At first glance, it looks like an eagle beak, but from the comparison in the picture, it can be seen that the eagle beak has a strong upper beak and a weak lower beak, which is mainly used to tear prey like a hook and has no strong bite force; The parrot's mouth is very strong, and its upper and lower beaks are very strong. The masseter muscle on its cheek is also well developed, with a strong bite force and a structure like pliers. Except for a few species such as the sheep-pecking parrot, parrots are almost all vegetarians. The pliers-like mouth is a sharp weapon against hard fruit shells. Although its bite force and actual destructive power are far better than that of raptors, parrots are carnivores in nature and will not attack actively, so they are "sheep with lion teeth". Of course, when in an awkward situation, they will also bite people to defend themselves, and large species will even hurt people. Keep large and medium-sized parrots at home, remember not to provoke their aggression at will.

Parrot's tongue is fleshy and has an eraser-like texture, which is significantly different from other birds.

Many people think that this structure of the tongue is an advantage for parrots to learn to speak. Actually, it is not. It has been proved by science that the tongue is not a vocal organ, but an auxiliary organ for synthesizing certain syllables. Parrot's tongue doesn't even have the function of assisting pronunciation. They can "talk" with their mouths full without opening their mouths. Parrot's tongue has two main functions: it is used as a pestle when crushing food (the lower beak is used as a container for holding food), and it is used as a detection tool when exploring objects, which is equivalent to a human index finger.

Their tongues have tough connective tissues and abundant nerve endings, which can sensitively sense the soft and hard texture and temperature of objects. Curious parrots, especially young birds, often lick people's fingers, which is equivalent to a puppy sniffing around at the back of your feet, but it doesn't mean it wants to bite you. It is said that parrots have a poor sense of taste (as birds usually do) and it is difficult to tell the ups and downs of food. Captive parrots prefer sweets (that's because humans always choose sweet things as food), while many parrots living in the wild often eat bitter fruits. Some parrots bred purely artificially may not be able to distinguish food. They may eat soft plastics and other food-like things, even moles on their fingers and skin!

Parrots are also the most colorful birds.

Almost all colors in nature are reflected in them: bright red, golden yellow, green and sky blue, pure white, dark gray and dark color, and even cinnamon, blue purple and crimson, which are rare in birds, are not uncommon. This is because parrots are widely distributed, with diverse living environments and special feather structures. The feathers of several common parrots in China are mostly green, so we call them "red-billed green Ying Ge". With the increase of foreign exchange, we will come into contact with more exotic species with the same color as flowers.

Parrot is a recognized classification, of course, there are other special features, such as toes distributed relatively before and after, which are more suitable for climbing trees; Developed crops in the esophagus can store and digest more food; Breeding habits of nesting and foraging in tree holes; The funny expression of eating with food in their feet ... and what they say most is their cleverness-being good at imitation and imitation. So parrots are also the earliest ornamental animals raised by human beings. In China, a book "The Book of Rites" was written about two years ago, in which it was described that "parrots can talk without birds".
