Hummingbirds: Photos, Species, Behavior, Migration & Conservation
Hummingbirds are some of the tiniest, most fascinating birds in the Americas. People love their bright feathers and the way they can hover in place while eating. They’re special because they can fly in every direction – even backward – and their wings move so fast you hear a hum. There are about 375 known species, living from Alaska all the way down to Argentina, but most stick to Central and South America.
With their slender beaks and zippy moves, hummingbirds drink nectar from flowers and grab tiny insects right out of the air. They’ve got a super high metabolism and crazy agility, which lets them live in all sorts of places. Some even travel thousands of miles during migration – pretty wild for such a little bird.

Hummingbird Family and Classification
Hummingbirds belong to a group of tiny, fast birds that come in many shapes and colors. They stand out for their rapid wing beats, bright feathers, and their place in bird evolution.
The Trochilidae Family
Every hummingbird is part of the Trochilidae family. This group includes more than 350 species and over 100 genera. Trochilidae birds are native to the Americas, found nowhere else. Nearly half of all hummingbird species live near the equator, especially in Central and South America.
Most members are small – usually between 7.5 and 13 cm (3–5 inches) long. The bee hummingbird is the tiniest at about 5 cm, while the giant hummingbird can reach 23 cm. They all have shiny feathers, slender bills, and can hover or fly backwards. Their sparkling colors and flight tricks really make them different from other birds.
Relation to Other Birds
Hummingbirds are in the order Apodiformes, along with swifts and treeswifts. Their closest living relatives are swifts, and they share some bone and wing features. But unlike swifts, hummingbirds eat mostly nectar and small insects, thanks to their long, thin beaks and special tongues.
They might look like sunbirds and honeyeaters, but that’s just because of similar lifestyles, not because they’re related. Sunbirds and honeyeaters live in the Old World, while hummingbirds are only in the Americas. Studies on bird classification make this clear.
Evolution and Diversity
Hummingbirds split from their ancestors, the swifts, about 42 million years ago. The oldest fossil found, Eurotrochilus, is about 30 million years old. Scientists think hummingbirds started out in South America, where most of them still live today.
There are about 366 recognized hummingbird species now. They’re grouped into nine big branches, like the bees, coquettes, mangoes, and emeralds. The Trochilidae family is one of the biggest bird families, and each species has its own special traits for surviving in its home.
Physical Characteristics and Adaptations
Hummingbirds are tiny birds with bodies made for hovering and zipping around. They’re small, bright, and can even slow down their bodies when they need to.
Size and Weight Range
Hummingbirds are some of the world’s smallest birds. The bee hummingbird from Cuba is the tiniest, just over 5.5 cm (about 2.2 inches) long and under 2 grams.
The giant hummingbird, the biggest, grows to about 20 cm (8 inches) and weighs about 20 grams. Most are in between, usually 7 to 9 cm long and about 3 to 4 grams in weight.
Being so light helps them move quickly and use less energy while flying. Size and weight can change a bit depending on the species and where they live, but all hummingbirds are built for speed and feeding. For more details, here’s a page with facts and figures about hummingbird size.
Iridescent Feathers and Coloration
Hummingbird feathers are famous for their shiny, iridescent colors. Tiny plates on their feathers reflect light and make them shimmer in greens, reds, blues, and golds. The color you see depends on the sunlight angle.
These bright colors help attract mates and tell species apart. Males are usually more colorful than females, which helps them stand out during courtship. Most of the color isn’t from pigment, but from how their feathers reflect and scatter light.
People often spot different species by their throats, or gorgets, which can glow red, orange, or purple in the sun. This shimmering effect is hard to forget when you see a hummingbird feeding. For a deeper dive into their iridescent feathers and unique coloration, check out this guide.
Flight Abilities and Unique Anatomy
Hummingbirds can hover, fly backwards, and even move sideways. Their wings rotate almost 180 degrees at the shoulder, and they beat their wings up to 70 times per second. This lets them stay in place while drinking nectar.
Their flight muscles, especially the pectoral muscle, are super strong, making up about a third of their body weight. Hollow bones keep them light but tough.
They have long, needle-like beaks and tongues made for reaching deep into flowers. Their feet are tiny and not really for walking – just perching. Hummingbirds have big eyes and brains for their size, which helps with quick moves and aiming for flowers. You can read more about their flight adaptations and anatomy if you’re interested.
Metabolism and Torpor
Hummingbirds have one of the fastest metabolisms of any animal. Their wings and constant movement burn a ton of energy, so they eat a lot – mostly nectar, but also small insects for protein. Their heart can beat over 1,200 times a minute when they’re active.
At night or when food’s scarce, hummingbirds go into a state called torpor. It’s kind of like deep sleep: their body temperature drops, and everything slows down so they save energy. This is key for survival, especially when food is hard to find. If you want to learn more, here’s a good link about torpor and hummingbird metabolism.
