about birds in english

People also use falcons for hunting, and cormorants for fishing. Females are generally the ones that drive partner selection,[195] although in the polyandrous phalaropes, this is reversed: plainer males choose brightly coloured females. If a flock of birds were flying over a field, they would be calling "Fly! [139] Other birds are scavengers; some of these, like vultures, are specialised carrion eaters, while others, like gulls, corvids, or other birds of prey, are opportunists. They lay hard-shelled eggs. That means that the cuckoo has the whole care of both parents. [115] As a general rule, the tail feathers are moulted and replaced starting with the innermost pair. (2020)[49], Caprimulgiformes (swifts, hummingbirds, nightjars and allies), Procellariiformes (albatrosses and petrels), Pelecaniformes (pelicans, herons & ibises), Coraciiformes (kingfishers and relatives), The classification of birds is a contentious issue. The scales of birds are thought to be homologous to those of reptiles and mammals. [181] Communal roosting is common because it lowers the loss of body heat and decreases the risks associated with predators. [180], Some birds have also demonstrated the capacity to fall into slow-wave sleep one hemisphere of the brain at a time. This is not always the case. Sometimes the calls are longer and more musical. Many groups retained primitive characteristics, such as clawed wings and teeth, though the latter were lost independently in a number of avialan groups, including modern birds (Aves). As both species are small aerial and canopy foraging omnivores, a similar ecological niche was inferred for this hypothetical ancestor. The other 25% of the air goes directly into the lungs. Birds live worldwide and range in size from the 5 cm (2 in) bee hummingbird to the 2.75 m (9 ft) ostrich. Generally, currawongs from the Blue Mountains are the finest singers. [179] It has been suggested that there may be certain kinds of sleep which are possible even when in flight. [26], The Late Jurassic Archaeopteryx is well known as one of the first transitional fossils to be found, and it provided support for the theory of evolution in the late 19th century. [54], Birds live and breed in most terrestrial habitats and on all seven continents, reaching their southern extreme in the snow petrel's breeding colonies up to 440 kilometres (270 mi) inland in Antarctica. This explains why one might say birds are living dinosaurs. Some birds put the eggs inside or on top of the mound of leaves and twigs. Whittow, G. (2000). Enantiornithes occupied a wide array of ecological niches, from sand-probing shorebirds and fish-eaters to tree-dwelling forms and seed-eaters. In natural populations of Parus major, inbreeding is avoided by dispersal of individuals from their birthplace, which reduces the chance of mating with a close relative.[228]. Mesozoic bird phylogeny simplified after Wang et al., 2015's phylogenetic analysis. [275] The relationship between an albatross and a sailor is the central theme of Samuel Taylor Coleridge's The Rime of the Ancient Mariner, which led to the use of the term as a metaphor for a 'burden'. Flight is the primary means of locomotion for most bird species and is used for searching for food and for escaping from predators. Guano (bird excrement) is harvested for use as a fertiliser. Birds are social. Darwin's finch Geospiza scandens experiences inbreeding depression (reduced survival of offspring) and the magnitude of this effect is influenced by environmental conditions such as low food availability. Species that are victims of brood parasites have varying egg colours to improve the chances of spotting a parasite's egg, which forces female parasites to match their eggs to those of their hosts.[201]. The spine has cervical, thoracic, lumbar and caudal regions with the number of cervical (neck) vertebrae highly variable and especially flexible, but movement is reduced in the anterior thoracic vertebrae and absent in the later vertebrae. Once the birds have found partners, they find a suitable place to lay eggs. Most birds have a poor sense of smell[95] with notable exceptions including kiwis,[96] New World vultures[97] and tubenoses. The other part of the stomach is the gizzard. [236], Birds are often important to island ecology. [192] Males of species that engage in extra-pair copulations will closely guard their mates to ensure the parentage of the offspring that they raise.[193]. Lorenz was sure that it was her long-lost "husband" who had found his way home at last.[11]. "Vertebrate Circulation". In: K. Padian, ed. Palaeontologists now agree that birds evolved from Maniraptora group of dinosaurs. Most usually it is the chicken and its eggs, but people often also eat geese, pheasants, turkeys and ducks. When the bird exhales, the used air flows out of the lungs and the stored fresh air from the posterior air sac is simultaneously forced into the lungs. [164] Variation in plumage also allows for the identification of birds, particularly between species. [66] Avian foraging strategies can vary widely by species. Incubation can be an energetically demanding process; adult albatrosses, for instance, lose as much as 83 grams (2.9 oz) of body weight per day of incubation. Those species that seek pest insects are considered beneficial 'biological control agents' and their presence encouraged in biological pest control programmes. Crows and ravens often perch high on bare trees in the winter, where their black shape against the sky looks like the dark bare branches. Many species of the second major avialan lineage to diversify, the Euornithes (meaning "true birds", because they include the ancestors of modern birds), were semi-aquatic and specialised in eating fish and other small aquatic organisms. Some birds, especially crows and parrots, are among the most intelligent animals. Large birds of prey, such as eagles, that spend a lot of time soaring on the wind have wings that are large and broad. Most male birds have no sex organs that can be seen. Most pet birds are specially bred and are sold in pet shops. This osprey at Kennedy Space Centre is hovering. Many species will spread out their wings and expose them to direct sunlight and this too is thought to help in reducing fungal and ectoparasitic activity that may lead to feather damage. [3], The Cretaceous–Palaeogene extinction event 66 million years ago killed off all the non-avian dinosaur lines. [124] Flightlessness often arises in birds on isolated islands, probably due to limited resources and the absence of land predators.
