Like its name, the most prominent feature of the yellow-billed stork is its long and yellow bill. It also has a tall and white body, as well as black wings. /VCG Photo

The zoo also introduced 14 crowned hornbills. They have large helmets on their mouths. When they eat, they always perform complicated "acrobatics": first they throw the food in the air, use their mouth to catch it and then swallow it smugly. /VCG Photo

The American red stork is one of the most endangered and valuable birds in the world. They are gray and white when they are young and gradually turn red as they grow up. It is hailed as one of the reddest birds in the world. /VCG Photo
