If you want to watch birds and learn something about them, you can find a good place near a bird’s nest to watch. But remember to keep a safe distance and not to disturb (打扰) them.
Birds are usually busy sitting on eggs and taking care of their babies from April to June. Baby birds are too young to leave the nest, so their parents often fly out to look for food and come back quickly. This is a great time to watch birds. When we watch birds, we’d better hide ourselves quietly. And it’s better to use binoculars to help.
Sometimes, birds’ nests are damaged or abandoned for different reasons like natural disasters or the death of parent birds. Then people can help to make a bird’s nest. But how to do that? A good bird’s nest must be very strong, thick and comfortable. If you want to make one, please follow these tips:
1. Make a small hole in the front of the nest as a “door”. The “door” should be big enough so the birds can fly in or out easily.
2. Choose the materials carefully. Make sure the rainwater can’t go into the nest.
3. Don’t forget to colour the nest. Choose colours like green and brown to help it hide in the natural environment.

As we all know, climate change has great influence on the birds' living environment. Take Poyang Lake as an example. As an important habitat for many seriously endangered birds, the water level of Poyang Lake has experienced unusual rises and falls in recent years.
"In some years, the lake experienced floods, while in others it experienced a
shortage of rain. Both of these situations led to less food in the birds' habitat," Qian Fawen, a researcher from the National Bird Banding Centre of China, said.
To solve such habitat problems, China has named 1,140 places in recent years as important living and wintering spots in wetlands. To protect the wetlands, a law was made in 2022 to control human activities. According to the law, people can't overuse the wetlands. What's more, they can't pour waste water into the wetlands.
As these methods work well, more birds are seen wintering in wetlands in China. In February 2023, Hunan Province reported that 72 kinds of waterbirds spent the past winter at Dongting Lake, and that the number of one endangered kind of bird increased from 300 in the 1980s to more than 5,000. All of these cases point to a better future.
