parrot : any of numerous widely distributed tropical birds (order Psittaciformes and especially family Psittacidae) that are often crested and brightly colored, have a distinctive stout hooked bill and zygodactyl feet, and include some excellent mimics — Webster
Parrots, also known as psittacines, are birds of the roughly 393 species in 92 genera that make up the order Psittaciformes, found in most tropical and subtropical regions. The order is subdivided into three superfamilies: the Psittacoidea (“true” parrots), the Cacatuoidea (cockatoos), and the Strigopoidea (New Zealand parrots). Parrots have a generally pantropical distribution with several species inhabiting temperate regions in the Southern Hemisphere, as well. The greatest diversity of parrots is in South America and Australasia.
Characteristic features of parrots include a strong, curved bill, an upright stance, strong legs, and clawed zygodactyl feet. Many parrots are vividly coloured, and some are multi-coloured. Most parrots exhibit little or no sexual dimorphism in the visual spectrum. They form the most variably sized bird order in terms of length. The most important components of most parrots’ diets are seeds, nuts, fruit, buds, and other plant material. A few species sometimes eat animals and carrion, while the lories and lorikeets are specialised for feeding on floral nectar and soft fruits. Almost all parrots nest in tree hollows (or nest boxes in captivity), and lay white eggs from which hatch altricial (helpless) young.
Parrots, along with ravens, crows, jays, and magpies, are among the most intelligent birds, and the ability of some species to imitate human voices enhances their popularity as pets. Trapping wild parrots for the pet trade, as well as hunting, habitat loss, and competition from invasive species, has diminished wild populations, with parrots being subjected to more exploitation than any other group of birds. — Wikipedia

More animal species under threat of extinction,...
on January 17, 2019 at 2:12 pm
Currently approximately 600 species might be inaccurately assessed as non-threatened on the Red List of Threatened Species. More than a hundred others that couldn't be assessed before, also appear to be threatened. A new more efficient, systematic and comprehensive approach to assess the extinction risk of animals has shown this. The method, designed by Radboud University ecologist Luca Santini and colleagues, is described in Conservation Biology on January 17th. […]
Cop voice: Jay-Z, Public Enemy songs highlight...
on January 16, 2019 at 7:49 am
What do songs by artists like Jay-Z and Public Enemy have in common? They feature representations of 'cop voice,' a racialized way of speaking that police use to weaponize their voices around people of color, according to faculty at Binghamton University, State University of New York. […]
'Alexa, call my lawyer!' Are you legally liable...

When Amazon launched its Alexa virtual assistant in 2014, it probably didn't think that a bird would expose a potentially significant legal issue with the device. But an African grey parrot named Rocco, living in Blewbury, England, appears to have done just that. […]
Intelligent males may make female birds swoon:...

Male birds are often the ones with the most vibrant feathers, or the most elaborate songs, but researchers said Thursday that what female birds could really appreciate is a male who shows his intelligence. […]
What makes two species different?
on January 3, 2019 at 5:36 pm
Most evolutionary biologists distinguish one species from another based on reproductivity: members of different species either won't or can't mate with one another, or, if they do, the resulting offspring are often sterile, unviable, or suffer some other sort of reduced fitness. […]
