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

The Vertebrate Genomes Project (VGP) today announces their flagship study and associated publications focused on genome assembly quality and standardization for the field of genomics. This study includes 16 diploid high-quality, near error-free, and near complete vertebrate reference genome assemblies for species across all taxa with backbones (i.e., mammals, amphibians, birds, reptiles, and fishes) from five years of piloting the first phase of the VGP project.

New research from The Australian National University (ANU) shows female swift parrots can determine the sex of their offspring, and they are favoring boys over girls as they face diminished survival prospects in the wild.

Ancient Egyptians mummified cats, dogs, ibises and other animals, but closer to home in the South American Atacama desert, parrot mummies reveal that between 1100 and 1450 CE, trade from other areas brought parrots and macaws to oasis communities, according to an international and interdisciplinary team.
- Ant invasion: How pets become pestson March 29, 2021 at 2:40 pm
When I was a teenager, I volunteered in the rainforest exhibit at an aquarium. A few times a week, we'd get a phone call from someone looking to donate a pet that they could no longer care for. Mostly turtles and frogs. The occasional parrot. Once, a retired dancer wanted to find a new home for two boa constrictors that had been part of her act.

Islands are biodiversity hotspots. They are home to 20% of the world's plants and animals yet cover only 5% of the global landmass. But island ecosystems are highly vulnerable, threatened by habitat fragmentation and introduced invasive weeds and predators.
