Pallas's Leaf Warbler is a common passerine bird in China's coastal areas. Every spring, they are one of the earliest migratory birds. They can be seen in parks, green spaces, and communities. However, most citizens do not know them or even notice their existence. Therefore, people are not aware of the significance of protecting them. This is the dilemma faced by the protection of passerine birds in China. The purpose of my work is to let people know about the beautiful small birds that can be seen outside the house, and to realize the importance of protecting them and their habitat.
