Hitherto treated as conspecific with C. cela, from which it is deeply divergent genetically#R; further differs by (in race vitellinus) its richer yellow rump (1) and smaller yellow shoulder-patches (1) or (nominate race) smaller size (at least 1); and (both subspecies) absence of yellow on outer rectrices, so that yellow of rump is separated from black of tail in straight line (2); song that ends with a rather sharp-sounding note at fairly high but flat pitch vs song ending with lower-pitched and slurred last notes (2); and absence of second song type (which in C. cela consists of an extremely varied performance that can last for minutes and includes different loud whistles and screeches, many of which are clear mimicry of local birds and other sounds) (3)#R. Species name previously listed herein as "C. vitellinus", but name flavicrissus has priority. Two subspecies recognized.
