NOTES: Neotropical Institute Cut #E-2. Bulk reel #500
203 tape.
Song type 1 = SO-SOO-la; 2 = SO-SO-LA; 3 = SO-LAA.
a) 6:30 AM. Bird with ~ low-pitched type 1 phrase. Notes all on one pitch. Quality: 1- to 1. Level: +3. 3.75 & 7.5 ips.
In background at one place is heard a type 2 phrase by another bird. Then a higher-pitched type 1 phrase also heard.
b) 7:00 AM. As this [higher-pitched] bird was gradually moving [along? down?], I switched the "focus" to it but after I finally "found" it, it gave only one more call which is here recorded; the bird of a) is heard "out of focus." Quality: 2+. Level: +3. 3.75 ips.
then more recording of same bird in a). The (or a) higher-voiced bird heard in background. Quality: 1-. Level: +3.
Cut E-2 was recorded down the path on the other side of the river from where I was camped, and from where the bird of Cut E-1 (especially b & d) was recorded and collected.
The bird of a) was brought (and kept) close by my whistling type 2 phrase, which seemed just as effective as type 1 in attracting the bird. This bird seen; male acc. to plumage, with very little black barring on back.
During the time when I was trying to find a good focus for othe higher-voiced bird, which was moving and apparently coming closer, the bird of a) began moving away from me in the direction toward the higher-voiced bird. Perhaps this was why the higher-voiced bird then "stopped" singing and apparently moved farther away. (I cannot be sure the high voice later heard in distance is by the same bird that had been close.) I tried imitations of all kinds (1 & 2, low & high) but the high-voiced bird did not come close again. However, the low-voiced bird again came close but it remain[ed] only briefly and started moving away.
I then changed my position to ~ 40 m. away, hoping this would bring the bird close again, but it continued moving away. However, I saw here another bird, female to judge from the plumage, which was foraging throughout the area. It remained in sight for a long time, at one point moving fairly close to me, all the time foraging. (Could this indicate that the apparent female had been giving the high-voiced song? See above.) ["Above" notes, referred to by recordist, are illegible due to apparent overexposure of that portion of the film.] This bird never once sang (and during this time I didn't hear the high-voiced song) and although I whistled all kinds of phrases, this bird appeared to pay no attention; gradually it eventually moved away out of sight and contact.
