The neck of plunge-diving birds is also unique. Plunge-diving birds can dive from heights up to 45 m and reaching speed up to 24 m/s without injury. Their neck plays a big role when plunge-diving. Their neck muscle will contract during the impact process, and the tendons will apply tension to the bones as a stabilizing force during the dive. [7]
The back of the head and the neck have elongated feathers that have been described as gray [16] or light purple-white. [14] The upper back of the body and wings are spotted or streaked with white. [16] The female anhinga is similar to the male except for its pale gray-buff [17] or light brown [18] head, neck, and upper chest. The lower chest or ...
Grebes (/ ˈ ɡ r iː b z /) are aquatic diving birds in the order Podicipediformes (/ ˌ p ɒ d ɪ s ɪ ˈ p ɛ d ɪ f ɔːr m iː z /). [1] Grebes are widely distributed freshwater birds, with some species also found in marine habitats during migration and winter. Most grebes fly, although some flightless species exist, most notably in stable ...
The bones of diving birds are often less hollow than those of non-diving species. Penguins , loons , [ 2 ] and puffins are without pneumatized bones entirely. [ 3 ] [ 4 ] Flightless birds , such as ostriches and emus , have pneumatized femurs [ 5 ] and, in the case of the emu, pneumatized cervical vertebrae .
Grebes are small to medium-large freshwater diving birds. They have lobed toes and are excellent swimmers and divers. However, they have their feet placed far back on the body, making them quite ungainly on land. Pied-billed grebe, Podilymbus podiceps; Horned grebe, Podiceps auritus; Red-necked grebe, Podiceps grisegena; Eared grebe, Podiceps ...
The ring-necked duck (Aythya collaris) is a diving duck from North America commonly found in freshwater ponds and lakes. [3] The scientific name is derived from Greek aithuia , an unidentified seabird mentioned by authors including Hesychius and Aristotle , and Latin collaris , "of the neck" from collum , "neck".
The dinosaur, called Natovenator polydontus, lived about 72 million years ago during the Cretaceous Period and was built like a diving bird with a streamlined body while possessing a goose-like ...
Herons and egrets are wading birds with long necks and legs. Herons are large and egrets are smaller. Bitterns tend to be shorter-necked and more secretive. Unlike other long-necked birds such as storks, ibises, and spoonbills, members of the Ardeidae fly with their necks pulled back into a curve. American bittern, Botaurus lentiginosus
