Uncommon and unobtrusive in lowland and foothill forests. Unremarkable yet distinctive in its appearance: olive brown above and pale below with a bicolored bill, somewhat resembling a large-bodied, small-headed sparrow in structure if not in size. Male has yellow edges on the wings and a blood-red eye; female lacks these yellow areas and has a duller brownish eye. Gives a nasal “nyeh!” as well as an odd, low grating trill. Forages at beehives, consuming beeswax like its more well-known relatives.
