Pelicans at least.
In penguins, it actually helps them during their dive to conserve air. However, I am not sure how it is cured in pet birds.
Birds that dive or swim in water, such as ducks and penguins, have waterproof feathers due to a special oil produced by a gland near their tails. This oil coats the feathers, preventing water from soaking in and keeping the birds dry and buoyant. Additionally, their feathers are structured to trap air, providing insulation and aiding in buoyancy when submerged. This combination allows them to effectively hunt for food in aquatic environments without becoming waterlogged.
Kingfishers like all birds do not have teeth.
Submarines dive by opening vent valves that allow sea water to push air out of their ballast tanks.
Penguins are birds and like all birds they get oxygen by breathing air.
Crocodiles don't generally dive, the slide into the water from a bank and swim close to the surface to break for air.
No..They are birds, and birds don't live in water._____________________________Eagles are large birds; they primarily live in the air. Eagles nest in tall trees, on the edges of cliffs or on tall buildings.Eagles are excellent fishers; they can see fish swimming in the lakes and rivers below them, swoop down and capture the fish in their talons. Occasionally, they misjudge the distance and hit the water. In this case, if uninjured, the eagle is capable of taking off from the water.
The increase in water pressure as you dive deeper compresses the air inside the balloon, causing it to shrink in size. The higher pressure squishes the air molecules closer together, reducing the volume the balloon occupies.
Along with standing and walking, they can be used to dive and swim. When landing on water they are used as skis when slowing down (geese and mallards landing (sic) are quite spectacular); on take off they can be used to run on the water to get air speed.
Dolphins are mammals. They breathe air with lungs, pretty much just like you and I. They can't breathe water. When they dive they hold their breath.
their is no air in the water
Birds have evolved a streamlined shape to reduce air resistance and enhance their diving efficiency when catching fish. This aerodynamic design allows them to plunge into the water with minimal drag, enabling faster and more controlled dives. Additionally, a streamlined body helps them quickly transition from air to water, improving their chances of successfully catching prey while minimizing energy expenditure. Overall, this adaptation is crucial for their hunting strategy and survival.
