Types of Birds

Types of Birds: Birds are some of the most successful vertebrate animals on Earth. There are more than 9,000 bird species, and they are spread over the whole planet, from the poles to the equator.

Ornithology is the study of birds, and it comes under branches of Zoology. The word ‘Ornithology’ is derived from 16th-century Latin word ornithologia meaning “bird science“.

Due to their ability to fly, birds have managed to occupy unique ecological niches, which helped them survive the demise of their close relatives – dinosaurs.

Let us explore the astounding kinds of birds in the class Aves!

Main Characteristics of Birds

Emu (Birds are Bipedal)The Class Aves or Birds is just one of the classes of the bigger Kingdom Animalia. The birds share some characteristics with another closely related class – Reptiles, but they also have some features that are unique to these fantastic creatures. Let us go through their main traits.

  • Birds are vertebrates – they have an inner skeleton that contains a spine, limbs, and a skull;
  • Birds are endothermic – they maintain constant body temperature by themselves, without depending on outside factors;
  • Birds are bipedal (i.e., they move on two limbs when they are on the ground);
  • The upper limbs of birds have evolved into specialized structures – wings, that allow flight;
  • The body of the most bird is spindle-shaped (to make the flight more comfortable and more effective);
  • The birds’ bones are hollow inside, to lower the overall weight of the body;
  • colorful feathersThe birds have a beak instead of a mouth with teeth;
  • The body is covered with unique structures – feathers. Only legs are covered with scales;
  • The birds have a heart with 4 chambers – this way, the oxygen-rich and oxygen-poor blood is divided correctly, which helps with maintaining constant temperatures;
  • The birds have a complex nervous system and a well-developed brain. Many birds are known to be highly teachable and intelligent;
  • There are two sexes in birds: male and female;
  • Fertilization in birds is internal. As a result of fertilization, a closed-off, waterproof egg is formed.
  • The eggs develop outside the body, usually under the care of both parents or sometimes only one.

If we want to define birds strictly, we would say they are warm-blooded, bipedal vertebrate animals, with forelimbs evolved into wings, covered in feathers and with a beak instead of a mouth.

Types of Birds

Because of the constant flow of the new data obtained due to the progress with DNA sequencing, the classification of birds and relationships between orders and families is continually changing. The latest classification contains 40 orders of birds instead of 23 bird orders in the previous one.

  • Birds of Prey

    Diurnal Birds of Prey (Accipitriformes)

    The first type of birds is from the order Accipitriformes. It contains the diurnal birds of prey (i.e., active in the day time), such as hawks, eagles and ospreys. All these large birds have a sharp, hooked beak with visible nostrils.

    As per the latest taxonomic classification, both hummingbirds and swifts belong to the order Apodiformes. Most of the birds in this order are very tiny and have “underdeveloped” feet. About 10% of the bird species in this group are threatened or endangered.

  • Kiwis

    Kiwis & Extinct Birds (Apterygiformes)

    The next group of birds belongs to order Apterygiformes, which is composed of flightless birds that live on the ground, such as the famous Kiwi – the national bird of New Zealand. A unique feature of these monogamous kiwis is that they have a long, flexible beak with a downward curve on end. Most of the bird species in this order are extinct now.
