朱紅蜂鳥 朱紅蜂鳥靜立在枝頭 你知道在美國，9月的第一個(gè)星期六是國家蜂鳥節(jié)嗎?這是多么棒的一只鳥啊。朱紅蜂鳥，比如這張照片中的朱紅蜂鳥蜂鳥，對(duì)健康的生態(tài)系統(tǒng)至關(guān)重要。因?yàn)樗鼈儚拈_花植物中吸取花蜜，所以朱紅蜂鳥是比大黃蜂更好的授粉者。

它們的適應(yīng)性也很強(qiáng)。當(dāng)北美太平洋海岸的許多其他蜂鳥隨著秋冬季節(jié)的臨近而遷移到溫暖的地區(qū)時(shí)，朱紅蜂鳥可以通過增加脂肪儲(chǔ)備，或者在必要時(shí)減慢新陳代謝來應(yīng)對(duì)寒冷，從而在較冷的溫度下生存下來。

如果你不知道蜂鳥國歌的歌詞，很簡單:跟著哼唱就行了。

原文:

Did you know that in the US, the first Saturday in September is National Hummingbird Day? You do now! And what a terrific bird to celebrate. Hummingbirds, such as the Anna's hummingbird in this photo, are crucial to healthy ecosystems. Because they drink nectar from flowering plants, Anna's hummingbirds are even better pollinators than bumblebees.

They're also highly adaptable. While many other hummingbirds on the Pacific Coast of North America migrate to warmer areas as fall and winter approach, Anna's hummingbird can survive the cooler temps by bulking up its fat stores or, if necessary, slowing down its metabolism to cope with the cold.If you don't know the words to the hummingbird national anthem, it's easy: Just hum along.
