-Bird species: Birds are among the most successful vertebrates on Earth. There are more than 9,000 species of birds, and they are scattered across the planet, from the poles to the equator.

Albatrosses are large birds that spend most of their lives in the sea. Albatrosses are among the largest flying birds in the world. The wandering albatross bird has the longest wingspan of any bird. Their wingspan average about 3 meters (9 feet 10 inches), but there are reports of individuals with a wingspan of more than 5 meters! Wandering albatrosses are famous for covering great distances; Some individuals orbit the Southern Ocean three times in one year.
-Birds of Paradise are known for the elaborate plumage and bright colors of many males. There are 42 species in the bird of paradise family. It is found in eastern Indonesia, Papua New Guinea, and Australia

-There are between 20 and 30 species of trellis birds, with family members in New Guinea and Australia. Trellis are popular courtship rituals. This male bird includes building a very elaborate structure - called the trellis - to dazzle the female. The female is very selective, and will only choose the male whose trellis comes to scratch. Once the mating is complete, the male plays no role in building the nest or raising the young. (The trellis is not used as a nest.)

-The crow family not only contains crows, but also birds such as jays, nutcrackers, crows and magpies. Corvidae members are found on all continents except Antarctica. Crows are among the smartest animals. Several species demonstrated tool use and self-recognition in mirror tests. The common crow is not only the largest member of the crow family, but also the largest passerby. It is as large as - if not slightly larger - than a regular falcon.

-Only a little over 50 of the 140 or so species in the cuckoo family practice brood parasitism, but it is these bad apples that have earned the family its bad reputation. Brooding involves snooping a cuckoo laying its egg in another bird's nest. The nest owners bring the cuckoo chick as one of them, even after it has pushed the other chicks out of the nest.

-The Anatidae family includes between 146 and 160 species. The family is varied, and contains geese, ducks and swans. Most blankets have long necks and legs that bounce against the body for swimming. Male and female ducks often look very different, with males generally having colored feathers, especially during the breeding season. Many blanket birds embark on long migrations to and from their breeding grounds.

-Stubborn is a trumpet swan. It is the heaviest bird in North America, with a wingspan of about 3 m (10 ft).

-There are about 66 species in the Falconidae family, which includes falcons, caracas, and kestrels. Falcons are fast, agile leaflets with pointed wings. Other characteristics include hooked beaks and sharp eyesight. Unlike birds of prey in the Accipitridae family, falcons send their prey with their beaks rather than their claws. Hawk's beak has sharp teeth in its upper jaw for this purpose.

-The peregrine falcon is the fastest moving animal in the world. It has been recorded traveling at 389 km / h (242 mph) while diving.

-Flamingos are long-legged, long-necked birds known for the distinctive pink color of their plumage. This color comes from the pigments found in the food of flamingos. Flamingos feed with their heads upside down, filtering food from the water using comb-like structures in their specially modified bills. The larger flamingo is the largest of the six types of flamingos. It is also the most widespread, being found in Africa, Asia, and southern Europe

-Regulidae are a family of 6 very small birds, whose members are found in North America and Europe. The four types found in Europe are known as gold bars or fire rests. The two species are known in North America as Kinglets. Members of the Regulidae possess brightly colored badges, which can be raised as part of a flirt or threatening display.

-All six species in the Numididae family are found in Africa. Guineas are large, pheasant-like birds that feed on insects and seeds. Guinea fowls live in flocks. They mate for life and nest on land. The guinea helmet bird (Numida milligris) is a common sight in urban areas of South Africa.
