Highly intelligent, extremely social, sometimes maligned, and frequently misunderstood, the American Crow (Corvus brachyrhynchos) is also one of the most common and widespread birds of North America. Studies have documented some startling similarities to human social behavior, including mutual grooming (called "allopreening"), as demonstrated by the adult and hatching year bird on the cover. Crows have been hard hit by the West Nile virus; ongoing studies, including many utilizing Christmas Bird Count data, help to document and understand the magnitude of the virus' impact.
"Just for Ducks" is a Mount Diablo Audubon Society (CA) project that involves installation of wood duck boxes on urban creeks in Walnut Creek, CA. The diamond pattern of scratches below the hole aid the ducklings in climbing out of the box to fledge.
