The plate above by Karen Phillipps shows the 7 species of Prinochilus flowerpeckers found in Borneo including a pair of Yellow-rumped Flowerpeckers (middle right) . The Prionochilus flowerpeckers have thick strong bills suitable for chopping up ripe figs as their gape (mouth) is too small to swallow ripe figs whole.
Whilst there are many observations of Prionochilus spp. flowerpeckers eating figs there are very few of Dicaeum spp. flowerpeckers eating figs.
