NOTES: Neotropical Institute Cut #E-5. Bulk reel #500
Song type 1 = SO-SOO-la; 2 = SO-SO-LA; 3 = SO-LAA.
Weather: Clear, fair. Bird with Type 3 phrase. Quality: 2, 1-2. Level: -3. 24" parabola. Quality: 2. Level: -3. No parabola. 175 tape.
Note that between the loud phrases are heard some softer phrases. One or more are by a distant bird but most are "quiet song" by this same bird (or a female with it?) and note that some of these are very like a type 1 phrase but continuously slurred (and *very similar to a corresponding case recorded in Rancho Grande - Turiamo: cf. Cut [blank].
*This last phrase with open mike is included again, as original copied in the field from SN recorder to N-IV (on 203 tape).
Copy from N-4.2 to N-IV on 175 tape.
Notes: Although this bird decoyed well when I was down in the gully, I could never see it for it always stayed hidden behind brush or trash. I then went up on plateau and decoyed bird up there, where I saw it briefly but it fled rapidly before I could collect it. I tried changing position but bird would not decoy to me again. It continued singing and went back into gully but much further up. I went near there but still could not decoy the bird, which then became silent.
After some minutes, it started to sing again, but this time the phrases were repeated ~ 2X as frequently as before. I again tried to decoy, without success. There was a small rise between the bird and me, so I walked carefully up the slope and when I looked down into the low beyond I saw a bird and immediately shot it. It turned out to be a female (#8802).
I did not see the bird collected sing (didn't wait for that) and so now it is uncertain whether the bird collected was the singing bird, or whether there were two birds present, male and female, and both sang, therefore the "cadence" was more rapid, or whether a male was singing and sang more rapidly because a female was then present. If another bird was present, which I didn't suspect when I shot, it quickly fled when I went immediately to retrieve the bird shot. (For evidence that this may have been two birds singing, see note #9 on general note sheets.)