Hummingbird Species Around the World
Hummingbirds come in hundreds of types, mostly in the Americas. Many have evolved for certain habitats, and some only live in one country or even one small area.
Notable Hummingbird Species
The bee hummingbird from Cuba is the world’s smallest bird – about 2 inches long and less than 2 grams. On the other end, the giant hummingbird from the Andes is the biggest, at around 8–9 inches. That’s a huge size range for one family of birds.
In North America, you’ll find the ruby-throated hummingbird in the eastern U.S. and the anna’s hummingbird out west all year. The rufous hummingbird is famous for its long migrations, and the black-chinned hummingbird adapts to lots of places. In California, the allen’s hummingbird and the bright costa’s hummingbird stand out. The violet-crowned hummingbird lives in southwestern deserts and Mexico.
If you want something really different, check out the sword-billed hummingbird from South America – its bill is longer than its body! This helps it reach deep flowers. More amazing species are featured at Hummingbird Central.
Distribution and Habitats
You’ll only find hummingbirds in the Americas, with the most species in Central and South America. Colombia, Ecuador, and Peru have the most, and Colombia alone has over 160 types.
In North America, fewer than two dozen species visit the U.S. and Canada regularly. Mexico has around 59 species. Central American countries like Costa Rica and Panama each have over 50, and South America’s rainforests and mountains have the biggest variety.
Most hummingbirds live in tropical forests, cloud forests, or mountains. Some, like the ruby-throated hummingbird, migrate thousands of miles, while others stay in one area year-round. Even Caribbean islands have unique hummingbird species adapted to their local spots.
Endemic and Rare Species
Lots of hummingbirds are endemic, meaning they only live in one country or even one small island. The bee hummingbird is found only in Cuba. The giant hummingbird sticks to the Andes from Ecuador to Chile. Other island birds include the Jamaican streamertail and the Puerto Rican emerald.
South America has tons of rare and limited-range species, often in tiny patches of forest or high up in the mountains. Sadly, habitat loss and changes in the environment put many of these birds at risk, and some are super hard to find now.
Some hummingbirds are so rare, or live in such out-of-the-way places, that you’d have to travel far just to spot one. Scientists and bird lovers are working to protect these birds and their homes, since many could disappear for good.

Diet and Feeding Behavior
Hummingbirds rely on both nectar and insects for food. Their eating habits give them enough energy to fly and enough protein to stay healthy and grow.
Nectar Feeding
Nectar gives hummingbirds most of their energy. They use their long bills and tongues to reach deep inside flowers for the sweet liquid. Nectar is packed with simple sugars like glucose and fructose, so it works as quick fuel.
Most hummingbirds love red or orange tubular flowers, like bee balm, cardinal flower, and phlox. These have lots of nectar, which matches the birds’ speedy metabolism. Hummingbirds can visit dozens or even hundreds of flowers in a day.
Nectar isn’t enough for all their needs. Hummingbirds also drink sugar water from feeders, especially if wildflowers are scarce. Feeders need the right sugar-to-water ratio and should stay clean so the birds don’t get sick. Here’s more on feeding hummingbirds the right way.
Role of Insects in Diet
Insects and spiders are really important for hummingbirds, especially when they’re breeding or feeding chicks. Nectar doesn’t have enough amino acids, vitamins, or minerals, so hummingbirds hunt small bugs for these extras.
They catch insects while hovering, picking them off leaves, or even grabbing them in midair. Spiders matter a lot too – they’re full of protein, and sometimes their webs have trapped bugs, so that’s an easy snack.
Some hummingbird species eat more insects than nectar at certain times, depending on what’s around. Females eat even more insects when feeding chicks who need protein to grow. Check out the importance of insects in their diet.
Pollination and Ecological Importance
When hummingbirds look for nectar, they move pollen from flower to flower. Their bodies brush against pollen-covered flower parts, and this helps plants make seeds and fruit.
Some plants have colors and shapes that fit hummingbirds’ feeding style – like long, curved tubes. By visiting so many flowers, hummingbirds help keep plant life healthy and varied.
How they eat affects plant diversity and the animals that depend on those plants. There’s more about this in the guide to hummingbird foraging behavior.
Migration and Life Cycle
Hummingbirds travel far every year and have special nesting habits. Their life cycle goes quickly, from tiny eggs to flying on their own.
Migration Patterns
Hummingbirds migrate between places where they breed and where they spend the winter. Some species fly thousands of miles. The Ruby-throated Hummingbird, for example, crosses the Gulf of Mexico without stopping. When and where they migrate depends on the species and where they live. Most North American hummingbirds fly south to Central America or Mexico when it gets cold and food runs out.
They use set travel routes, called “flyways.” Changes in daylight, food, and temperature tell them when to go. On the way, they stop to rest and feed at flowers and feeders. Here’s a guide about hummingbird migration if you want more details.
Breeding and Nesting
Hummingbirds breed in spring and summer. Females pick the nest spot, usually on a tree branch, and build small nests out of plant fibers, lichens, and spider silk. These nests are tiny – about the size of a ping-pong ball or bottle cap – and blend in with their surroundings.
