Explore the amazing variety of bird nests with this multimedia presentation from Anne Swaim, Executive Director, Saw Mill River Audubon. From the massive nests of eagles to walnut-sized hummingbird nests, from cavity-nesters inside trees to ground-nesters to birds that weave intricately woven baskets that hang from branches, birds are master builders! Find out about how different birds develop from eggs to nestlings to fledglings and what to do if you find a nest or young birds in need of help.
