“how ravens say “please come here”
the corvids—jays, crows and ravens—make tools, cooperate and hide food from potential thieves. now researchers in the austrian alps have observed ravens gesturing. in male-female pairs, one bird picked up a stick or bit of moss and pointed or waggled it. the other then approached. It’s a first for non-apes, the biologists say, evidence that corvids “rival even primates in many social cognitive domains.”
