The moving speed of bird creatures is the fastest among all creatures on earth, and the appearance characteristics of different birds are different. Some birds look very strange, and some birds have very strange hair on their heads. In the eastern part of the United States, there is a bird with blue hair on its head, the name of this creature is the blue jay.

Blue jay, a beautiful songbird, has a body length of 22-30 cm, a weight of 70-100 grams, and a wingspan of 34-43 cm. It has a grey-blue crest on top of its head, a white and grey neck, chest and belly, and black and white striped wings and tail. Its beak, feet and feet are black. At the same time there is a circle of black feathers on the neck.

Blue Jays live in forests, parks and gardens. Blue jays usually live alone or in pairs, gathering in small flocks during the breeding season and during migration. The blue jay doesn't fly very fast, and the usual speed is about 32-40 km/h. Blue Jays are noisy and active birds in winter and spring, but they are quiet and secretive during the breeding season. Their high-pitched chirping can often be heard in much of the United States in the spring.

Blue Jays like to eat some fruits and seeds of plants, and of course they are very fond of some small insects, and sometimes they will rob the eggs and small birds in the nest. But in the vast sky, blue jays also face the capture of predators such as eagles. While catching food, blue jays also need to avoid those natural enemies from chasing them, so blue jays fly at a very low altitude in daily life, so that they can avoid the pursuit of eagles with a high probability, and it is also convenient for them to find food.

Blue Jays are innovative creatures, and other creatures are often at a loss when faced with the constant occupation of their own habitat, and are eventually forced to die by the environment. But blue jays can change their habitat as the environment changes. If its own habitat is destroyed, the blue jay will choose another habitat, which also makes the blue jay's vitality more powerful.

Blue Jays are not only beautiful, but also very intelligent. The blue jay knows the correct way to escape the pursuit of its natural enemies. Besides, the blue jay will not lose its life due to changes in the environment. It is an innovative creature.
