关掉夜景灯,为了迁徙的鸟儿

[-]
鸟这种动物就像蛾子一样会被夜晚的灯光所吸引——然后分不清方向,他们会绕着发光的建筑物飞,有时候会一头撞上去,或者,精疲力竭的掉在地上。

科学家们无法解释这种行为,但是明尼阿波利斯的时钟博物馆的研究员以及明尼苏达州自然资源部正在倡导关闭灯光以保护夜间迁徙的鸟儿。

参与这个项目的包括房屋的所有者,承租人以及来自明尼阿波利斯、圣保罗、布卢明顿的32栋建筑物的物业公司,他们均承诺在春秋季鸟类迁徙的季节减弱建筑物(景观)灯的强度。类似的项目已经在多伦多、纽约、芝加哥进行。

时钟博物馆的鸟类学家Bob Zink认为,明尼苏达州的加入是非常重要的,因为它就沿着密西西比河,是鸟类迁徙的必经之路。此外,除了减少夜行性鸟类迁徙路线上的灯光障碍,研究人员也尝试测定为什么某些鸟儿比其他同类更多的穿梭于高楼大厦之间。

在明尼阿波利斯,每年有67%的鸟类死亡与该市的两栋摩天楼有关。(话说,是不是应该把这俩楼拆了啊?)

    部分迁徙的鸟类定位靠的就是星星,可惜城市里面灯光太强,不但导致天空的星星无法看到,更可恶的是——鸟儿把灯当星星了……

    原因是这样的:

    鸟儿在夜间通过星光和鸟儿脑袋方向的夹角来判断方向的。由于星光射到地球近似平行光,根据平行线的同位角定理,鸟儿维持相同的夹角就可以走一条直线。而地面的灯光光线是辐射状的,你可以在纸上画着验证一下,想要让一条线维持和这些辐射线相交时的夹角相同,它肯定是一个螺线。

    Thanks for the several tips provided on this weblog. I have realized that many insurance agencies offer clients generous reductions if they opt to insure more and more cars together. A significant amount of households include several cars or trucks these days, specially those with more aged teenage kids still residing at home, and also the savings with policies can easily soon increase. So it is good to look for a bargain.

    I have observed that car insurance firms know the automobiles which are susceptible to accidents as well as other risks. Additionally they know what kind of cars are given to higher risk and the higher risk they’ve already the higher a premium price. Understanding the straightforward basics associated with car insurance will let you choose the right types of insurance policy that will take care of your wants in case you get involved in any accident. Thanks for sharing the actual ideas with your blog.

    I’ll gear this review to 2 types of people: current Zune owners who are considering an upgrade, and people trying to decide between a Zune and an iPod. (There are other players worth considering out there, like the Sony Walkman X, but I hope this gives you enough info to make an informed decision of the Zune vs players other than the iPod line as well.)

    I have realized that online education is getting well-liked because accomplishing your degree online has become a popular alternative for many people. Numerous people have certainly not had a possible opportunity to attend a traditional college or university yet seek the elevated earning possibilities and career advancement that a Bachelors Degree gives you. Still other folks might have a diploma in one field but wish to pursue another thing they now possess an interest in.
