When most people look at a forest, they see walking trails, deer yards, or firewood for next winter. But scientists at the Harvard Forest and the Smithsonian take note of changes imperceptible to the naked eye — the uptake and storage of carbon. What they’ve learned in a recent study is that an immense amount [...] [...more]

Scientists from the Smithsonian Migratory Bird Center have found that fledgling catbirds living in the suburbs are extremely vulnerable. Almost 80 percent are killed by predators before they reach adulthood. Nearly half of the deaths are connected to domestic cats. The team studied catbird nests in 3 suburban neighborhoods in Maryland: Spring Park, Opal Daniels Park, and Bethesda. Learn more about this 2011 study by clicking here.
