Rare and reclusive long-billed inhabitant of moist montane and foothill forests at 1350-3000 meters. Dark brown and heavily patterned overall, with densest patterning on the back. Small pale patch present on upper belly. Forages in dense vegetation, flushing explosively if sufficiently startled. Can be quite tame, allowing close approach if located. Flies between and sings from display perches, giving a fast-paced series of “chu” notes. Also gives a high-pitched sneezing call, and a lower harsh note.
