Birds Facts
Birds, members of the class Aves, include more than 10,400 living bird species – more than half being passerine, or “perching” birds. Their feathers distinguish them from all other classes of animal; no other animals on earth have them.
Beautiful to behold and charming to watch, there are many different types of birds that are often kept as pets by humans, and are the subject of many a story or photograph. Birdwatchers number in the millions while bird feeding is a multi-million dollar industry made possible by human beings’ love of our feathered friends.
If you see an animal with feathers, it’s undoubtedly a bird. Like mammals, birds are warm-blooded vertebrates with four-chambered hearts. However, birds are more closely related to reptiles and are believed to have evolved from dinosaurs. Their closest living relatives are the crocodilians.
Their forelimbs have been modified into wings over many millions of years of evolution, they lay hard-shelled eggs and they have exceptional vision – the most acute of their senses. Most types of bird species are diurnal, meaning they sleep at night.
Different types of birds may display different behaviors, though in general, birds are social creatures, communicating with songs, calls, chirps and movements. Some birds participate in cooperative hunting and travel in flocks. Many birds are monogamous – mostly for a breeding season but sometimes for life.
Most birds can fly, but flightless bird species exist.
The deep green common magpie is a carnivore who eats anything it can get its beak on, including dead animals and bird eggs.

Five Top Bird Characteristics
Certain identifying characteristics distinguish different types of birds from other classes of animals. Five especially important distinguishing characteristics of birds include:
Feathers
All birds species have feathers, which are actually highly evolved scales. In fact, birds have scales on their feet – the clearest reminder of their close relation to reptiles. As noted above, feathers are not found on any other class of animal. Like nails and hair on humans, feathers are made out of keratin. They serve a number of purposes, from providing warmth to assisting in the ability to fly. Most species of birds shed, or molt, their feathers one or two times per year. Contour feathers help birds to fly effectively and create a streamlined body shape. Soft, fluffy feathers provide warmth. Flight feathers, found on the wings and tail, provide loft. Male birds also often use their feathers to attract mates.
Wings
Wings are a primary characteristic of birds, but they are found on other types of animals too. For example, bats are flying mammals with wings, and many types of insects have wings. Strong muscles in the chest help to propel wings, allowing for flight. Bird bodies are curved specifically to give lift to the wings. Different wing shapes provide different advantages, depending on species. For example, wings that have sharp, narrow tips allow for greater speed. Wings that are longer than they are wide make it easier for birds to soar for extended periods of time. Elliptical, evenly shaped wings, which are most notably found on songbirds, allow for small, quick movement. Different types of birds are capable of swimming, like penguins and puffins, having wings that are shaped like flippers.
Beaks
All bird species have beaks, or bills – bony concentrations that are surrounded by layers of keratin. The shape of a bird’s beak provides strong clues about its dietary habits. Although some species of birds have tumia, sharp ridges along the edges of their beaks, none possess true teeth. Therefore, the beak plays a crucial role in feeding. Birds that primarily subsist off of seeds, for example, tend to have strong, cone-shaped beaks. Ducks, geese and other types of waterfowl have broad, flat beaks that are designed to help them strain food from water. Meat-eating birds like owls and hawks have sharp, hooked beaks that they use to grind, tear and rip their prey to shreds.
Eggs
Egg laying is another characteristic that is common to all birds, or members of the Aves class. However, it is not unique to this class of animals, as reptiles, fish, amphibians and insects also all lay eggs. Birds’ eggs have hard shells that are mostly made out of calcium; a layer of hardened mucus helps to keep them intact. Within an egg, the embryo gets its nutrition from the yolk and the egg white, which is known as albumin. The vast majority of bird species build nests for their eggs and proceed to care for the hatchlings until they are capable of fending for themselves. In most species, both males and females play important roles in caring for the young.
Nearly all species of birds incubate their eggs. Exceptions include megapodes, or mound builders, which rely on external heat sources like decaying vegetation, and brood parasites. The latter, including cuckoos and cowbirds, prefer to lay their eggs in other birds’ nests. Some birds, like murres and certain penguin species, don’t use nests at all, choosing instead to rest eggs on the tops of their feet during incubation. Incubation periods range from 11 to 80 days depending on species.
A set of eggs that is laid at one time is called a clutch. Anywhere from one to 20 eggs or so may be found in a single clutch. Some birds engage in determinate laying, meaning that they lay the same number of eggs per clutch every time. Most birds engage in indeterminate laying, meaning that the number per clutch varies.
There are many different types of birds eggs’ sizes and colorations. Linnet’s lay light blue eggs with dark streaking and spots.

Skeleton
Flightless species of birds have heavy bones that are filled with marrow. Birds that are capable of flight – in other words, most birds – have lightweight skeletons made up of hollow bones. Their skeletons have many fused bones, including collarbones, which help them to brace their wings effectively during flight. Birds have large breastbones, or sternums, that provide sturdy points of attachment for muscles of the wings.
Notable Types of Birds
Today, there are more than 10,400 extant different types of bird species in the world. Across North America and South America, there are more than 4,400 species of the Aves class.

Evolution of Different Types of Birds
The evolution of birds has been a topic of much debate for many centuries. Today, the most commonly accepted theory, the theropod ancestor hypothesis, posits that birds evolved from theropod dinosaurs during the Jurassic period, which happened between 165 million and 150 million years ago.
Theropod dinosaurs were two-legged dinosaurs, and the T. Rex is included among their ranks.
The earliest known bird on the fossil record, archaeopteryx, was a hybrid between a bird and a dinosaur. It had feathered wings like a bird but also had sharp teeth and a long, bony tail like a dinosaur. This and other types of early birds diversified rapidly throughout the Jurassic and Cretaceous periods. They quickly became capable fliers and exhibited extremely rapid growth rapids.
However, their populations were decimated by the major extinction event that eliminated dinosaurs entirely. After that point, modern birds diversified at an explosive rate, and there are now more than 10,000 different species all across the world.

FAQs (Frequently Asked Questions)
What are the four types of birds?
There are far more than only four types, or categories, of birds in the world. If “type” refers to “species,” then the figure is closer to around 10,400. Birds can be classified into different categories in a number of ways, including flightless birds versus birds that are capable of flight and birds that live mostly on land or near water.
How are birds identified?
Birdwatching, a popular pastime, involves identifying birds in the wild. Four things are looked to when identifying birds: their size and shape, their behavior, their habitat and their color patterns. By learning the basics of each of these categories, birdwatchers can identify birds in the wild more quickly – an important aspect of the sport.
Why do birds bathe?
Bathing is a vital part of feather maintenance. Water helps to loosen up dirt and other debris that has worked its way into the feathers. Once freed of dirt, the feathers are easier to preen. During preening, birds rearrange their feathers and dispense oil from the preen gland, ensuring that their feathers remain waterproof. This also traps an insulating layer of air beneath, helping to keep the bird warm.
Which birds cannot fly?
Some of the best-known examples of flightless birds include penguins, ostriches, emus, cassowaries and kiwis.
