Have you ever noticed geese flying south in their V-shaped flocked only during one particular time of the year? In summer, the birds fly to their breeding homes and in winter, they fly to their non-breeding habitats. There are hundreds and thousands of species that fly around for migration. Most importantly, they can kilometers after kilometers for raising their little birdies or feeding them. This is how migration in the avian universe works. But, what if, the weather is unfavorable? Then they can fly to somewhere with the best ecological condition.
Now, many people develop the interest of bird watching but they not well-versed with the concept. Why do the birds migrate? How do they navigate? Or, are these birds in danger? The long list of questions is flocking around. Moreover, China is an excellent place to witness the migration. It sure is a lifetime experience for the novice bird watchers. So, if you are about to undertake the adventure of bird watching in China, you must know these things about migration.
What is the Purpose of Migration?
Birds start to move from one place to another for seeking safe breeding, warmth, and food. This mean, they tend to go to the areas with low resources to high resources. When they have sorted out their nesting locations and feeding items, they feel safe. Grey Parrot or Snowy Owl may migrate to the areas where the insect population is likely to be high. Usually, when winter approaches, there is a lack of insect availability. If the birds unlock a way of adequate food supply, they can thrive in the freezing temperatures of Xinjiang and various alpine ranges.
What are the Different Sorts of Migration?
The type is heavily dependent on the distance traveled. The long-distance migration is followed for the reason of finding food. Apart from the basic need, the birds consider geography, day length, weather, and other factors. No matter how arduous the journey is, there are hundreds of birds flying for migration. Besides the long-distance migration, the medium distance migrants only move from one state to another. Or, several states may be counted sometimes. Again, short-distance is seen among the birds that transfer to lower or higher elevations around the mountains. Sultan tit is a popular example of this type. In the end, there are permanent residents that never migrate. They have sufficient food supply throughout the year in one place.
Little Facts to Remember
Every bird species has a different time to migrate. The birds can cross a long distance while following the traditional migratory routes. These routes are predictable at times because they do not follow the regular landforms. They have a tendency to eat more before taking off due to the habit of storing high-energy fat. Also, the birds move at night in small groups for avoiding predators. There are other things to know,
Birds like geese and ducks fly in V-formation for decreasing wing friction. This shape is linked to efficiency and communication.
Some of the songbirds can travel at 500-2000 feet. The high altitudes help them conserve energy.
Migration is often dangerous for the birds because many of them fail to return home again.
Risk of Migration in China
The recent studies show that the migratory birds of Qinghai or Xinjiang are at risk. One of the current reasons is the high voltage power line. Due to the power discharge from the nearby transmission towers, the migration leads to death. Generally, human activities are to be blamed for the risk. When they are flying long distance, there are different aspects (such as legislation, environmental politics, and conservation measures) get in the way.
