Encyclopedia
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

- Clever cockatoos learn through social interactionon July 22, 2021 at 6:00 pm
For the first time, a team of international scientists have proven that cockatoos, an iconic Australian bird species, learn from each other a unique skill—lifting garbage bin lids to gather food. The world-first research published today in Science, confirms that cockatoos spread this novel behavior through social learning. Led by Barbara Klump and Lucy Aplin (Max Planck Institute of Animal Behavior), along with John Martin (Taronga Conservation Society) and Richard Major (Australian Museum), […]

New data on macaw movements gathered by the Texas A&M University College of Veterinary Medicine & Biomedical Sciences' (CVMBS) The Macaw Society has the potential to greatly improve conservation strategies for the scarlet macaw, as well as similar species of large parrots.
- Parrot talk can lead to flockon June 17, 2021 at 4:26 pm
During flock encounters, a single vocal interaction seems to be sufficient for making the decision of whether to recruit an individual or flock. Parrots are known for their splendid ability to imitate, including the contact calls of other individuals during vocal interactions. Such rapid vocal matching is hypothesized to precede and mediate the formation of new flocks. But how are such interactions perceived by others?
