Birds vary in appearance. The northern long-tailed (Aegithalos caudatus) that I will introduce to you today can be described as a cute and growing bird in the bird world. They are petite, with small round eyes, short mouths, and round bodies, especially in winter, when their feathers turn into fluffy and fluffy, like a ball of hairmay make the line of sight clearer, and from time to time he will make a "tilt his head to kill" action, which looks very cute and cute. People often affectionately call it "little fat chirp", "flying rice balls" and so on.
The northern long-tailed is a small songbird of the long-tailed family of the family. It was once used as a subspecies of silver-throated long-tailed, and later separated into an independent species. The head and thorax are pure white, the back and tail are covered with black feathers, and the shoulder feathers are grape red. They mostly live in colder regions, and can often be seen in northern Europe to Siberia, northeast China and northern Xinjiang, and some individuals choose to winter in Beijing and Hebei. They often move in groups, and if they are alone, they will mix with other birds, and in winter, they will often stand in a row on the trees to "huddle for warmth" to reduce heat loss. It is often found in woodlands with rich shrublands, but also in urban parks. They often hang upside down on tree branches for food, mainly feed on insects, but also eat plant seeds, etc. It is a terrestrial wild animal protected by the "three haves" of the state with important ecological, scientific and social values.
