Previously treated as conspecific with L. megaplaga, but differs in plumage details; recent genetic analysis indicates that the two are better treated as separate species. Furthermore, vocal and genetic differences have been employed to suggest that present species might be separated into two, Eurasian and North American, species#R#R#R. Two subspecies recognized.
