Ravens Use Hand Gestures to Communicate: Scientific American   3WEHaV3RpEaUFDAoOBjCFzl72eJkfbmt4t8yenImKBUQF1ynBdGblrT wPcv2AQe

Ravens use their beaks and wings much like humans rely on our hands to make gestures, such as for pointing to an object, scientists now find.

This is the first time researchers have seen gestures used in this way in the wild by animals other than primates.

 

From the age of 9 to 12 months, human infants often use gestures to direct the attention of adults to objects, or to hold up items so that others can take them. These gestures, produced before children speak their first words, are seen as milestones in the development of human speech.
