Hummingbird Tongues: The Surprising Science Behind Their Incredible Feeding Abilities

The tongues of hummingbirds are designed to get nectar from flowers. When they lick nectar, the grooves on the top and bottom of their tongues make a tube shape.

When a bird moves its tongue, it makes a vacuum that pulls nectar into its mouth. Also, the tip of a hummingbird's tongue has tiny hairs that catch nectar and move it to the back of the mouth so the bird can swallow it. Hummingbirds can get energy from nectar because of how they are built and act.

Hummingbirds have long tongues inside their beaks, which lets them eat up to three times their body weight in nectar and bugs daily. As Sid Perkins writes in Science, scientists have discovered something they didn't know about those tiny tongues: they work like pumps that pull nectar into the mouth.

Perkins says the discovery changes the long-held idea that hummingbird tongues are more like straws. The old idea was supported by the fact that birds seem to get nectar by using capillary action, which pulls liquid into tight spaces against gravity.

The hummingbird's tongue is split in two, and the ends of its tongue, which look like hair, are called lamellae. When the tongue is inside the flower, it breaks, and the lamellae grow outward. When the bird pulls its tongue in, the tips touch, and the lamellae roll inward. By doing this, the nectar gets stuck in the tongue.

How Do Hummingbirds Use Their Tongues?

They use them to get nectar, which is a liquid. The flower makes this sugary water nectar to attract the bird, so the bird sticks its head into the flower and eats. But since the bird stuck its head into the nectar-making parts of the flower, the plant gets these pollination services in return.

The flowers touch the bird's face with pollen-bearing parts in many ways. When a bird's beak gets stuck in flower, it moves pollen from one flower to the next. Because of this, it's like a deal. The situation has helped everyone in some way.

How Fast Does A Hummingbird Tongue Move?

The tongue of a hummingbird moves quickly, between 13 and 15 licks per second. This speed helps the hummingbird get nectar from flowers quickly and easily. The bird can move quickly because it has a fast metabolism, and its tongue has special muscle fibers that help it move quickly.

Do Hummingbirds Eat At Night?

Hummingbirds are most active during the day and often eat to keep up with their fast metabolism. But some species of hummingbirds can eat at dawn or dusk if they have to, especially when they are on the move or when food is scarce. Most of the time, hummingbirds roost at night to save energy and sleep instead of feeding.

People have seen hummingbirds feed at night, but this happens most often in the summer. You might see a hummingbird or two if you leave your outdoor lights on.

The protein these little birds need comes from the insects they eat. The night is when hummers hunt for food, so if you see them flying around at night, keep an eye on them. The only time they don't eat is at night. At night, the heart rate and the body temperature of hummingbirds drop to about 50 bpm. Because of this, their breathing slows down a lot.

How Often Do Hummingbirds Eat?

Hummingbirds often eat to keep up with their high metabolism. During the day, they often eat every 10 to 15 minutes. They eat only a tiny amount of nectar at each meal, but this sugary solution gives them most of their energy and nutrients. Hummingbirds can also get protein from minor bugs and spiders. During migration or when food is scarce, they may eat less often, but they will still try to find food as often as possible to fuel their active lives.

Every day, from dawn until dusk, hummingbirds feed on nectar. As the sun goes down, they look for a place to spend the night. During the day, they have to eat often—anywhere from 3 to 7 times—but at night and when it's cold, they can slow down their metabolism and use less energy.

When The Sun Goes Down, What Are Hummingbirds Up To In The Dark?

When the sun goes down, hummingbirds enter a state called "torpor," similar to hibernation. During this time, they save energy by lowering their body temperature, slowing their metabolism, and becoming less active. Hummingbirds will sit on a branch or in a safe place and tuck their heads under their feathers to stay warm. They will stay in this sleepy state until dawn, when they wake up and start eating again. Hummingbirds can save energy by going into torpor every night. This helps them get through times when there isn't enough food or terrible weather.

Because their feathers don't keep them very warm, hummingbirds sleep with fluffed wings.

For these birds, body heat is the only way to stay warm. Since nectar eaters have a fast metabolism, they need to eat often to keep up their energy.

Hummingbirds will often hover over feeders and flap their wings quickly. When hummingbirds go to sleep at night, they do something like half-sleep. Torpor is the name for this kind of sleep disorder.

To do this, the hummingbird's metabolism will be slowed while it is hibernating. The hummingbird's body temperature and heart rate will drop fifty beats per minute.

About 60% of the energy the hummingbird would normally use is saved. When they are laying eggs, female hummingbirds rest in their nests. The birds use horizontal tree branches to make these nests.

What Do Hummingbirds Do When It Rains?

When it rains, hummingbirds may seek shelter from the rain to protect their feathers and keep warm. This can be under the leaves of trees or bushes or in a sheltered area such as a birdhouse or covered patio.

During heavy rains, hummingbirds may be less active and feed less frequently, conserving energy and waiting for the rain to stop. When the rain ends, and the nectar in flowers becomes available again, the hummingbirds will resume their normal feeding activities.

It's also worth noting that some hummingbirds can withstand light to moderate rain and may continue to feed as long as the nectar in the flowers is still accessible.

Even when it's raining lightly, or there are light showers, hummingbirds do their regular business. In the summer, they often look forward to light rain because it gives them a break from the heat and lets them fly and eat with less energy.

When it rains harder, they may move to places with more cover and eat from feeders or other food sources. If it doesn't rain too hard, they can still take off.
