Spring 2021 Hummingbird Migration Map & Sightings


The Urge of Migrate

Maps of Previous Migration Years

Many hummingbirds spend the winter in Central America or Mexico, and migrate north to their breeding grounds in the southern United States as early as February, and to areas further north later in the spring.

Hummingbirds fly by day when nectar sources such as flowers are more abundant. Flying low allows the birds to see, and stop at, food supplies along the way. They are also experts at using tail winds to help reach their destination faster and by consuming less energy and body fat. Research indicates a hummingbird can travel as much as 23 miles in one day.

During migration, a hummingbird's heart beats up to 1,260 times a minute, and its wings flap 15 to 80 times a second. To support this high energy level, a hummingbird will typically gain 25-40% of their body weight before they start migration in order to make the long trek over land, and water.

The first arrivals in spring are usually males. Some, however, do not migrate, in areas like California and the upper Pacific coast, the southern parts of the Gulf of Mexico states, and some along the southern Atlantic Ocean areas.

The Final 2021 Migration Map

We monitor the spring hummingbird migration from early January to mid-May of each year, with the help of our viewers as they submit their first hummingbird sightings in their areas.

Now that hummingbirds have reached their northernmost breeding grounds in the Canadian provinces, we have ended our mapping project for the year.

Shown below is our final map of hummingbird sightings in 2021 across the U.S. and Canada, as reported by our website viewers. In 2021 we received over 12,000 "first sighting reports". The map has been viewed over 5,000,000 times !

With the spring migration complete, we are no longer posting sightings to our 2021 map.

Map of Breeding Ranges of Dominant Hummingbird Species in North America

The map below shows the approximate breeding ranges of four major hummingbird species in North America: Rufous, Anna's, Black-chinned and Ruby-throated. Of course actual breeding areas vary by year depending on weather-related conditions and other environmental factors.

More About the Spring Hummingbird Migration

During migration, a hummingbird's heart beats up to 1,260 times a minute, and its wings flap 15 to 80 times a second. To support this high energy level, a hummingbird will typically gain 25-40% of their body weight before they start migration in order to make the long trek over land, and water. They fly alone, often on the same path they have flown earlier in their life. Young hummingbirds must navigate without parental guidance.

Hummingbirds fly by day when nectar sources such as flowers are more abundant. Flying low allows the birds to see, and stop at, food supplies along the way. They are also experts at using tail winds to help reach their destination faster and by consuming less energy and body fat. Research indicates a hummingbird can travel as much as 23 miles in one day.

Strong cold fronts moving south over the Gulf of Mexico make flying difficult as the birds deal with headwinds and heavy rain, over long distances with no shelter. Food is non-existent over the open waters.

The Fall Hummingbird Migration

By August and September, hummingbirds are moving south, refueling their bodies in the early morning, traveling midday, and foraging again in the late afternoon to maintain their body weight.

Ruby-throats gather in Florida, Louisiana and along the South Texas coast in September in preparation for the final push to the south, either over the Gulf of Mexico or via an overland route through Mexico. The Rufous hummingbirds head south, most via the eastern range of the Rocky Mountains.
