The Arboretum Visitor Center hosts a Building a Birdhouse class on Monday, March 30, 3-5 pm. In this program, Berle Clay demonstrates how to build a simple, rugged birdhouse (demonstration is not hands on). There will also be discussion on where birds like to nest, why some like to choose their own nests, and what we can do to entice them to use the nests we build for them.
