I gave a talk at the University of the Third Age and the Royal Zoological Society of Scotland 2014 Study Day held at the Edinburgh Zoo. It was a great audience and lots of fun! We gave the talks in the lovely lecture theater in the Budongo Trail Chimp exhibit. It was an amazing experience to hear the chimps vocalize and play during the talk. At one point during my presentation the chimps starting vocalizing (in response?) after I played chick-a-dee calls of black-capped and mountain chickadees! Ida Bailey and myself gave a talk entitled: From Art Critic to Structural Engineers: The Amazing Abilities of Birds. We focused on (1) how we can use categories to ask question about how birds perceive the world, (2) tool use, and (3) how birds learn to select appropriate nest building material.
