Parrots are a group of birds of the order Parrotformes with colorful feathers and love to call.

Parrots are typical climbing birds with anti-toe feet, two toes forward, and two toes back, which are suitable for grasping. Their beaks are strong and they can eat hard-shelled nuts.

Brightly colored, they are often kept as pets. Their beautiful feathers, and good learning of human language skills, for people to appreciate and love.

Parrots are distributed all over the world, distributed in temperate, subtropical, and tropical vast areas. With 2 families, 82 genera, and 358 species, it is one of the largest families of the class Ornithae.

Parrots are most abundant in Latin America and Oceania, with fewer species in Africa and Asia, but in Africa, there are some famous species, such as the grey parrot, the lovebird, and the peony parrot.

The most famous of Latin American parrots is the large macaw. The parrots of Oceania are more diverse than those of Latin America, with opposite-toed toes, the second and third toes pointing forward, and include some of the most familiar, beautiful, and unique parrots.

Australian budgies and sunflower cockatoos are the most familiar parrots. New Zealand's kakapo is a large parrot that has lost its ability to fly, while New Zealand's pecking sheep, which have evolved a carnivorous predisposition, are among the most distributed parrots.

Among the most beautiful birds are Oceania's diverse honey-sucking parrots, such as Fiji's blue-crested honey-sucking parakeets.

The largest parakeet is the purple and blue macaw with a body length of up to 100 centimeters, while the smallest is the blue-crested macaw with a body length of only 12 centimeters.

Most parrots feed on fruit, seeds, nuts, berries, shoots, etc. from trees or ground plants and a small number of insects. The honey-sucking parrots feed on pollen, nectar, and soft, juicy fruits.

Parrots often use their powerful hooked beaks and flexible toes to feed. Antitoe foot, two toes forward and two toes back, suitable for grasping.

When climbing in the tree crown to search for food, first bite the branch with your mouth, and keep up with your feet; When walking on a sturdy tree trunk, insert the tip of your mouth into the tree to balance your body and speed up your movement; When eating, one foot is often used as a "hand" to hold the food and push it into the mouth.

It has been observed that more than 10 kinds of parrots in breeding use the left and right foot frequency in feeding, and found that more than 72% of the individuals use the left foot to catch food.

The comparative anatomy of hindlimb muscles found that those who often grabbed food with their left foot were significantly longer than those who grabbed food with their right foot, and those who made good use of their right foot were only slightly longer than their left foot. There are exceptions.

Take the cockatoo, a large, feathery parrot with a distinctive long, pointed beak that lives in the mountain bushes of Australia and New Zealand. In addition to feeding other parrots but also like to eat insects, crabs, and carrion.

They even jump on the sheep's back and pick at the lamb with their long hard beaks, leaving the live sheep bloody, so the local New Zealand herders also call it a pecker.

With the expansion of human civilization and the development of industrialization, these beautiful birds are also facing the deterioration of the living environment, the population has been sharply reduced, and some species have been or are close to extinction.

The Kakapo of New Zealand is the only nocturnal ground-crawling bird in the Parrotidae family. Originally found in southern New Zealand, Storer, and other islands, they are endangered by rats and weasels in their habitat.

The Tabu honey-suckling parrot, named after the island of Tabuti, is extinct on its ancestral South Pacific island, and despite its true name, only a new introduction from the Cook Islands remains in jeopardy.

The natural enemies of these two kinds of parrots are mice and cats, and they have lived in their native country for thousands of years, and generations, and have few natural enemies. It is the trail of human activity that disrupts the peace here, as ships bring rats and cats to these islands as well as pioneers and travelers.

These killers devour birds' eggs and chicks, driving them to extinction. However, the World Wildlife Conservation Organization moved the survivors to islands with no natural predators and kept them from the public. We will only see these beautiful parrots in pictures and stamps in the future.
