Burrito was a bit nervous going out on Young’s Hill today- most likely because before Friday, due to the Taylor Bridge Fire, the chimps hadn’t been out there in nearly three weeks. As soon as he got out there, he stood bipedally and his hair was pilo erect (standing on end), both signs that he was a bit worked up or aroused. But Foxie and Missy both reassured him that everything was safe.
who then hugged him back as a way to calm him down. If you look closely at the photo, you can see that Burrito is fear grimacing (aka- showing all of his teeth. This facial expression looks much like a human smile, but is usually a sign of fear or intense excitement).
Still a bit nervous, he approached Missy with a bent wrist. A bent wrist is a submissive gesture and often an effective way to gain reassurance from a more dominant individual. He has a large fear grimace in this photo.
