The ocean’s depths hold countless wonders, and among them are some of nature’s most extraordinary aviators. These are the birds that swim underwater to catch fish, defying conventional expectations of what a bird can do.
These ‘underwater hunting birds’ exhibit a fascinating array of adaptations. They thrive in aquatic environments, using various techniques to secure their prey. From powerful propulsion to specialized beaks, their diving abilities are truly remarkable.
Masters of the Deep: Penguins and Puffins
Penguins are iconic aquatic birds of the Southern Hemisphere. They are widely known for their exceptional swimming abilities.
These remarkable birds use their flipper-like wings for powerful underwater propulsion. They can reach speeds up to 22 mph while expertly chasing fish, squid, and krill.
Penguins possess streamlined bodies and dense bones. These adaptations significantly aid their agility and efficiency underwater. Some species, like the Little Penguin, can dive to 30 feet.
Emperor Penguins are truly astounding, reaching over 1,850 feet deep. They can stay submerged for around 20 minutes on average.
Puffins, often affectionately called ‘sea parrots,’ are another group of impressive divers. They utilize strong wings to propel themselves through the water.
All four species of puffins swim underwater to find food. They also nest underground and can carry multiple fish in their bills to feed their hungry chicks. These charming birds can dive to depths of up to 200 feet.
Stealthy Submergers: Cormorants and Loons
Cormorants are expert divers and formidable hunters. They use their webbed feet and dense bones to stay submerged and chase fish.
These birds can hold their breath for up to two minutes. They are capable of diving to depths exceeding 100 feet. Groups of cormorants sometimes even herd fish, making their hunting efforts more effective.
Their feathers are naturally less waterproof, which actually aids their diving. However, this means they often need to dry their wings in the sun afterward.
Loons are another group of expert underwater swimmers. They possess solid bones that help them sink and stay submerged with ease.
Their powerful webbed feet provide excellent propulsion. Their distinctive red eyes are specially adapted to spot prey underwater. Loons can swim up to 20 miles per hour and hold their breath for five minutes.
Diverse Diving Strategies: Ducks and Pelicans
Ducks, particularly diving ducks like eiders, long-tails, and mergansers, are adept at underwater foraging. They can dive deep and remain submerged for a minute or more.
They feed on a varied diet, including aquatic vegetation, small fish, and insects. King Eiders are among the deepest diving ducks, remarkably capable of reaching depths of 180 feet.
Pelicans are impressive divers known for their dramatic plunges. They dive from heights of up to 100 feet to stun fish.
Once submerged, they scoop up their prey in their large pouches. Despite their initial aerial dive, pelicans demonstrate a strong ability to swim underwater, holding their breath for 20 minutes and diving to 60 feet.
Unique Hunters: Gannets, Anhingas, and Kingfishers
Gannets are incredibly fast swimmers, capable of reaching speeds up to 60 miles per hour. They can quickly dive to nearly 100 feet, often hunting in large groups for efficiency.
They skillfully use both their wings and webbed feet for propulsion and superior maneuverability underwater. Anhingas, also known as ‘snakebirds,’ get their name from their long necks appearing above water while swimming.
These birds are skilled underwater hunters, propelling themselves with webbed feet. They uniquely spear fish with their sharp bills.
Anhingas lack waterproof feathers on their bodies, becoming saturated upon immersion. This helps them fully submerge, but also requires them to dry their wings in the sun afterward.
Kingfishers are known for their brilliant colors and incredible precision diving. They hover above the water, utilizing their excellent vision to spot prey.
They then dive at high speeds, up to 25 mph, to catch small fish, shrimp, or tadpoles with their sword-like beaks. Kingfishers typically dive near the surface, generally not going deeper than 10 inches.
Beyond the Usual: Dippers, Ospreys, and Diving Petrels
Dippers are truly unique among songbirds for their remarkable ability to walk underwater. They possess dense, waterproof plumage and strong legs.
These adaptations allow them to navigate fast-flowing streams. They hunt for aquatic insects, larvae, and small fish by walking along the stream bed.
Ospreys exclusively eat fish and have developed excellent diving skills. They can close a special semi-transparent eyelid underwater. This acts as natural goggles, helping them see their prey clearly.
Diving Petrels are seabirds with heavy bodies and short wings. These features are perfectly adapted for propelling themselves efficiently through the water. These impressive birds can dive over 200 feet deep.
