Every year, the regular migrations and movements of the birds around us happen like clockwork. But every year, it’s not just the expected that happens, but also the unexpected. In this presentation, long-time local birder, regional eBird reviewer and Illinois Ornithological Records Committee head Geoff Williamson will take us on a tour of the rarities that have appeared in the greater Chicago area over the last four seasons. There were more than 30 of them, drawn from nearly two dozen species and representing about 20 different families of birds.
