Song type 1 = SO-SOO-la; 2 = SO-SO-LA; 3 = SO-LAA.
a) 22 May 1974. 1615 hours. Weather: Fair. Recorded from camp, birds some distance in woods. Singing actively from my arrival ~ 3:30 PM. Several birds heard, mostly type 1 but near end, very faint, is a type 2. (Field notes indicate that five or six birds could be heard by car.) Quality: 3. Level: +2. 203 tape. LN. Nagra IV; Sennheiser 405; 36" parabola.
Note: At end this part is one phrase type 1 recorded incidentally, 8:40 AM, 23 May 1974, copied here from N-IV to N-4.2 as it has a short first figure; the original of this (and others heard faintly in background too) is at beginning of Cut 2 of Arremonops tocuyensis.
b) 1800 hours. Recorded inside woods (~200 m.) from camp mostly type 1 of various kinds but also type 2. Quality: 3. Level: 0. 3.75 ips. 203 tape.LN. Nagra SN; AKG; 24" parabola.
Birds would not respond to whistled imitation. also they appeared to stay always in same spot and it may be they were already settled in their intended roosting places. Note: After the short "blank" section the rerecording from N-4.2 to N-IV was filtered 400/2000 Hz due to loud insect noise; before that was filtered 400/2500 Hz due to wind noise in foliage.
@ dawn of 23 May, first Soisola song heard @ 6:20 AM (other birds singing by 6:00 AM but it's darker inside forest). However, song did not attain the profusion with which heard yesterday PM. But birds were singing @ 8:30 AM (see Cut 2 of Arremonops tocuyensis) and at 7:30 AM; heard in background of SN attempt to record A. tocuyensis; not saved.
c) 23 May 1974. ~2:05 PM. Ditto. Quality: 3. Level: 0. 203 tape. LN. Nagra SN; AKG; 24" parabola. Rerecorded N-4.2 to N-IV. Collected = male #[blank]. Filtered 400/2500 Hz in N-4.2 to N-IV recording. Three type 1 phrases heard: first two are same phrase repeated in the recording and is the phrase of the bird recorded (= collected?); third phrase is of different bird.
A couple birds started singing ~ 2:00 PM. When I got in to where I'd left the reflector I found they were not in a good position for recording, so after recording one phrase from each bird I started whistling. Apparently one ofo these birds (the first recorded) approached circuitously and silently, then some minutes later it sang twice only ~ 10 m. to my left. As I was in an awkward position to turn reflector without attracting attention of bird, I didn't try to record it in its close position; it shortly walked into view, stretched up and flapped its wings, then shook itself (~1 min. after its second near call) so I collected it, confident that with numerous singing birds in area I could attract another. This bird was collected shortly before 2:30 PM and I remained at same place until ~3:00, whistled same song as male collected. A bird answered quietly (a female) but didn't approach. I went to [illegible word or symbol] remained in camp area until after 4:00 P M and no other birds sang, whereas yesterday at this time app. as many as five birds were signing actively. Could most of these have been females singing in interaction with the male?
