這少見的一幕拍攝於美國密蘇裡州山谷公園的世界鳥類保護區裡。這只叫做Minerva貓頭鷹聽到相機頻繁的快門聲,心存疑惑,為了一探究竟,伸出頭往後做了個180度後仰。



貓頭鷹的眼睛裡,有一種管狀結構在支撐著,如此貓頭鷹的眼睛幾乎不能動彈。大自然為了彌補這一缺陷,賦予了貓頭鷹極端靈活的脖子,它能使貓頭鷹的頭轉動270度。

48歲的攝影師Lisa Kee意外地拍到了這一看起來有點疼的姿勢。她說這是第一次拍到貓頭鷹這樣轉頭。“Minerva聽到快門聲,很好奇,頭轉來轉去的,然後忽然一個後仰,把我都看糊塗了,只得查看下相機看看這樣的事是否真的發生過。我看過很多猛禽的各種轉頭,但看到這麼徹底反轉倒是第一次。這些照片也成了我多年的最愛。照片使我得到了好多贊美,但很多人不相信這是真的。很高興,那天我帶著照相機,能拍下如此不可思議的一幕。”

Very cute bird.
I like it.
學名 Strigiformes
Owls can rotate their heads and necks as much as 270 degrees (135 degrees in either direction). Owls have fourteen neck vertebrae as compared to 7 in humans which makes their necks more flexible. They also have adaptations to their circulatory systems, permitting rotation without cutting off blood to the brain: the foramina in their vertebrae through which the vertebral arteries pass are about 10 times the diameter of the artery, instead of about the same size as the artery as in humans; the vertebral arteries enter the cervical vertebrae higher than in other birds, giving the vessels some slack; and the carotid arteries unite in a very large anastomosis or junction, the largest of any bird's, preventing blood supply from being cut off while the neck is rotated. Other anastomoses between the carotid and vertebral arteries support this effect
