Below: A freaky intergrade chickadee in western Washington Co., Maryland (6/4/2011). Note the messy bib, long tail, and white secondary edges that suggest Black-capped Chickadee, but the lack of white in the coverts and dirty white cheeks that are more supportive of Carolina. Its voice was intermediate in quality, tending more toward Black-capped.
