When we imagine
birds, we usually think of them gliding through the sky or perched gracefully
on trees. But some birds are far more versatile than that. A fascinating group
of birds has developed the extraordinary ability to dive and swim underwater to
catch fish. These unique hunters combine aerial skills with aquatic agility,
making them some of the most specialized animals on Earth.
How Birds Swim
Underwater
Birds that dive
underwater use either their wings or their feet as paddles. Unlike birds that
only skim across the surface, diving birds have streamlined bodies designed to
cut through water smoothly. Their movements underwater often resemble flying,
as they flap their wings or kick with their strong legs to chase prey.
Special
Adaptations for Underwater Hunting
- Dense
Bones – Unlike most birds that have
hollow bones to stay light for flying, diving birds have denser bones.
This extra weight helps them sink quickly and avoid floating back up.
- Waterproof
Feathers – Their
feathers are coated with natural oils that repel water, keeping their
bodies insulated and dry.
- Keen
Eyesight – These
birds can adjust their vision from air to water, allowing them to spot
fish clearly even in dim or murky conditions.
- Sharp
Beaks – Designed to snatch slippery
fish, their beaks are strong, pointed, and often hooked at the tip.

Here are some
of the most fascinating examples of diving birds:
1.
Penguins
Penguins are the masters of underwater swimming. Unlike most birds, they cannot
fly in the air, but they “fly” gracefully underwater. Using their wings like
flippers, penguins can swim at speeds of up to 15 miles per hour. Their diet
mainly consists of fish, krill, and squid, making them some of the ocean’s most
efficient hunters.
2.
Cormorants
These long-necked birds are excellent divers, often plunging deep into rivers,
lakes, and seas to hunt fish. They use their webbed feet to propel themselves
underwater. After hunting, they are often seen perched with wings spread wide
to dry, as their feathers are less waterproof than other diving birds.
3.
Puffins
Often called “sea parrots” because of their colorful beaks, puffins are expert
swimmers. They occasionally descend more than 60 meters to chase fish by
flapping their wings underwater. Because of their unique tongues, puffins are
also adept at holding several fish in their beaks at once.
4.
Grebes
Grebes are freshwater divers known for their elegant movements. They can stay
underwater for up to 30 seconds, catching fish, crustaceans, and insects.
Unlike penguins or puffins, grebes primarily use their powerful legs to swim
underwater.
5.
Murres
and Guillemots
These seabirds dive using their wings, much like penguins. They can reach
impressive depths, chasing small fish and other marine creatures. Colonies of
murres and guillemots are often found on rocky cliffs, where they nest in large
numbers.
Why Underwater
Hunting Matters
The ability to
dive and swim underwater gives these birds a significant advantage. They can
access prey that hides beneath the surface, where many predators cannot reach.
This reduces competition for food, allowing them to thrive in environments
where surface feeders would struggle.
Additionally,
these birds play a key role in balancing aquatic ecosystems. By feeding on fish
and small marine creatures, they help regulate populations and maintain healthy
waters.
Conclusion
Birds that swim
underwater to catch fish are living examples of nature’s endless creativity.
From penguins darting through icy waters to puffins carrying beakfuls of fish
across the sea, each species is uniquely adapted to its environment. These
incredible hunters blur the line between air and water, reminding us of the
diversity and adaptability of wildlife.
Watching them
in action feels like witnessing a bird transform into a fish—an awe-inspiring
display of survival skills shaped by evolution.
FAQs About Birds That Swim
Underwater to Catch Fish
1. What bird is the best swimmer
underwater?
Penguins are considered the best underwater swimmers among birds. They can dive
to great depths and swim at high speeds using their wings as flippers.
2. Can all birds swim underwater?
No, only certain species have evolved to dive and hunt underwater. Examples
include penguins, cormorants, puffins, grebes, murres, and guillemots.
3. How do diving birds breathe while
underwater?
Diving birds hold their breath while submerged, just like marine mammals.
Depending on the species, they can stay underwater anywhere from 20 seconds to
several minutes.
4. Do these birds only eat fish?
Most diving birds primarily eat fish, but their diets can also include
crustaceans, squid, and aquatic insects, depending on their habitat.
5. Why do cormorants spread their
wings after swimming?
Unlike many diving birds, cormorants have feathers that are not fully
waterproof. After diving, they spread their wings to dry in the sun.
