This is a fun family workshop to create a natural style birdhouse from a gourd to be a welcoming nesting space for birds in your own backyard. Birdhouses are increasingly important to cavity nesters like wrens and chickadees. This is a Partnership for Programming event sponsored by the Thorn Creek Audubon Society. All materials will be provided. This program will take place indoors in an accessible facility.
