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

Bloody hell! That cockatoo just opened my bin, and it's eating my leftover pizza. We can't have that, I'll put a rock on the lid to stop it opening the bin. Problem solved…?
- How songbirds' striking colors put them at riskon September 15, 2022 at 3:00 pm
Bright, uniquely colored songbirds are at higher risk of extinction and more likely to be traded as pets, according to researchers reporting in Current Biology on September 15. The researchers also predict that almost 500 additional bird species, most of them living in the tropics, are at risk of future trade based on their unique and desirable coloration.
- In Australia, cockatoos and humans are in an arms...on September 12, 2022 at 3:00 pm
Residents of southern Sydney, Australia have been in a long-term battle over garbage—humans want to throw it out, and cockatoos want to eat it. The sulfur-crested cockatoos that call the area home have a knack for getting into garbage bins, and people have been using inventive devices to keep them out. Researchers detail the techniques used by both people and parrots in a study publishing on September 12 in the journal Current Biology.

- False balance in news coverage of climate change...on July 22, 2022 at 6:10 pm
What does media coverage of climate change have in common with coverage of COVID-19? Each has been an example of the media practice of "bothsidesism," whereby journalists strive to present both sides of an issue, even in cases where most credible sources fall on one side.
