Which is the best bird?
Cerulean warbler
Dark-eyed junco
Chestnut-backed tanager
Hispaniolan spindalis
Rosy thrush-tanager
Red-winged blackbird
Snow bunting

The Passeroidea superfamily is enormous, so this mid-level clade is included to help us narrow things down! The nine-primaried oscine group is named because these birds have only nine easily visible primary feathers visible on each wing.
