Whether it's a wave or a thumbs up, in the animal kingdom it's usually only humans that 成し遂げる wordless gestures to communicate.

But new 研究 from the?University of Tokyo 明らかにする／漏らすs that a clever 種類 of bird - the Japanese tit (Parus minor) - does it too.

Scientists have 設立する that it ぱたぱたするs its wings to tell its mate to enter the nest first ? a polite gesture as if to say 'after you'.?

The biologists 述べる this as a sophisticated 肉親，親類d form of '象徴的な gesture' that until now only 大主教s have been known to be 有能な of.?

The Japanese tit also?produces calls in a 明確な／細部 order to 伝える コンビナート／複合体 messages?to each other ? 火刑／賭けるing its （人命などを）奪う，主張する as one of nature's smartest birds.?

'For over 17 years, I have been engaged in the 熟考する／考慮する of these fascinating birds,'?said 熟考する／考慮する author Toshitaka Suzuki, associate professor at the University of Tokyo.?

'They not only use 明確な／細部 calls to 伝える particular meanings, but also 連合させる different calls into phrases using syntactic 支配するs.?

'These diverse vocalisations led me to 始める this 研究 into their 可能性のある use of physical gestures.

When carrying little morsels to 料金d their nestlings, the birds enter the nest one at a time.?

But the 研究員s noticed that when arriving 支援する to the nest, the birds would first find a perch nearby first and then one would ぱたぱたする their wings toward the other.?

By analysing 321 of these nest visitations, they saw the wing-ぱたぱたするing 陳列する，発揮する 誘発するd the mate who was 存在 ぱたぱたするd at to enter the nest box first, while?the one who ぱたぱたするd entered second.

によれば the team, the birds deliberately directed the ぱたぱたするing toward their mate ? not toward the nest 入り口 as if to 示す its どの辺に.

Interestingly, the gesture was 成し遂げるd more often by the 女性（の） birds, after which the male usually entered the nest box, 関わりなく which had arrived first.?

'In nest visitations where both parents approached the nest 同時に, 女性（の）s 成し遂げるd wing-ぱたぱたするing in 42 per cent of 事例／患者s, 反して males did so only in 6 per cent,'?Professor Suzuki told MailOnline.?

'We need その上の 熟考する／考慮するs to 診察する why 女性（の）s 成し遂げる wing-ぱたぱたするing more often than males.'?

From humans to chimps and now tits, these clever animals use wordless gestures

In humans, gestures ? such as pointing at things, doing a thumbs up or waving your 手渡す ? are an integral part of how we communicate.?

There is a hypothesis that walking on two 脚s 許すd humans to 持続する an upright posture, 解放する／自由なing up their 手渡すs for greater mobility, which in turn 与える／捧げるd to the 進化 of gestures.??

They were once thought to be used 排他的に by humans, but closer 観察s of 広大な／多数の／重要な apes, such as chimpanzees and bonobos, 明らかにする／漏らすd that they too move their 団体／死体s to communicate without making a sound.?

In more 最近の years, 熟考する／考慮するs on other animals, such as ravens and fish, have shown that they also use some simple gestures to point at 反対するs or show something of 利益／興味 - called deictic gesturing.

However, 象徴的な gestures, such as showing an open 手渡す to signal 'after you,' 要求する コンビナート／複合体 cognitive 技術s.?

研究員s have 設立する that the?Japanese tit (Parus minor) uses wing movements as a gesture to 伝える the message 'after you'.

This is a sophisticated form of?象徴的な gesture and has never before been seen in birds, （人命などを）奪う，主張するs 熟考する／考慮する author Toshitaka Suzuki.?

'A previous 熟考する／考慮する showed that ありふれた ravens 選ぶ up inedible 反対するs (e.g., a twig) to 陳列する，発揮する them to other ravens, 潜在的に 類似の to a "showing" gesture in humans,' he said.

'However, in the 事例／患者 of Japanese tits, wing ぱたぱたするing 行為 and nest 入ること／参加（者） order appear 潜在的に 関係のない.?

'In other words, tits are ca pable of using wing ぱたぱたするing as a 象徴的な signal, thus 雇うing a 象徴的な gesture to 伝える a 明確な／細部 meaning arbitrarily.'?
