Among the most exciting spring migrants are the hummingbirds! These tiny, truly remarkable creatures are all-American birds. They exist only in South, Central, and North America—nowhere else in the world. Enjoy these fascinating hummingbird facts …

What Is a Hummingbird’s Size?

These diminutive birds weigh only about 4 grams—or .141 ounce! That’s tiny! For comparison, a U.S. penny weighs 2.5 grams. The egg of a hummingbird weighs just 0.4 gram to 2.4 grams. A newly hatched bird is just 0.62 gram. However, when it’s time to migrate, hummers pack on the grams for the long trip—sometimes doubling their weight.

They are among the smallest birds, too, with most species measuring 3 to 5 inches long. The smallest bird, the bee hummingbird, is only 2 inches long—and weighs less than 2 grams.

How Fast Do Hummingbirds Beat Their Wings?

Hummingbirds, with their iridescent colors and fairly short wings, beat their wings as fast as 80 times per second! They do NOT flap their wings—they rotate them in a figure 8, which makes it even more remarkable! In fact, their name comes from the fact that they flap their wings so fast that they make a humming noise. Hummingbirds can hover, stop instantly, and fly in different directions (even upside down) with exquisite control.

Where Do Hummingbirds Live?

Hummingbirds evolved in the equatorial tropics. In the spring, 21 species fly thousands of miles northward from Mexico, Costa Rica, and other southern places to visit the United States and Canada. In the fall, they return to their southern homes. 

In North America, the greatest number and variety of hummingbirds can be found in western areas of the United States and as far north as Alaska. Only the Ruby-throated Hummingbird is found east of the Mississippi. The birds also visit southern Canada, especially British Columbia, Alberta, and Nova Scotia.

Many of these birds make round-trip migration flights of more than 1,600 kilometers (995 miles). Although hummingbirds usually weigh less than an ounce, these tiny birds have a lot of energy. When the wind blows in the direction in which they are flying, they can travel up to 50 mph.

Some fly nonstop across the Gulf of Mexico in spring and autumn. Cornell University scientists report that in preparation for such flights, they double their body weight with nectar and insects. They burn all additional weight when crossing the Gulf of Mexico.  They consume 10 times per gram of muscle tissue than the most elite among human athletes, marathoners and cross-country skiers.

When hummingbirds are arriving in the north, they are sometimes confronted with unusually cold weather and will enter into a hypothermic torpor to survive.

How Fast Is a Hummingbird’s Heart Rate?

Hummingbirds have a very high metabolic rate, with heart rate of 1,260 beats per minute and breaths of 250 times per minute. 

The long flights and wing-beating can make a hummingbird weary. As often as every 15 minutes, they look for a place to rest on trees and shrubs with small leaves. Particular plants include birch trees, butterfly bushes, and honey locusts. Don’t worry if you do not have these plants in your yard—your hummingbird might also rest on your feeder’s hanger.

Common Hummingbirds Types

Among the most common hummingbirds are the Ruby-throated, Rufous, and Anna’s Hummingbirds.

Ruby-throated Hummingbird
Only the Ruby-throated Hummingbird usually visits areas east of the Mississippi. The males have a distinctive ruby-red throat. Females are greenish, with a white throat and a notched tail.

The Ruby-throated Hummingbird has a range which closely follows deciduous forests east of the 100th Meridian, according to 1982 research by R. I. Bertin. While most Ruby-throated Hummingbirds cross the Gulf of Mexico, some take a more leisurely route along the coast during spring migration to Mexico and Central America and back in the fall. Males arrive about a week before females during both migrations. Learn more about the attracting the Ruby-throated Hummingbird.

Rufous Hummingbird
A popular hummingbird in the western United States, it makes the longest migration—to northern Alaska—for a bird so small. They have been extensively studied for foraging behavior and pollen transfer. An orange gorget and rufous flanks identify this species. Researchers believe that Rufous Hummingbirds had a major influence on the speciation of flowers in California.

