NOTES: Neotropical Institute Cut # 3. Bulk reel: 57 a) Natural song by pair. Quality: 1-2. Level: +10. "b" Cont. with focus on higher-voiced bird, which then flies. (This and following may be after playback.) Quality: 1. Level: +10. "c" - Cont. on pair, ~ = focus. Quality: 1. Level: +10. "d" Cont. with focs on "high-voiced" bird. This bird then collected and proved to a female (R.G. #4334). Quality: 1. Level: +5. e) This is the bird left after the high-voiced bird (female) was collected. Presumably it is therefore the male. From their actions, the birds seemed obviously to be a pair. First focus, 2 calls. Quality: 1. Level: +2. Second focus, 1 call. Quality: 1. Level: +2. Then with open mike two calls, each witih different background. Quality: 1. Level: +10. Note that the lower-voiced bird (app. the male) seems always to imitate the "duets.".
