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 May 23, 2022 at 3:55 pm

    On cold, dark winter mornings, small black crows known as jackdaws can be heard calling loudly to one another from their winter roosting spots in the U.K. before taking off simultaneously right around sunrise. Now, researchers who've studied their daily activities in unprecedented detail report evidence that these groups of hundreds of individuals rely on a 'democratic' decision-making process to coordinate with one another and take to the skies all at once.

    A new study takes a data-driven look at influenza viruses circulating among different groups of birds and characterizes which types of birds are involved in spreading the virus. This paper publishes at a time when a highly pathogenic strain of avian influenza has been spreading across North America.

    Many animal species bury their eggs, for a number of different reasons. While it is firmly established that Eurasian penduline tits bury them because of sexual conflict, their Chinese counterparts seem to have an entirely different reason. Experimental manipulations show that for these birds burial prevents the eggs from falling out of the nest in strong winds.

    One of the most exciting moments of the new Jurassic Park sequel, "Jurassic World Dominion," is when the Quetzalcoatlus swoops down from the sky and attacks the heroes' aircraft. With its gigantic wings reaching 10 meters in length end to end, the Quetzalcoatlus was the largest pterosaur that ever existed. However, an aerodynamic analysis led by researchers from Nagoya University suggests that "Jurassic World Dominion" gets it wrong. In fact, these giant creatures would have been unable to fly […]
