Dictionary

bird : any of a class (Aves) of warm-blooded vertebrates distinguished by having the body more or less completely covered with feathers and the forelimbs modified as wings — Webster   See also   OneLook

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 methodological study and consequent knowledge of birds with all that relates to them. A wide range of tools and techniques are used in ornithology, both inside the laboratory and out in the field. Most biologists who consider themselves to be “Ornithologists” study specific categories, such as Anatomy, Taxonomy, or Ecology lifestyles and behaviors. — Wikipedia

  • New research turns what we know about bird window...
    on February 2, 2023 at 1:18 pm

    New research reveals that decals intended to reduce incidents of bird window strikes -- one of the largest human-made causes of bird mortality -- are only effective if decals are placed on the outside of the window. Researchers found that the patterns on the films and decals placed on the internal surface of windows do not reduce collision because they may not be sufficiently visible to birds.

    Computer scientists recently announced a new, predictive model that is capable of accurately forecasting where a migratory bird will go next -- one of the most difficult tasks in biology. The model is called BirdFlow, and while it is still being perfected, it should be available to scientists within the year and will eventually make its way to the general public.

    Plants and animals do not respect legal boundaries, oblivious to the policies that govern different jurisdictions. A new Stanford-led study highlights how policies in forestry, agriculture, and other sectors can fit together to govern biodiversity in a more coordinated and effective way. Published Feb. 6 in Nature Ecology & Evolution, the first of its kind analysis focuses on Colombia, one of the world's most biodiverse countries, finding that biodiversity is governed by almost 200 distinct […]

    Arthropods crawl and buzz around us in the wild and on farmlands, on the street and at home, under our floors and in our plumbing systems, even in our food and on our bodies. But while we often are inconvenienced by this group of invertebrates—which comprises more than a million species, including all insects—their absence would be catastrophic: Arthropods are ecosystem engineers that pollinate our crops, turn over agricultural soils and sustain an enormous diversity of predators, from […]
