1. Kingfisher

Kingfishers have a cosmopolitan distribution, with most species found in tropical regions of Africa, Asia and Oceania, but can also be seen in Europe. They can be found in deep forests near calm ponds and small rivers. The family has 114 species, divided into three subfamilies and 19 genera. All kingfishers have large heads, long, pointed beaks, short legs and stubby tails. Most species have bright plumage with only small differences between the sexes. Most species are found in the tropics, and a few are found only in forests.

2. Keel-billed Toucan

The keel-billed toucan is a large bird with mostly black plumage and a very large, multicolored beak. It has red and white coverts under and above its tail, green skin and legends around the eyes (the area between the eyes and beak), a yellow face and throat, and blue legs. A toucan's beak looks heavy, but it's actually quite light. It is hollow, made of the protein keratin, and has thin bone rods for support. Although scientists have yet to discover the exact function of their large beak, they believe it may play an important role in courtship displays and defensive weapons.

3. Cardinal Bird

The bright red covers most of their bodies and can act as a sign of good health, allowing females to choose only the least disease-free, most vigorous males as potential mates. Adult males are bright red with a black face covering extending to the top of the thighs. On the back and wings, the color becomes more dull and dull. The female body color is weak, mostly gray-brown, and the body side, crest, and tail feathers are slightly reddish.

Cockatoos are characterized by a prominent crown and curved beak. Their plumage is generally not as colorful as other parrots, being predominantly white, grey or black, and often has colored features on the crest, cheeks or tail. Cockatoos' calls are loud and piercing. They have a variety of functions, including allowing individuals to recognize each other, warning other predators, indicating individual emotions, keeping the flock cohesive, and serving as a warning when protecting the nest.

5. Nicobar pigeon

Unfortunately, as a close relative of the extinct dodo, it is the only living member of the genus Caloenas. Fortunately, it exists and we are doing our best to keep these birds safe, they are nature's precious creations. It is a large pigeon with a body length of 40 cm. The head is grey, like the feathers on the lower part of the neck turning green and cotton down. The tail is pure white and very short. Most of its feathers are green and blue.

6. Mandarin Duck

Under the rule of ducks, mandarin ducks are the most beautiful ducks in existence, rich in color, large in number, and varied. The world of mandarin ducks has a strict monogamy system, and paired mandarin ducks also symbolize beautiful love. Male species create their beauty.

Various mutations have been found, but the most common is the white mandarin duck. Male mandarin ducks have the most delicate and gorgeous plumage, with bright orange long feathers on the sides of the face, orange "sails" on the back, and pale orange on the sides. Compared to the grey head and white stripes on the back, the female mandarin duck is much inferior.