Anna’s Hummingbird
A resident of the Pacific and Southwest states, the male is identified by it’s red throat and crown. The female has a small red patch on its throat.

What Do Hummingbirds Eat?

Hummingbirds live on flower nectar and insects, supplemented by food from hummingbird feeders.  

Hummingbird Feeder Recipe
The most common feeder recipe is a mixture of 1 part (cup) sugar to 4 parts (cups) water heated enough to dissolve the sugar and allow to cool before putting into feeders. Many hummingbirds pay little attention to commercial preparations of color-tinted water even though they have excellent color vision. Hummingbirds have remarkable spatial memories and flutter before feeders before they are even hung in the spring.

Are hummingbirds attracted to the color red?

The hummingbird is a prolific pollinator of flowers. Research shows that Ruby-throated Hummingbirds deposit 10 times as much pollen as bumblebees. So, to attract hummingbirds to your garden, make sure to include lots of plants known to attract hummingbirds.

What is a hummingbird’s favorite flower? Try bee balm and foxglove, just to name two. The Old Farmer’s Almanac and local nurseries will have a list of plants for hummingbirds.

When Do Hummingbirds Mate?

Hummingbirds generally mate between March and July, with mid-May being the height of the breeding season.

These tiny flyers are especially vocal during the breeding season, when males interact with other males. Sounds vary from chittering to a humming sound caused by wing movement.  

The female selects the nest site and builds the nest—the size of a thimble!—within a week. Common materials for nests are moss and lichen, plant down, spider silk, cotton fibers, feathers, and fur or hair rubbed off on leaves.

Two very small eggs hatch in about 14 days, and the young fledge in 3 weeks. Pairs are only together a few days or weeks. After mating, the male is on his own, leaving the female to incubate the eggs and feed the young mostly a diet of insects.

What’s a Hummingbird’s Life Span?

The life expectancy of a hummingbird is from 3 to 6 years. The oldest surviving hummingbird was 9 years old. Females outlive males by several years, probably due to the males’ high energy costs of defending territories and the long spring and fall migrations.

Hummingbird Predators

The main predators of hummingbirds are swift-flying raptors, such as kestrels; other birds, such as blue jays; and some insects, such as the Praying Mantis. Occasionally, one is caught by a large fish as the bird sips nectar from a pond lily.

Tom Warren has had an interest in birds since the age of 3, when he lived across from the President of the Massachusetts Audubon Society, who showed Tom how to care for injured birds. Later, a neighboring grandmother taught him the songs of warblers and thrushes, and in the eighth grade, his Middle School biology teacher took his class on birding excursions every weekend. Tom has guided bird walks and owl prowls for conservation groups, and has also participated in annual Christmas Bird Counts and the Hawk Watch on Pack Monadnock Mountain. Throughout the years, he has spent time at Pt. Pelee in Ontario observing the spring migration and has traveled to a variety of other migration areas. Tom is also committed to protecting birds and their habitat as a Trustee for both Massachusetts and New Hampshire Audubon, and the Harris Nature Center.

Have you ever seen a baby humming bird and when do they leave the nest? Are they adult size or smaller?

baby hummingbirds

I have seen tiny baby hummingbirds. They leave the nest between 18-22 days. Fledgling mass is much greater than normal adult mass (4.85 grams vs 3.3 grams for average adult female). Mass decreases sharply after fledging but tail length does not increase until end of summer.

Nest

What can I do to help, if possible, Humming birds build a nest? I have lots of trees that are mostly all natural ground. Thank you for your time and knowledge. Crystal

nest

Hummingbirds select the tip of a down sloping branch, open below and leaf canopy above. Popular trees are oak, hornbeam, yellow birch, poplar or pine.

Hummingbirds

What a wonderful article about these fascinating, miniature birds. They are beautiful, and truly amazing. Thank you.

Hummingbird Eggs;

The eggs take 2 weeks to hatch; 3 more weeks to fledge; five weeks total eggs to fledglings;:)

fledglings

You are correct. From eggs to fledging about 5 weeks. Then the whole family comes to flowers and feeders all summer.
