Male splendid fairy-wrens in Australia prefer to make their calls after a predator makes its, and females pay more attention when the calls are linked.
　　澳大利亞的雄性華麗細(xì)尾鷦鷯一般會(huì)在聽(tīng)到捕食者的警告叫聲后發(fā)出回應(yīng)叫聲，而雌性鷦鷯則對(duì)這種接連發(fā)出的回應(yīng)叫聲特別敏感。
　　It’s one of the oldest moves in teen dating. Head to a scary movie. As soon as the scarymusic kick in, your date cuddles closer for comfort. Well, some birds may have the same idea. Splendid fairy-wrens are small, sexually promiscuous birds native to Australia. It turns out that males get the attention of potential mates by making their move after apredator announces its presence. The research was published in the journal BehavioralEcology.
　　青年人約會(huì)時(shí)經(jīng)常去看恐怖電影，也會(huì)聽(tīng)那些令人驚悚的配音。當(dāng)毛骨悚然的音樂(lè)響起時(shí)，你的同伴可能就會(huì)靠得更近，以此尋求一些安全感……小鳥(niǎo)同樣用這樣的策略?！叭A麗細(xì)尾鷦鷯”是一種體型嬌小，經(jīng)常更換交配的產(chǎn)于澳大利亞的小鳥(niǎo)。最近的研究表明，這種鳥(niǎo)類(lèi)的雄鳥(niǎo)在捕食者發(fā)出警告聲音后，發(fā)起行動(dòng)以引起獲取雌鳥(niǎo)的關(guān)注。這一研究結(jié)果發(fā)表在了《行為生態(tài)學(xué)》雜志上。
　　[Bird sound] That’s the sound of butcherbirds, which prey on splendid wrens. Every time male wrens hear that cry, they sing this in response [wren sound]. Researchers say the calls become layered atop one another, almost like a duet.
　　咕咕咕，這是伯勞鳥(niǎo)的叫聲。伯勞鳥(niǎo)的獵物就是華麗細(xì)尾鷦鷯。當(dāng)雄性鷦鷯聽(tīng)到伯勞鳥(niǎo)的這種聲音，他們就會(huì)做出回應(yīng)，嘰嘰嘰。研究人員表示，鷦鷯的回應(yīng)聲緊跟伯勞鳥(niǎo)的警告聲，很像二重奏。
　　The scientists tested the response of female wrens by playing recorded bird calls. They played just the male fairy-wren call. Then they played the trill of the wrens singing　immediately after the butcherbirds. The females became significantly more alert―looking to the sound or singing in response―after hearing the two calls together than they did if they heard just the wren. And so for both teens and wrens, a bit of fear might help a guy get the chick.
　　研究人員利用錄音的方式，調(diào)查了雌鳥(niǎo)對(duì)此的反應(yīng)。研究人員首先只播放了雄鳥(niǎo)的普通叫聲，然后播放了伯勞鳥(niǎo)的警告聲及雄鳥(niǎo)立即做出的回應(yīng)聲。結(jié)果雌鳥(niǎo)在聽(tīng)到后者時(shí)，做出的回應(yīng)很強(qiáng)烈，會(huì)立即尋找叫聲的方向，并同樣發(fā)出回應(yīng)叫聲。所以，無(wú)論是青年鷦鷯還是青年人，利用一下恐懼，就會(huì)幫你捕獲芳心。
