Birds are more in numbers than living species. They all have unique identification like feathers and wings. Most avifauna have size feathers, that distinguish them from other animals. avifauna have four-chambered hearts, hard shell eggs, and keen vision. Every bird collects a lot of information about the environment through their eyes. Any animal or human being will come aside they know at the high to sense the smell of others. Some avifauna stretch their feathers with one side wings and their legs are wide. Another type of bird shakes its whole body stretching upward. Some avifauna will bathe in water or in depending on their comfort.
Bird’s characteristics
Most of the birds do their activity depending on the climate conditions, they will migrate from one country to another. Due to the climatic change, they will fly and stay for their convenience. Their presence of food is the main thing for all avifauna. Food and water will be major problems for their migration. avifauna have down feathers that provide insulation and two types of flight feathers found on the wings: thrust-producing primary feathers at the tip of the wing and lift-providing secondary feathers closer to the body. Contour feathers found on the body create a smooth, aerodynamic surface. The chest muscles of birds are highly developed as they are responsible for the flapping of the entire wing.
The two clavicles of avifauna are fused, forming the furcula or wishbone, which is both flexible and strong enough to support the shoulder girdle during flapping. In order to keep body weight low, avifauna have pneumatic bones, no urinary bladders, and usually only one ovary. Avifauna has developed an efficient respiratory system using air sacs unidirectional airflow and a cross-current exchange system with the blood.
Bird’s Feathers and wings
Different birds have various kinds of characteristics and similarities. According to their character, feathers are the most important part of avifauna. They use the feathers for flying and maintaining body temperature. All birds have different colors of feathers, shapes, and functions. All birds have wings and shoulder, elbow, and wrist joints so they can fly longer. Some avifauna can fly higher but most of them can’t fly too high due to the temperature. Another important structure of avifauna is the beaks and bills. Beaks help to gather in flowers, they are thin and small in size. Bills are for cracking and breaking down foods.
Whether they’re opening for takeoff, spreading wide for a lazy soar, or flapping to brake for landing, bird wings make flying look almost effortless. The Wright Brothers studied bird flight before they designed the first airplane. Now modern aircraft fly higher and faster than any bird, yet no manufactured device matches the graceful movements and mechanics of wings. It’s easy to marvel at the magic of a bird in flight, but understanding how it all works makes the process even more incredible. Here, we’ll explain how a typical bird wing functions, as well as explore the different types of bird wings and flight feathers you might spot on the visitors at your feeders and in your trees.
Hatching/laying
Birds make different kinds of sounds for mating. Most of them will find their pair correctly. At the time of mating, they need a calm environment. Early morning or evening is the right time for mating. Female birds will search for the best trees and places for laying eggs. They choose and make a suitable nest for hatching, and protection of eggs and their pets. After making their nest and feeling safe then only do they lay eggs.
Most genera lay an egg one or two days after fertilization. However, for some bird genera, it can take longer than that to lay eggs after copulation. For example, for Bald Eagles, like our own Jackie and Shadow, it may take 5-10 days. Lovebirds can lay eggs anywhere from 5 to 12 days afterward.
The Breeding in Birds
In the breeding, stage birds will make their nest clean and neat for their chicks. Various types of nests they will make such as cups, plates, scrapes, mud, or burrows with different shapes and colors to protect their chicks. Larger birds make mostly open-type nests. Some birds are capable of speaking like parrots. We can teach or train them, and they will respond to human beings.
Conclusion
Birds are flying worldwide. Different types of birds with various characters and also vary their shape and size. Like humans, birds also have the same factors and same gender. They have some features like feathers to fly, hooks to eat or eyes to see their vision, etc, As technology improved, more factories started causing pollution that affected fauna.
