Hummingbirds: Good Things in Small Packages

Imagine you see a patch of beautiful tube-like flowers as bright as the sunset. You lean close, wondering whether they'll smell of honeysuckle or roses.

A chirp surprises you, and you look up to see a flash of purple and green no bigger than your thumb hovering over the flowers. It blurs past you and up into the trees.

Is that thing that buzzed by your head an insect? No. It's a hummingbird.

If you spend some time watching hummingbirds you will see they have a big attitude, and yet these little daredevils are the smallest birds in the world. Many species wear flashy colors that make other birds look dull. With their amazing flying abilities, color, and the size, hummingbirds are one of the most famous groups of birds in the Americas.

The Geography of Hummingbirds

People who live in Europe, Asia, Africa or Australia can put out a hummingbird feeder every day, but they will never attract a single hummingbird to their gardens.

This rufous hummingbird is the only species that breeds as far north as Alaska. Click for more detail.

All hummingbirds are native to North, Central or South America. Not a single species of hummingbird lives outside of the Americas.

Scientists know of about 338 species of hummingbirds, and more are likely to be discovered. However, if you live in North America, you may have only seen one or two species of hummingbirds in your life.

Most hummingbirds live in Central or South America because hummingbirds are most common near the equator where there are flowers year-round.

Only sixteen species live in North America, and only a few hardy species live as far north as Alaska.

Hummingbird Diversity

All hummingbirds are small, nectar-eating birds. They have large heads (relative to body size) and flexible wings. Their feet are so tiny that these birds, along with a group of insect-eating aerial acrobats called the swifts, are called the Apodiformes, which means "no feet."

However, once you look past these similarities, hummingbirds are very diverse. Their beaks come in different lengths and shapes, depending on the sort of flower they most like to visit. The smallest weighs less than a United States penny. The largest would weigh little more than a pile of ten pennies. 

Hummingbirds also come in many colors and patterns. But not every species of hummingbird is colorful, and even among the most colorful species, females are usually plain green or brown.
