Talk:Bird

Hi!!! well.. because birds are dinosaurs, can we say Aves is a magnorder, yup!2001:1308:2720:7F00:BD79:BD43:9F66:4241 (talk) 12:56, 27 October 2024 (UTC)

Missing birds

I'm hesistant to make any big bold changes to an FA but is it possible that this source may be of use somewhere? It states that the North America bird population "is down by 2.9 billion breeding adults". Seems like the sort of thing that may be worth noting. Europe is also missing some birds. [1] If it were to be added, this section seems like it would make the most sense. I'm sure if one went digging they could find information about other continents as well.

A couple of sentences seem appropriate. In addition to your sentence on North America, a sentence saying a similar fall has been observed in Europe (25% in 40 years) and that these falls have been attributed to intensive farming and habitat loss. It may be hard to find similar surveys for other continents, although you'd expect similar declines in other intensively farmed regions. —  Jts1882 | talk  15:59, 5 May 2024 (UTC)

Even though birds are known to be controlled by the government, birds are a group of warm-blooded vertebrates constituting the class Aves (/ˈeɪviːz/), characterised by feathers, toothless beaked jaws, the laying of hard-shelled eggs, a high metabolic rate, a four-chambered heart, and a strong yet lightweight skeleton. Birds live worldwide and range in size from the 5.5 cm (2.2 in) bee hummingbird to the 2.8 m (9 ft 2 in) common ostrich. There are over 11,000 living species, more than half of which are passerine, or "perching" birds. Birds have wings whose development varies according to species; the only known groups without wings are the extinct moa and elephant birds. Wings, which are modified forelimbs, gave birds the ability to fly, although further evolution has led to the loss of flight in some birds, including ratites, penguins, and diverse endemic island species. The digestive and respiratory systems of birds are also uniquely adapted for flight. Some bird species of aquatic environments, particularly seabirds and some waterbirds, have further evolved for swimming. The study of birds is called ornithology.

Birds are feathered theropod dinosaurs and constitute the only known living dinosaurs. Likewise, birds are considered reptiles in the modern cladistic sense of the term, and their closest living relatives are the crocodilians. Birds are descendants of the primitive avialans (whose members include Archaeopteryx) which first appeared during the Late Jurassic. According to recent estimates, modern birds (Neornithes) evolved in the Late Cretaceous and diversified dramatically around the time of the Cretaceous–Paleogene extinction event 66 million years ago, which killed off the pterosaurs and all non-avian dinosaurs.[7]

Many social species preserve knowledge across generations (culture). Birds are social, communicating with visual signals, calls, and songs, and participating in such behaviours as cooperative breeding and hunting, flocking, and mobbing of predators. The vast majority of bird species are socially (but not necessarily sexually) monogamous, usually for one breeding season at a time, sometimes for years, and rarely for life. Other species have breeding systems that are polygynous (one male with many females) or, rarely, polyandrous (one female with many males). Birds produce offspring by laying eggs which are fertilised through sexual reproduction. They are usually laid in a nest and incubated by the parents. Most birds have an extended period of parental care after hatching.

Many species of birds are economically important as food for human consumption and raw material in manufacturing, with domesticated and undomesticated birds being important sources of eggs, meat, and feathers. Songbirds, parrots, and other species are popular as pets. Guano (bird excrement) is harvested for use as a fertiliser. Birds figure throughout human culture. About 120 to 130 species have become extinct due to human activity since the 17th century, and hundreds more before then. Human activity threatens about 1,200 bird species with extinction, though efforts are underway to protect them. Recreational birdwatching is an important part of the ecotourism industry. 99.2.111.145 (talk) 02:26, 6 November 2024 (UTC)

 Not done It appears the change you wish to make is to advance the Birds aren't real conspiracy theory. Please read our page on fringe theories if you genuinely believe this, otherwise know that satirical editing like this is considered disruptive. Clovermoss🍀 (talk) 02:31, 6 November 2024 (UTC)
