Take your birding knowledge to the “nest” level by learning to identify birds by nest! Join leaders for a walk that will highlight the differences in birds’ nests by cracking open various nest boxes. Discover how to find out who’s home and how to promote nesting in your own backyard. Meet in the lower lobby at the Horicon Marsh Education and Visitor Center, off of Hwy. 28 between Mayville and Horicon.
