在鸟类王国中,有些鸟与众不同,它们不像大多数鸟那样善于飞翔。在漫长的进化过程中,它们适应了在地面奔走,这些鸟中,最为人熟知的大型鸟有鸵鸟、鸸鹋、隆鸟和恐鸟等,我们今天来了解一下鸸鹋。鸸鹋又称澳洲鸵鸟,身高1.5~1.9米,体重约50~60千克,是仅次于鸵鸟的世界第二大鸟,只分布于澳洲大陆。它们跟鸵鸟外形相似,但雌、雄鸟都呈棕色,羽毛蓬松,这是因为它们的羽毛缺乏羽钩而构不成羽片。鸸鹋的腿 Among the bird kingdoms, some are distinctive and not as flying as most other birds. In the long evolutionary process, they are adapted to run on the ground. The most familiar birds of the family are the ostrich, the razor clam, the mandarin and the malaria. We will learn about the malaria today. Emu, also known as the Australian ostrich, 1.5 to 1.9 meters tall and weighing about 50 to 60 kilograms, is second only to the world’s second largest ostrich bird, only in mainland Australia. They are similar in appearance to ostriches, but females and males are brown and feathery fluff because their feathers lack plume and are not plume.鸸 鹋 legs
