Lesser flamingos flying in formation. When in gliding flight, the upward aerodynamic force is equal to the weight.In gliding flight, no propulsion is used; the energy to counteract the energy loss due to aerodynamic drag is either taken from the potential energy of the bird, resulting in a descending flight, or is replaced by rising air currents ("thermals"), referred to as soaring flight.
Bird Image Species Family Maximum height Details Rüppell's vulture: Gyps rueppellii: Accipitridae: 11,300 metres (37,100 feet). [1] [2] Vultures use their excellent eyesight to scan the landscape below from a relatively static aerial position. Instead of flying over a larger distance, they use elevation to expand their field of vision. [3]
Kākāpō are the heaviest living species of parrot and on average weigh about 400 g (14 oz) more than the largest flying parrot, the hyacinth macaw. [28] The kākāpō cannot fly, having relatively short wings for its size and lacking the keel on the sternum (breastbone), where the flight muscles of other birds attach. [5]
Parrots have featured in human writings, story, art, humor, religion, and music for thousands of years, such as Aesop's fable "The parrot and the cat", [127] the mention "The parrot can speak, and yet is nothing more than a bird" in The Book of Rites of Ancient China, [128] the Masnavi by Rumi of Persia in 1250 "The Merchant and the Parrot".

English physician, ornithologist, and artist John Latham first described the hyacinth macaw in 1790 under the binomial name Psittacus hyacinthinus. [3] Tony Pittman in 2000 hypothesized that although the illustration in this work appears to be of an actual hyacinthine macaw, Latham's description of the length of the bird might mean he had measured a specimen of Lear's macaw instead.

A wing-clipped Meyer's parrot perching on a drawer handle. While clipping is endorsed by some avian veterinarians, others oppose it. [7]By restricting flight, wing clipping may help prevent indoor birds from risking injury from ceiling fans or flying into large windows, but no evidence shows that clipped birds are safer than full-winged ones, only that clipped birds are subject to different ...
Parrots, also known as psittacines (/ ˈ s ɪ t ə s aɪ n z /), [1] [2] are the 402 species of birds that make up the order Psittaciformes, found in most tropical and subtropical regions, of which 387 are extant. The order is subdivided into three superfamilies: the Psittacoidea ("true" parrots), the Cacatuoidea (cockatoos), and the ...
