NOTES: Neotropical Institute Cut # 4. Bulk reel: 134
Weather: Cloudy, fair. *Birds not seen (although some taken in net in this same approximate spot) and identification is not 100% certain but seems possibly correct; also while walking to this spot I heard "song" coming from here that according to my memory then was similar to that of this species. Quality: 2. Level: +5.
"Burry" calls (these are rather long and down-slurred; also tend to be of two syllabies). Quality: 1-2. Level: +3.
