Encyclopedia

Birds, also known as Aves, are a group of endothermic vertebrates, 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 cm (2 in) bee hummingbird to the 2.75 m (9 ft) ostrich. They rank as the world’s most numerically-successful class of tetrapods, with approximately ten thousand living species, more than half of these being passerines, sometimes known as perching birds. Birds have wings which are more or less developed depending on the species; the only known groups without wings are the extinct moa and elephant birds. Wings, which evolved from forelimbs, gave birds the ability to fly, although further evolution has led to the loss of flight in flightless birds, including ratites, penguins, and diverse endemic island species of birds. 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. — Wikipedia

Science

Ornithology is a branch of zoology that concerns the study of birds. Several aspects of ornithology differ from related disciplines, due partly to the high visibility and the aesthetic appeal of birds. Most marked among these is the extent of studies undertaken by amateurs working within the parameters of strict scientific methodology.

The science of ornithology has a long history and studies on birds have helped develop several key concepts in evolution, behavior and ecology such as the definition of species, the process of speciation, instinct, learning, ecological niches, guilds, island biogeography, phylogeography, and conservation. While early ornithology was principally concerned with descriptions and distributions of species, ornithologists today seek answers to very specific questions, often using birds as models to test hypotheses or predictions based on theories. — Wikipedia

    on September 22, 2022 at 2:31 pm

    Researchers have conducted a new analysis of the origins of 'bird-hipped' dinosaurs -- the group which includes iconic species such as Triceratops -- and found that they likely evolved from a group of animals known as silesaurs, which were first identified two decades ago.

    The impact of the rise in sea temperatures predicted by the Intergovernmental Panel on Climate Change (IPCC) could affect the survival of the North Atlantic populations of Bulwer's petrel in the Azores, Canary Islands and Cape Verde, according to a new study.

    on September 20, 2022 at 6:54 pm

    Researchers have found regions in the woodpecker forebrain that show characteristics that until now have only been associated with vocal learning in animals and language in humans. The study shows that instead of being related to vocalization, activity in these brain regions is related to the characteristic tree drumming that gives woodpeckers their name.

  • Pythons are true choke artists
    on September 16, 2022 at 8:17 pm

    Biologists have found that it's not just the size of its head and body that puts almost everything on a Burmese python's menu. They evolved super-stretchy skin between their lower jaws that allows them to consume prey up to six times larger than similar-sized snakes.

  • How songbirds' striking colors put them at risk
    on September 15, 2022 at 4:37 pm

    Bright, uniquely colored songbirds are at higher risk of extinction and more likely to be traded as pets. Researchers also predict that almost 500 additional bird species, most of them living in the tropics, are at risk of future trade based on their unique and desirable coloration.

    The Biden administration on Thursday proposed a new permitting program for wind energy turbines, power lines and other projects that kill eagles, amid growing concern among scientists that the rapid expansion of renewable energy in the U.S. West could harm golden eagle populations now teetering on decline.

    An international team of researchers have sounded new alarm bells about the changing chemistry of the western region of the Arctic Ocean after discovering acidity levels increasing three to four times faster than ocean waters elsewhere.

  • Study finds less bird diversity in city forests
    on September 29, 2022 at 5:14 pm

    A new study led by Lund University in Sweden shows that cities negatively affect the diversity of birds. There are significantly fewer bird species in urban forests compared with forests in the countryside—even if the forest areas are of the same quality.

    For all the vastness of our Outback and bush, most Australians live in urban areas. In cities, we live within an orderly landscape, molded and manufactured by us to suit our needs. But other species also live in this modified environment.
