Pearly-breasted Conebill is rare and patchily distributed along large rivers in the Amazonian lowlands. They are primarily limited to middle-aged and old river islands, where they forage in the canopy of mature Cecropia trees. Adults are pale blue-gray overall, with their back slightly darker than their underparts. Compare the very similar Bicolored Conebill (Conirostrum bicolor), but note the less sharp contrast between the back and underparts on Pearly-breasted, and the lack of buff coloration on the underparts. Also, although Bicolored Conebill uses similar habitats as Pearly-breasted, the latter is more specialized to the canopy of tall Cecropia stands. Juveniles of both species are pale olive above and yellow below, and appear very similar. The song of Pearly-breasted Conebill is a high, jumbled series of squeaks and chatters that is faster and higher than that of Bicolored.
