Tiny stump-tailed flycatcher; one of the smallest birds on earth. Minute size and compact body give it a unique appearance, in some ways looking more like a bumblebee than a bird. Whitish underparts with green back, gray head, and white spectacles. Found in mature and secondary rainforest, especially in areas with tall trees. Usually perches in the rainforest midstory and can be tricky to spot. Its song is a soft pair of short trilled notes “trrr-trrr,” sounding rather insectlike.
