Birds are among some of the top vertebrate creatures on Earth. There are over 9000 species of birds, and they’re scattered across all of the planet from the poles all the way to the equator.

Ornithology studies birds and falls under the zoological branch of Zoology. The term “Ornithology” is originated from the 16th century Latin word ornithologia which means “bird research”.

Because of their ability of flying, bird species have been able to inhabit special ecological niches that allowed them to survive the extinction of their closest relatives , dinosaurs.

Let’s explore the amazing varieties of birds that belong to this class Aves!

The main characteristics of Birds

The class Aves also known as Birds is only one among the categories within the greater Kingdom Animalia. Birds share certain characteristics with the closely related class called reptiles. However, they also possess some characteristics that are exclusive to these amazing creatures. Let’s look at the most important characteristics.

• Vertebrates are birds that possess an inner skeleton which comprises a spine, limbs and a skull.
• Endothermic birds maintain a constant body temperature all independently, without relying on any external influences;
• Bipedal birds live in the same habitat as humans (i.e. they move using two limbs when they’re sitting on their feet);
• The upper legs of birds have evolved into specially designed structures, called wings that enable flying;
• Its body largest bird is in the shape of a spindle (to help make the flight more comfortable and effective);
• The bones of birds are hollow inside to decrease the overall weight of the body.
• The birds are armed with a beak, not teeth in their mouths;
• Its body has been covered in unique feathers. The legs alone are covered in scales.
• The birds’ hearts are equipped that has 4 chambers. In this allows oxygen-rich as well as oxygen-poor blood flow is properly divided which aids in maintaining the same temperature;
• Birds have a complicated nervous system as well as a developed brain. Birds are thought as highly instructable and smart.
• There are two sexes of birds, male and female;
• The process of fertilization in birds is internal. Because of fertilization, a closed egg, which is waterproof, is formed.
• The eggs grow outside of the body, normally with the help of both parents, or occasionally just one parent.

If we were to describe birds in a strict way then we can say that they are warm-blooded bipedal vertebrate species, having forelimbs that have evolved into wings with feathers. They also come with a beak , instead of mouth.
