern Gulf Coast can help hummingbirds prepare for their arduous journey by providing lots of nectar flowers and sugar-water feeders.
Rarely, a stray hummingbird stays far north in a snowy climate in winter, visiting a heated feeder, but that's due to faulty instincts – the feeder didn't keep the bird from going where it should have gone.
In August, when the jewelweed and cardinal flowers bloom, the ruby-throated hummingbird is migrating, getting energy for their journey southward by sipping nectar from the blossoms of these plants native to northern Illinois.
The ruby-throat is the only hummingbird to breed in eastern North America, and these tiny jewels are somewhat common nesters in Cook County woodlands, becoming more numerous in late summer and fall as they pass through on their way to their winter homes in Mexico and Central America.
