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

Past is prologue: Genetic 'memory' of ancestral...

Organisms carry long-term 'memories' of their ancestral homelands that help them adapt to environmental change, according to a new study that involved raising chickens on the Tibetan Plateau and an adjacent lowland site.
Microplastics found in Florida's birds of prey...
on May 20, 2020 at 4:49 pm
A new study has confirmed and quantified, for the first time, the presence of microplastics in terrestrial and aquatic birds of prey in Florida, including hawks, ospreys and owls. The research is important because birds of prey are critical to a functioning ecosystem. The accumulation of microplastics in their digestive systems could lead to poisoning, starvation and death.
Hunting threatens one of the world's most amazing...

As the world looks to tighten up the illegal capture of wildlife, migratory birds are being threatened by widespread and unsustainable hunting across the Asia-Pacific region. New research has revealed that three quarters of migratory shorebird species in the region have been hunted since the 1970s.
Researchers go cuckoo: Antarctic penguins release...
on May 19, 2020 at 3:42 pm
In a new study, researchers from the University of Copenhagen have demonstrated that penguins in Antarctica emit copious amounts of nitrous oxide via their feces. So much so, that the researchers went ''cuckoo'' from being surrounded by penguin poop.
How do birds understand 'foreign' calls?
on May 19, 2020 at 3:42 pm
New research show that the coal tit (Periparus ater) can eavesdrop and react to the predatory warning calls of the Japanese tit (Parus minor) and evokes a visual image of the predator in their mind.

For the first time in over a decade, endangered Ohlone tiger beetles roam a preserve near Soquel and await their chance to pounce on unsuspecting prey. Their metallic emerald bodies appear iridescent in the sunlight as they scurry across the bare earth.

The third week of May, Agricultural Research Service (ARS) scientists Doris Lagos-Kutz and Glen Hartman venture to a nearby field to set a timer on a smokestack-like device that rises 20 feet into the air and serves a single purpose: to capture winged insects such as aphids (notably, soybean aphids), thrips and other potential soybean pests.

After a severe drought gripped the Prairie Pothole Region of the U.S. and Canada in the 1980s, populations of almost all dabbling duck species that breed there have recovered. But not northern pintails. Now, a new study by a team of researchers suggests why—they have been caught in an ecological trap.
Wading birds: shorebirds with unusual social...
on May 28, 2020 at 2:25 pm
,Waders like wet conditions. They look for insects and other creepy-crawlies in the damp earth. Some species, such as the Mexican snowy plover or the ruff have developed fascinating behavioural patterns. Clemens Küpper and his working group at the Max Planck Institute for Ornithology in Seewiesen is conducting long-terms studies of the social behaviour of these birds. Here, the issue of biodiversity is central, since like many groups of bird species, the numbers of wading birds are in […]
