These characteristics include:. Some African grey parrots are able to learn hundreds of words and even can learn to use them to communicate with their owners. Many other animals share some characteristics with birds, but only birds represent all the features above to belong to the Class Aves.
At the same time, all birds are different, and through the million years of evolution since the Mesozoic Era when birds first evolved from reptiles, small differences have created the roughly 10, bird species we enjoy today. Yet with every one of those species, all of these common characteristics are present, making each one a related but distinct bird. Actively scan device characteristics for identification.

A member of the Mammalia class i. You can find out more about what makes a mammal a mammal here: What is a Mammal? Being able to fly is not a defining characteristic of birds: bats are mammals, and they can fly. However, all birds — even flightless birds such as penguins and ostriches — are descended from animals that could fly, and their bodies reflect the adaptations required for flight. By flapping their wings, most birds can take off, glide, and power themselves through the air.
Most birds have lightweight, hollow skeletons to aid flight. Birds have high metabolisms the amount of energy required to live , and have to eat large amounts of food. This is mainly because flying requires a great deal of energy. In addition to lungs, birds have a number of air sacs inside their bodies. This helps to move air in and out of a bird faster.
This too is a necessity due to the high metabolism of birds. If you enjoyed this article, feel free either to share it on social media using the buttons at the top of the page, or link to it from your own website.
But yes, I suppose. Armadillos are mammals — an entirely different, and unrelated, class of animal to reptiles such as crocodiles and alligators and dinosaurs. Alligators are not descendants of dinosaurs. Although alligators and dinosaurs are both reptiles , their ancestors split into two separate evolutionary branches millions of years ago.
You can find out more on this page: Are Dinosaurs Reptiles? Armadillos, despite looking a bit reptilian with their scaly armour, are mammals , not reptiles. Armadillos are definitely not descended from dinosaurs!
Interestingly, the heads of seriemas are similar to heads of hawks. Seriemas are restricted to South America only. Casuariiformes order contains two families of flightless terrestrial birds that are both native to Australia: emus and cassowaries. Previously these herbivorous birds were grouped with Kiwis but later classified into its own order now. These monogamous birds are enormous and heavy up to 55 kgs.
Females are usually larger than males. Charadriiformes is one of the very most extensive bird orders. There are about bird species in it. Surprisingly, these birds have varied in size from 0. As the name suggests, shorebirds live near the water: in wetlands, freshwater and seawater shorelines, sometimes near the ocean.
The next group of birds also live near the water or are fully aquatic is called Ciconiiformes. Most Ciconiiformes have long necks, long beaks, and feet without webbing. The plumage of most species in the order combines most uncomplicated colors — grey, white, and black. Currently, 21 species of Ciconiiformes are seriously threatened. Coliiformes is the smallest bird order which consists of only 6 species of tiny mousebirds. These mousebirds are found in sub-Saharan Africa.
These herbivorous birds are social and often found in small groups. Coliiformes nest in colonies. Columbiformes order embraces both extinct and living species of pigeons or doves , as well as the famous dodos.
The species of this order can be found almost everywhere. Coraciiformes is a diverse and colorful bird order which includes kingfishers, rollers, and bee-eaters. Most of the species spend a significant part of their life on trees. Ornithologists consider rollers the leading family of this order. Cuculiformes is one of the most famous bird orders, as it contains parasitic bird species — cuckoos. These birds place their eggs into the nests of birds of other species, and the hatched chicks destroy all other eggs or chicks in the nest.
Many of the birds in the order are very vocal. Eurypygiformes order contains only a few species, and some of them are already extinct Lowland kagu and Aptornis. Two living species in the order are the New Caledonian endemic kagu and sunbittern. Both the kagu and the sunbittern have plumage with an intricate pattern. Birds in Falconiformes order are highly efficient predators — Falcons. Virtually all these brown-eyed falcons have hooked bills that help tear up the prey. All these birds have well-developed sight and hearing.
Currently, many Falconiformes species are endangered. This large and diverse group of birds in order Galliformes includes species traditionally crucial to humans as domestic birds and hunting fowl Chickens and Turkeys.
Many Galliformes have bright crests and ornamental tails. This next types of birds belong to order Gaviiformes which contains several species of birds that live and hunt on the water — Loons.
These sturdy webbed feet birds swim on the water to eat fish. Interestingly, the feet of loons are placed closer to their tails, so they have difficulty walking on land!
Gruiformes order contains very diverse birds, both in size and other features. Most important species of Gruiformes are cranes and quails, but there also other less known species. These birds are known for special mating rituals! Cuckoo roller belongs to an exclusive bird order — Leptosomiformes which contains just this bird species. Cuckoo rollers live in the Comoro Islands and Madagascar.
Surprisingly, the eyes of cuckoo rollers are set back in the face. These birds live primarily in forests and feed on insects. Mesitornithiformes order contains three species of Mesites found only in Madagascar. They are related to doves. Mesites are small birds. Mesites are nearly flightless and spend most of the time on land. Currently, all mesites are endangered. The next bird order Musophagiformes contains birds that are found in sub-Saharan Africa, namely turacos and plantain eaters.
Musophagiformes have a long tail compared to the overall body length. All of the birds in the order have a crest on their heads. Previously, it was thought that Hoatzins was related to Galliformes , but recently they were assigned to a separate order — Opisthocomiformes. The faces of hoatzins are bare and are blue. These herbivorous Hoatzins have a crest on their heads that resembles a fan! The birds of the order Otidiformes may belong to the bigger clade Gruiformes in some classifications.
However, these birds Bustards have several conspicuous characteristics, from appearance to behavior, that place them apart. Animal Diversity Web Cybertracker Tools. All rights reserved. Skip directly to main content. Kids' Inquiry of Diverse Species. Critter Catalog.
