Asunto: Eighty percent of urban fledgling catbirds killed by predators

 

Posted on 17 May 2012 Science Spotlight 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.
