This year's Zoofest is all about birds, by way of celebrating the 200th anniversary of the death of local ornithological hero Alexander Wilson. There are family-friendly demos on bird ecology and evolution, a chance to build your own nest (presumably not scaled to human size), a bird of prey show and other treats.
