What Does a Male and Female Ruby Throated Hummingbird Look Like?
The male ruby throated hummingbird steals the show with a green body and ruby red throat that glistens like jewels in the sunlight. Its vibrant green head glows, too! The female isn’t as grandiose in appearance. It sports a green head with white underparts and black masks near the eyes. Both sexes have a metallic green back. They measure about 3 3/4 inches long with a wingspan of 4 1/2 inches.

Ruby Throated Hummingbird Nest
From midspring through late summer, the female ruby-throat is constantly on the move. She chooses a nest site, builds a nest, incubates eggs and raises the baby hummingbirds all on her own. The males don’t play a role. She’s doing all this while trying to keep herself fueled and fed!
These tiny fliers build a cup-shaped nest with moss, spiderwebs and camouflaged with lichen. The female lays two tiny white eggs that look like jelly beans.

Juvenile Ruby Throated Hummingbird
All juvenile ruby throated hummingbirds look so similar to females that it’s often nearly impossible to tell the difference. About 15 days after hatching, baby hummingbirds stand up on the edge of the nest and exercise their wings. They leave the nest a few days later. Young fledglings can’t feed themselves; it takes practice to hover and drink nectar. The female continues to feed them for up to a week as they learn how to find food.
Whether a male, female or juvenile ruby throated hummingbird chooses your yard, their acrobatic, territorial and erratic antics always entertain.

What Do Ruby Throated Hummingbirds Eat?

Their diet consists of nectar, small insects and tree sap. Invite these teeny delights into your yard with offer sugar water and tube-shaped flowers in their three favorite colors: red, orange and pink.

Habitat and Range Map
Several hummingbird species are sprinkled over the western half of North America, including Anna’s and Allen’s hummingbirds. But only one, the ruby throat, flies the eastern skies regularly. Look for them in gardens, woodland edges and parks.
Among the most common and successful hummingbirds, ruby throats are found in summer across most of the eastern U.S. and east of the Rockies in southern Canada. Their population totals an estimated 34 million birds. Do hummingbird sightings have special meaning?

Ruby Throated Hummingbird Migration
Ruby throated hummingbirds move south in late summer and early fall. Ruby throats may fly more than 3,000 miles from Canada to Costa Rica. And some fly nonstop 500 miles across the Gulf of Mexico during migration. That’s quite a feat for a bird that weighs a little less than 4 grams.
They need food sources to fuel their migration journey. A good rule of thumb is to leave your feeders up for a couple of weeks after you see the last one pass by.

Wing Speed and Heart Rate
These little creatures fly about 25 miles per hour and zoom even faster when the wind pushes them along. Zipping around in every direction (even backward), the nimble ruby throated hummingbird beats its wings around 53 times per second.
When ruby throats are really exerting themselves, their hearts race around 1,200 beats per minute. In calmer times, that rate drops to 600 beats per minute. Humans, in comparison, have a resting heart rate of about 72.
