英國(guó)《每日郵報(bào)》7月4日?qǐng)?bào)道，據(jù)一項(xiàng)研究發(fā)現(xiàn)，野生未馴養(yǎng)的鴿子能夠識(shí)別每個(gè)人的臉，而且不會(huì)因?yàn)閾Q了衣服就不認(rèn)得了。
雖然在實(shí)驗(yàn)室里受過(guò)訓(xùn)練的鴿子可以表現(xiàn)出超強(qiáng)的感知能力，但是這項(xiàng)新的研究是第一次針對(duì)未經(jīng)訓(xùn)練的野生鴿子。實(shí)驗(yàn)表明它們具有同樣的能力。
在巴黎市中心的一個(gè)公園里，兩名體型和膚色都相似的研究人員穿著不同顏色的實(shí)驗(yàn)室工作服去喂一群鴿子。
其中一名研究員完全不理會(huì)鴿子們過(guò)來(lái)吃食；而另一名研究院則懷著敵意將它們趕走。
接下來(lái)的第二階段實(shí)驗(yàn)則是兩名研究人員都不驅(qū)趕這群鴿子。
這項(xiàng)研究重復(fù)了幾次，鴿子們始終能夠認(rèn)出那個(gè)趕他們走的研究人員，并避開(kāi)他，盡管他后來(lái)不再如此驅(qū)趕鴿子。
在實(shí)驗(yàn)期間交換實(shí)驗(yàn)室工作服也沒(méi)有使這些鴿子混淆，它們?nèi)匀粫?huì)避開(kāi)那個(gè)最初不太友好的實(shí)驗(yàn)人員。
法國(guó)巴黎西部南戴爾拉德芳斯大學(xué)從事此項(xiàng)研究的研究員達(dá)莉拉•博韋說(shuō)：“很可能這些鴿子能夠認(rèn)出研究人員的臉。”
博韋補(bǔ)充說(shuō)：“這種識(shí)別能力可能是由于鴿子從早期馴養(yǎng)到多年城市生活中與長(zhǎng)期與人打交道的結(jié)果�！�
Feral, untrained pigeons can recognize individuals and are not fooled by a change of clothes, according to a study.
Although pigeons have shown remarkable feats of perception when given training in the lab, the new study is the first research showing similar abilities in untrained feral pigeons.
In a park in Paris city centre, pigeons were fed by two researchers, of similar build and skin color, wearing different colored lab coats.
One individual simply ignored the pigeons, allowing them to feed while the other was hostile, and chased them away.
This was followed by a second session when neither chased away the pigeons.
The experiment, which was repeated several times, showed that pigeons were able to recognize the individuals and continued to avoid the researcher who had chased them away even when they no longer did so.
Swapping lab coats during the experiments did not confuse the pigeons and they continued to shun the researcher who had been initially hostile.
Dr Dalila Bovet， a co-author of the study from the University of Paris Ouest Nanterre La Défense, said: “It is very likely that the pigeons recognized the researchers by their faces."
Dr Bovet added: “This specialized ability may have come about over the long period of association with humans, from early domestication to many years of living in cities.”
