The Yellow-olive Flatbill or Yellow-olive Flycatcher (Tolmomyias sulphurescens) is a species of bird in the Tyrannidae family.
Distribution / Range
It is found in tropical and subtopical forest and woodland in Central and South America, but over its range there are significant variations in plumage, iris-colour and voice, leading to speculations that more than one species is involved.
Its plumage is overall greenish-yellow, the lores are whitish, the crown is often greyish and some subspecies have a dusky patch on the auriculars.
The flat bill is black above and pale pinkish or greyish below; similar to the Yellow-margined Flatbill, but unlike the Grey-crowned Flatbill.
