The Smithsonian Migratory Bird Center is dedicated to understanding, conserving and championing the grand phenomenon of bird migration. Founded in 1991, we are located at the Smithsonian's National Zoological Park in Washington, D.C. → Join our Center
The National Wildlife Federation featured our Carolina chickadee study in a recent article. Chickadees feed their nestlings copious numbers of insects. But does the abundance of non-native plants in suburban backyards affect their ability to raise young?
Chickadees, and most other songbirds, prefer to feed their young caterpillars, and caterpillars are much more common on native plants.
Unfortunately, according to Doug Tallamy, entomologist at the University of Delaware and co-advisor on this study, "about 80% of suburbia is landscaped with plants from Asia."
