  • 湿地•视频︱拯救神奇候鸟我们有时间

    Posted by EAAFP communications on November 23, 2016

    选择其他语言: 保尔森基金会 科学家们至今仍未完全了解水鸟迁徙的奥秘。   斑尾塍鹬从阿拉斯加一路南下飞往新西兰,中间不曾停歇。 如果候鸟遇上顺风,它们的时速有时最快可达60英里! 鸟类为什么要迁徙,又如何迁徙?鸟类在长途飞行中如何找到自己的迁徙路线?它们为何要成群结队地迁徙?它们又如何知道什么时候应该出发去繁殖下一代或是前往过冬地? 科学家尚不能完全确定鸟类如何找到迁徙路线。但是,我们可以从美国国家地理学会的解释中窥见一斑。 “候鸟体内似乎有一个全球定位系统(GPS),这个系统帮助它们每年沿着同样的路线迁飞。幼鸟可能借助太阳和星星的方位来定向,而一些研究人员则认为鸟类也能辨认出地标。 鸟类身上的某些器官也使得它们有出色的定位能力。鸟的眼睛与名为“神经簇N”的大脑区域互动,而该区域也许可以帮助鸟类辨别北方。鸟类内耳细胞中的铁微粒也可帮助鸟类辨识方向。 最令人感到惊奇的是,鸟喙也为鸟类的定位做出了贡献。它能帮助鸟类准确定位自身所处的位置。一些研究人员认为,鸟类可以在迁徙过程中嗅出自己的路线。这种“嗅觉地图”可以帮助鸟类确定地势与地形。联结喙与脑的三叉神经则帮助鸟类估算自己的准确位置。研究人员认为,三叉神经能帮助鸟类评估地球磁场的强度,两极磁场较强,而赤道磁场较弱。 鸟类如何导航? 美国国家地理学会给出了以下解释: 眼:利用太阳和星辰的位置定位。眼与脑之间的化学反应、利用磁场导航的能力同时起作用,使得鸟类感知方向,判断哪个方位是北方。 喙:鸟类可以运用“嗅觉地图“来闻出它们周围的路线,鸟类的嘴部神经有助于它们确定由地球磁场和地球本身导致形成的飞行角度,这就有助于鸟类调整飞行方向,前往某一特定特点。 耳:鸟类内耳中的铁微粒帮助它们通过地球磁场辨识方向。   原文: http://www.paulsoninstitute.org.cn/index.php/paulson-blog/2016/11/02/video-the-miracle-of-migratory-shore-birds/
