  2. Anhinga - Wikipedia

    en.wikipedia.org/wiki/Anhinga

    The word anhinga comes from a'ñinga in the Brazilian Tupi language and means "devil bird" or "snake bird". [3] The origin of the name is apparent when swimming: only the neck appears above water, so the bird looks like a snake ready to strike. They do not have external nares (nostrils) and breathe solely through their epiglottis.

  3. Jacanidae - Wikipedia

    en.wikipedia.org/wiki/Jacanidae

    Young chicks may also be held under the wing and transported to safety by the parent bird in some species. [21] Young chicks dive underwater and stay submerged with only their bill out of water. Some adult jacanas also use the same technique. African jacanas go through a simultaneous moult of their flight feathers leading to a period of ...

  4. Diving bird - Wikipedia

    en.wikipedia.org/wiki/Diving_bird

    Such birds may enter the water from flight, such as pelicans, gannets and tropicbirds; or they may dive from the surface of the water, such as the diving ducks, cormorants and penguins. It is theorized that they evolved from birds already adapted for swimming that were equipped with such adaptations as lobed or webbed feet for propulsion. [1]

  5. Common murre - Wikipedia

    en.wikipedia.org/wiki/Common_murre

    The common murre is a pursuit-diver that forages for food by swimming underwater using its wings for propulsion. Dives usually last less than one minute, but the bird swims underwater for distances of over 30 m (100 ft) on a regular basis.

  6. Auk - Wikipedia

    en.wikipedia.org/wiki/Auk

    The speed at which small fish (which along with krill are the auk's principal prey) can swim doubles as the temperature increases from 5 to 15 °C (41 to 59 °F), with no corresponding increase in speed for the bird.

  7. Grebe - Wikipedia

    en.wikipedia.org/wiki/Grebe

    Most grebes fly, although some flightless species exist, most notably in stable lakes. The order contains a single family , the Podicipedidae , which includes 22 species in six extant genera . Although, superficially, they resemble other diving birds such as loons and coots , they are most closely related to flamingos , as supported by ...

  8. Dipper - Wikipedia

    en.wikipedia.org/wiki/Dipper

    The high haemoglobin concentration in their blood gives them a capacity to store oxygen greater than that of other birds, allowing them to remain underwater for 30 seconds or more, [9] whilst their basal metabolic rate is approximately one-third slower than typical terrestrial passerines of similar mass. [14]

  9. Bufflehead - Wikipedia

    en.wikipedia.org/wiki/Bufflehead

    These diving birds forage underwater. They prefer water depths of 1.2–4.5 m (3.9–14.8 ft). [8] In freshwater habitats, they eat primarily insects, and in saltwater, they feed predominantly on crustaceans and mollusks. Aquatic plants and fish eggs can often become locally important food items, as well.
