A drinking bird, also known as the dunking bird, drinky bird, water bird, and dipping bird, [1] [2] [3] is a toy heat engine that mimics the motions of a bird drinking from a water source. They are sometimes incorrectly considered examples of a perpetual motion device.
A grey heron in delta-wing posture, facing the Sun. Sunning or basking, sometimes also known as sunbathing, is a thermoregulatory or comfort behaviour used by humans, animals, especially birds, reptiles, and insects, to help raise their body temperature, reduce the energy needed for temperature maintenance or to provide comfort.
Birds also bathe in water or dust themselves. While some birds dip into shallow water, more aerial species may make aerial dips into water and arboreal species often make use of dew or rain that collect on leaves. Birds of arid regions make use of loose soil to dust-bathe.
A recent video uploaded by the U.S. Fish and Wildlife Service shows a group of spinning Wilson's Phalaropes in Quivira National Wildlife Refuge, Kansas. The USFWS post notes, "there is a lot of ...
Manx shearwaters engage in a behaviour termed "rafting", where birds sit, often in large groups of more than 10,000, on the water adjacent to their Skomer Island breeding colony before and after visiting their chicks. Rafts move closer to the island during the night and further away in the morning which produces a "halo" effect - where no birds ...
Because birds fly at an angle relative to the wind during dynamic soaring, they must be able to achieve flight speeds greater than this head wind. Consequently, birds that rely on dynamic soaring tend to have low wing loadings and high aspect ratios. In other words, gliding birds have wing shapes that allow them to behave more like fixed wing ...
The hilarious video was shared by the TikTok account for @Kiki.tiel and people can't get enough of this musical bird. One person commented, "You didn’t turn it off, just snoozed it."
Dipping is common when birds are sitting on the water, and gulls may swim in tight circles or foot paddle to bring marine invertebrates up to the surface. Food is also obtained by searching the ground, often on the shore among sand, mud or rocks. Larger gulls tend to do more feeding in this way.
