巨嘴鸟主要生活在拉丁美洲的热带丛林地区,特别是亚马孙河一带。巨嘴鸟有一张长17～24厘米、宽5～9厘米、几乎与身体等长的大嘴。科学家发现,巨嘴鸟的大嘴有一个特殊用途:在热天或高温环境下可帮助巨嘴鸟降温。巨嘴鸟的嘴尽管很大,但喙里的骨头呈海绵状,所以重量很轻,边缘呈锯齿状,嘴上有鲜艳的色彩。 Toucan lives mainly in the tropical jungle region of Latin America, especially the Amazon River. Toucan has a length of 17 to 24 cm, 5 to 9 cm wide, almost as long as the mouth with the body. Scientists have found that the big mouth of the Toucan has a special purpose: to help the Toucans cool in hot days or at high temperatures. Although the mouth of the Toucan is very large, the bones in the beak are spongy, so the weight is light, the edges are jagged, and the mouth is brightly colored.
