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 — Merriam-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

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

- When pigeons dreamon June 6, 2023 at 3:17 pm
Dreams have been considered a hallmark of human sleep for a long time. Latest findings, however, suggest that when pigeons sleep, they might experience visions of flight. Researchers studied brain activation patterns in sleeping pigeons, using functional magnetic resonance imaging. The study revealed that similar to mammals, most of the brain is highly active during REM sleep. However, this wake-like state might come at a cost of reduced waste removal from the brain.
- Forest birds with short, round wings more...on June 1, 2023 at 7:59 pm
Tropical forest birds, which tend to have wings that are short and round relative to their body length and shape, are more sensitive to habitat fragmentation than the long-, slender-winged species common in temperate forests.
- Genetic change increased bird flu severity during...on May 31, 2023 at 12:30 am
Scientists found the virus strains that arrived in 2021 soon acquired genes from viruses in wild birds in North America. The resulting reassortant viruses have spread across the continent and caused more severe disease.
- Dinosaurs were the first to take the perspectives...on May 22, 2023 at 5:13 pm
Understanding that others hold different viewpoints from your own is essential for human sociality. Adopting another person's visual perspective is a complex skill that emerges around the age of two. A new study suggests that this ability first arose in dinosaurs, at least 60 million years before it appeared in mammals. These findings challenge the idea that mammals were the originators of novel and superior forms of intelligence in the wake of the dinosaur extinction.
- Perfection: The Enemy of Evolutionon May 18, 2023 at 9:20 pm
Evolution is a sequence of design changes happening on their own in a discernible direction; it never weds itself to a single point on a drawing board. An evolving system or animal is free to simply go with what works. Not so much that its performance suffers greatly, but enough that it opens access to other options near the so-called optimal design. With scientists often looking to nature for clues to solve challenges, they should also free to miss the optimal mark and open a wider design […]

An insect that can be hazardous to human health is spreading across southeast England.
- New study takes a high-level look at Nazca...on June 9, 2023 at 5:27 pm
Nazca boobies can live to 28 years of age, but in their late teens, their ability to raise chicks declines substantially. Why their breeding drops in old age has plagued Wake Forest University Professor of Biology David Anderson for years. But a new study, published in Ecology and Evolution, may help answer the question, by looking at their ability to forage, or search for and capture food.
- Researchers discover 12,000-year-old flutes made...on June 9, 2023 at 2:30 pm
A team of researchers, including a Virginia Commonwealth University professor, has discovered rare prehistoric instruments made from the bones of birds dating back more than 12,000 years, according to findings published Friday in the journal Scientific Reports.

Professional forager Dave Odd confidently declared he could start a Sunday tour at Wilson Skate Park by identifying five edible plants right underneath his feet. Taking a step forward, he pointed to a dandelion and called it "the most obvious" edible plant.

An early bird El Nino has officially formed, likely to be strong, warp weather worldwide and give an already warming Earth an extra kick of natural heat, meteorologists announced.
