"A well-marked species easily distinguished from C. cyanipectus, its 

 nearest ally, by the heavy markings on crown and nape, by its black bill 

 and by the entirely different color of its under surface. Like the former 

 species, it is strictly confined to the banks of fresh-water streams and it 

 is usually found in the woods." (Bourns and Worcester.)
