Sonic booms created by Israeli warplanes speeding across the sky are having the unintended consequence of launching hibernating crocodiles into mating mode, the daily Maariv reported last week.

According to the newspaper, each time warplanes break the sound barrier over a crocodile breeding farm in the Golan Heights, the randy reptiles begin emitting their ritual mating cry.

“The powerful squealing noises, reminiscent of the sound of a car braking, can be heard from hundreds of meters around,” David Golan, head of crocodile breeding at the Hamat Gader park, told Maariv.

The calls appeared to be a response to the sonic booms, which seemed to convince the crocodiles that other males had begun making mating signals, the newspaper said.

There are around 100 crocodiles at the park, which is underneath airspace used by the Israeli air force for training runs.

A population boom is not expected, however, because the male crocs are all bark and no bite.

Despite issuing their signature mating calls when the planes break the sound barrier, there has been no uptick in actual breeding — and the “official” mating season does not begin until the summer.

以色列《晚禱報》(Maariv)上週報導,以色列軍機,超音速飛行產生的音爆,出乎意料使冬眠中鱷魚發情。

根據報導,每當軍機突破音障飛越戈蘭高地的鱷魚養殖場,蠢蠢欲動的爬行動物就開始發出他們儀式性的求偶叫聲。

哈馬特加代爾公園負責人大衛‧格蘭告訴《晚禱報》說,「強大尖銳叫聲,像汽車剎車的聲音,數百公尺遠都能聽見。」

《晚禱報》認為,鱷魚的叫聲回應,可能是因為把超音速飛行聲音誤認為其他雄性鱷魚的求偶信號。大約有一百隻鱷魚在哈馬特加代爾公園,該公園就在以色列空軍訓練領空下方。

這不致造成鱷魚大量繁殖,因為雄性鱷魚不會真的做什麼,它們只是叫叫罷了。

儘管鱷魚在飛機超音速飛行時發出求偶信號,實際繁殖量並未增加,況且「正式」的求偶季節要到夏天才開始。