The female lays two small white eggs in each clutch. She’s the only one who sits on the eggs. Males don’t help with nest building, incubating, or raising chicks. Chicks hatch after about 11 to 17 days, depending on the species. You can see more about nests and eggs in these hummingbird life cycle facts.
Lifecycle and Lifespan
Hummingbird chicks hatch blind and featherless, weighing less than a gram. The mother feeds them mostly insects for protein. In about three weeks, chicks grow feathers and get strong enough to fly and leave the nest.
Most hummingbirds don’t make it through their first year because of predators, bad weather, or not enough food. If they do survive, they can live longer. Some banded hummingbirds have reached seven or eight years in the wild. The life cycle moves fast and depends a lot on the environment. For more on their development and how long they live, check this life cycle overview.
Human Interaction and Conservation Efforts
People affect hummingbirds in lots of ways. While watching them is fun, some things we do shrink their habitats or expose them to harmful stuff.
Hummingbird Feeders and Observation
Lots of folks set up hummingbird feeders to bring these birds close. Feeders give easy nectar, especially if flowers are hard to find. But they need to be cleaned and refilled often, or mold and spoiled sugar water can hurt the birds.
Where you hang feeders matters too. If they’re near windows, birds might crash and get hurt. Putting up window decals or hanging feeders away from glass helps. Watching hummingbirds through citizen science programs lets people help scientists track migration and local populations. These programs gather data that helps with conservation.
When people watch hummingbirds responsibly, it helps both the birds and us. More awareness means more people care and take steps to help hummingbirds survive.
Threats: Habitat Loss and Climate Change
The biggest threat to hummingbirds is losing habitat because of how people use land. Cutting down forests for farms and cities destroys places where hummingbirds nest and feed. When habitats break up, it’s harder for them to find food and safe spots.
Climate change makes things worse. Weather changes can mess up when flowers bloom, so food isn’t there when birds need it. Some hummingbird species face high risks because of these changes. More than 250 species are dropping in numbers, and some, like the Chilean Woodstar, are vanishing fast.
Pesticides and window crashes are also big problems. Fixing these issues is key for hummingbirds’ future. Here’s an overview of major dangers to hummingbirds.
Conservation Initiatives
People help hummingbirds in different ways. Planting native flowers is an easy way to support them. Gardens with local plants give hummingbirds food and places to nest. Some areas have protected land to keep key habitats safe.
Conservation groups teach the public, do research, and restore damaged places. Policies that limit building or encourage eco-friendly farming also help protect hummingbirds’ homes.
Citizen science and public action matter a lot. Programs that get people to watch local hummingbirds help track changes and spot problems, as the International Hummingbird Society points out. Every little bit helps give hummingbirds a better shot at survival.
Frequently Asked Questions
Hummingbirds are tiny birds with fast wings, special ways of eating, and long migration trips. You’ll mostly find them in the Americas, and lots of people attract them with certain plants and feeders.
How do you attract hummingbirds to your garden?
Plant red or orange tubular flowers like bee balm, salvia, or trumpet vine to draw in hummingbirds. Native plants work best – they give familiar nectar and shelter.
Putting out a sugar water feeder helps too. Place feeders in open spots, away from predators, and near flowers for best results. More tips are at Birds & Blooms.
What should you not put in a hummingbird feeder?
Don’t use honey, brown sugar, fake sweeteners, or red food dye in feeders. Only plain white sugar is safe. Other stuff can be bad or even deadly for hummingbirds.
Stick with four parts water to one part white sugar. Skipping other ingredients keeps birds healthy, according to hummingbird experts.
How can you prevent other birds from accessing hummingbird feeders?
Hang feeders where bigger birds can’t reach, like under eaves or from thin wires. Pick feeders with small perches – hummingbirds can hover and don’t need to land.
If needed, use feeders with tiny holes just for hummingbirds. Spreading out more than one feeder can also cut down on competition.
Can you explain the migration patterns of hummingbirds?
Many hummingbirds travel far between where they breed and where they spend winter. Ruby-throated hummingbirds, for example, can fly across the Gulf of Mexico in one go – about 500 miles.
On migration, they eat a lot to build energy, sometimes stopping in gardens and at feeders. In North America, they usually head south in fall and come back in spring. More info is at Hummingbird Central.
What is the typical habitat for hummingbirds?
Hummingbirds live in lots of places – gardens, forests, meadows, and anywhere with plenty of flowers. They like spots with lots of nectar and safe places to nest.
Shelter and water matter too. Some species do well in suburbs or even cities, as long as they’ve got food and shelter.
What are the distinctive sounds that hummingbirds make?
Hummingbirds make quick chirps and chatters. Most don’t really sing, but you’ll hear a humming or buzzing sound from their wings.
When they’re showing off or trying to defend their space, some will squeak or whistle in a really high pitch. The wing sounds change, too, depending on how fast they zip around or when they dive.
