These cuties are small birds with black,grey and white buff plummage. The colors and patterns are typically identical in males and females, but scientists report that there are bigger "bibs" are seen on male chickadees. But this information is really insignificant in classifying different genders in these birds. Bird-watchers have to rely on gender specific behaviour, and vocalizations.
