春天是结账的时候(Spring is the time for billing)

这对深情的大西洋海雀知道一两件关于接吻的恢复性快乐的事，我们今天在国际接吻日庆祝。这个节日起源于英国，大约20年前在全球范围内流行，每年都提醒人们，接吻不仅仅是为了问候或社交礼仪。海雀有一种可爱的社交行为，在这里被称为billing。在这种行为中，它们把头左右摆动，嬉戏地拍打对方的喙。

This affectionate pair of Atlantic puffins know a thing or two about the restorative pleasures of kissing, which we are celebrating today on International Kissing Day. Started in the United Kingdom, the holiday went global about 20 years ago as a yearly reminder that kissing isn’t reserved just for greetings or social formalities. Puffins engage in an endearing form of social behaviour seen here called billing, in which they playfully tap each other’s beaks by swinging their heads from side to side.
