Now that hummingbirds have reached their northernmost breeding grounds in the Canadian provinces, we have ended our mapping project for 2022. We typically track the spring hummingbird migration from late-January to mid- May of each year, with the help of our viewers as they submit their first hummingbird sightings in their areas. 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 first arrivals in spring are usually males.
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. Research indicates a hummingbird can travel as much as 23 miles in one day.ĭuring migration, a hummingbird's heart beats up to 1,260 times a minute, and its wings flap 15 to 80 times a second. They are also experts at using tail winds to help reach their destination faster and by consuming less energy and body fat. Flying low allows the birds to see, and stop at, food supplies along the way.
Hummingbirds fly by day when nectar sources such as flowers are more abundant. 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.
