A comparison of plumage characteristics between
grey-sided flowerpeckers (
Dicaeum celebicum) from mainland
Sulawesi (top) and
Wakatobi flowerpeckers (
Dicaeum kuehni) from the
Wakatobi archipelago (bottom); male flowerpeckers are on the left and females on the right. The Wakatobi flowerpecker was long considered a subspecies of the grey-sided flowerpecker, but it was reclassified in 2014.
