NOTES: If not Buteo platypterus, but not quite right (??). Unseen bird was about 500 meters north of sede (refuge headquarters) on trail through primary, terra firme forest; though apparently only 50 meters away and up in the open about _ up large tree, I was never able to see it; bird called, but did not approach in response to tape playback; just as it was getting light; _ moon up; first few calls overloaded; compared with calls of Buteo brachyurus (LNS #28527 from Ecuador and LNS #23779 from PN Itatiaia) this call was similar to both, but not quite the same.
