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

Researchers from the Institute of Evolutionary Biology (IBE, a joint institute of the Pompeu Fabra University (UPF) and the Spanish National Research Council (CSIC)) in Barcelona and the Globe Institute at the University of Copenhagen have unveiled the genome of the Carolina parakeet, declared extinct at the beginning of the 20th century. Researchers explored the genome for signs found in endangered species but did not find them, suggesting that Carolina parakeet extinction was an abrupt […]

I am a survivor of the Bhopal gas tragedy, which is considered to be the world's worst industrial disaster. By writing this piece, I will do what most residents of the city of Bhopal dislike doing, which is to relive the tragedy. But even though many years have passed, I must write about it because I have an important story to tell, and because we can learn from it when dealing with today's environmental disasters and the climate crisis.

In a neighborhood on the outskirts of Miami, a red-bellied woodpecker made two individual nests in two neighboring dead palm trees. It picked one. A red-masked parakeet moved into the other. Over the summer, they shared alarm calls when strangers approached. They would fly to the same tree when Joshua Diamond examined their nests. This was when he learned they were both parents, raising their young, side by side, without any competition or interference.
