20201022 Lauwersmeer国家公园上空的椋鸟群 必应壁纸

Lauwersmeer国家公园 Lauwersmeer国家公园上空的椋鸟群 春季和夏季的筑巢和繁殖季节过去后，Lauwersmeer国家公园上空的椋鸟成为高度群居的鸟类，通常聚集成千上千的鸟群。这些鸟群有时以低语的形式出现，当鸟群组成一个大而密的群体时，它们看起来像是一个单独的有机体一起运动，即使这些运动看起来是任意的。尽管科学家们还不太清楚在杂音中的单个椋鸟是如何协调它们紧密的流体结构的，但这种行为被认为是一种混淆的方式捕食者。想象一下如果你是一只猎鹰在狩猎，你看到一小群椋鸟，如果你抓住一只，这是一顿简单的食物。但是，如果椋鸟先发现了掠食者，它们可能会形成一种低语，俯冲和俯冲为一体，这使得猎鹰很难孤立和猎杀单个的椋鸟。

英语原文:

After the nesting and breeding seasons of spring and summer have passed, starlings become highly social birds, often gathering in flocks that number in the thousands. These flocks sometimes take the form of a murmuration—when the birds form a group large and dense enough that they appear to move together as a single organism, even if the movements seem arbitrary. Though scientists still don't quite understand how the individual starlings in a murmuration coordinate their tight, fluid formations, the behavior is thought to be a way to confuse predators.Imagine if you're a falcon on the hunt and you see a small group of starlings—an easy meal if you catch one. But if the starlings spot the predator first, they may form a murmuration, swooping and diving as one, making it difficult for the falcon to isolate and hunt an individual starling.
