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
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
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

Researchers have found that the benefits of migration have been eroded by the effects of climate change and human pressure.
- Mixed results from sage grouse hunting...on October 12, 2021 at 5:07 pm
Wildlife agencies throughout western North America have set increasingly more conservative harvest regulations over the past 25 years to conserve sage grouse, with mixed results for bird numbers.
- Birds learn to avoid plants that host dangerous...on October 7, 2021 at 4:20 pm
Scientists have discovered that birds know to avoid the plants where toxic animals dwell.
- Feather phenomenon: Radar indicates stronger...on October 6, 2021 at 6:34 pm
Whether birds get caged in the eye of a hurricane may depend on the intensity and totality of the chaos beyond the calm, says a novel study.
- Smart parrots need more stimulationon October 5, 2021 at 11:09 pm
The smarter the bird, the more unique welfare needs it has in captivity, according to a new study that helps to explain why many intelligent animals struggle in captivity. The findings are also important to owners of intelligent birds to ensure they provide them with naturalistic diets rather than processed foods.

Modern snakes evolved from ancestors that lived side by side with the dinosaurs and that likely fed mainly on insects and lizards.
- Growing dominance of diatom algae in the Pearl...on October 14, 2021 at 3:41 pm
It is a common perception that waters close to population would be more polluted than those offshore or at higher latitudes. However, researchers from The Hong Kong University of Science and Technology (HKUST) found that the ratio between two common microalgae diatom and dinoflagellate (dino) – a common benchmark of water quality, has been nearly doubled in the Pearl River Estuary (PRE), one of the world's most urbanized subtropical coastal waters, over the past two decades.
