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

Conservation action has prevented the global extinction of at least 28 bird and mammal species since 1993, a study led by Newcastle University, UK and BirdLife International has shown. The species include Puerto Rican Amazon Amazona vittata, Przewalski's Horse Equus ferus, Alagoas Antwren Myrmotherula snowi, Iberian Lynx Lynx pardinus, and Black Stilt Himantopus novaezelandiae, among others.

So far, the majority of studies investigating brain functions and intelligence have been carried out either on humans or animals that are known to be most similar to humans, such as monkeys, apes, and other mammals. Nonetheless, some avian species, including corvids and parrots, also have sophisticated and surprising cognitive skills, which are sometimes comparable to those of large-brained mammals.

Bird and reptile tears aren't so unlike our own, shows a new study in Frontiers in Veterinary Science. But the differences could provide insights into better ophthalmic treatments for humans and animals, as well as a clues into the evolution of tears across different species.
