The Chinese crested tern is a type of seabird. The bird is about 30-40 cm long, with a black crown, gray wings and a white body. They live mainly on small fish. 1 According to a report, there are only about 150 Chinese crested terns all over the world.
The first record of the bird was in Indonesia in 1861. 2 Scientists once believed that this type of bird may die out. Amazingly, over 60 years later, some birdwatchers saw many Chinese crested terns in Fujian and Zhejiang.
Scientists working in a nature reserve in Zhejiang wanted those birds to stay there. They built some artificial nests(人工鸟巢). They even put some handmade birds of the same size as Chinese crested terns there. 3 More and more Chinese crested terns flew to the islands and laid their eggs.
Chinese crested terns lay eggs as the weather gets warmer, usually between April and August. 4 During their stay in Zhejiang, scientists and volunteers from a Chinese crested tern protection project do a lot of work. They record the information of every bird on the islands. They help them lay eggs safely. 5
