Did you know 95% of songbirds only feed their young caterpillars and larvae? The babies can only tolerate the soft bodies of these insects who can generally only survive on native plants. Listen to Douglas Tallamy , an American entomologist, ecologist and conservationist, and professor in the Department of Entomology and Wildlife Ecology at the University of Delaware, discuss how Native Gardens can save our birds.   He has written and co-authored several books as well as papers, including "Bringing Nature Home" and "Nature's Best Hope".
