NOTES: Neotropical Institute Cut # 11. Bulk reel: 67; Extra cut length: 7:34; Extra cut length: 6:57; Extra cut(s) on bulk reel: 68; Extra cut length: 10:38; Extra cut length: 9:15In several places in the Rio Grande area, I was sure I had heard the "repeated hoot" song (= Type A) of this species. I tried playing the field tape on several occasions but without result.a) 9:00 PM. Birds brought in by playback. Quality: 2. Level: +10. 3.75 & 7.5 ips.Tonight, although I had not heard the birds before here at km 6, I decided to play the tape anyway and was rather surprised by the result. Note that the field tape was prepared from recordings made in the North Central region (Colonia Tovar) which corresponds to nigrolineata whereas the present birds are of nominate huhula (previously considered a separate species).In the initial reactions, both birds of the pair came overhead and Iquickly recorded this, parabola not "focused." The female has the higher voice and a typical female song; the presumed male has the lower voice and typical male song.I then changed to 7.5" and focused on the female. The male is not heard at first but then calls in background; he didn't stay overhead. Quality: 1. Level: +3.Then some time after playback; still focused on female. Male heard in background. Quality: 1-2. Level: +10.b) 10:20 PM. Now ~ one hour after playback. The female was the only one that maintained an active interest. Presumed male stayed in the distance.c) Due to a broken belt I changed recorders. Both birds are heard ~ equally in ~ typical "B-type" songs. No attempt made to keep in focus while repairing other recorder. Quality: 2.Then the female gives one hoot, then a "hoot series" (= type A song), then more isolated-hoots. Also heard is a "cry" as in Cut 10. Then female reverts to "type B" song. More "crys" [sic] are heard by what I think maky be a young bird.Ends ~ 10:50 PM. This continues as Cut 11d on Reel 5.d) 9 July 1966. Weather: Clear, no moon. The sounds from female and "young"(?) continued for some time but recording not saved. Resumed here again at ~ 11:00 PM. Quality: 2. Level: +10.The crys [sic] of the "young"(?) are heard constantly and occasional single hoots or modified type B songs by the female, also then a series of ~ normal type B songs. Then there are several long hoot series (= type A song) by the female. Then some isolated "hoots."Then there is another "type A" song by female. (Cries of "young"(?) continue all the time. Then after a silence, at ~ 11:15 PM the female gives a series of type B songs and the male (absent or silent during all this time) gives one song. Then after two-three minutes silence (not saved), calls by female that are between songs and hoots. Then after more silence (except foregoing?), a type A song, apparently by female.Ends ~ 11:20 PM.Note: At end and also after male song are calls of the "bleating frog."e) 11:30 PM. Continues from above after ~ 10' cut. Quality: 2. Level: +10.11:55 PM through 12:25 AM. Cries by "young"(?) and calls by female. Then continues with various cuts in the time. Long hoots (Ltype A) are heard from both adults.We hear calls, similar to cries of"young"(?), and it's obvious from the different pitch and timing that two different birds are involved. And there is then a sequence near end where the "calls" of the adult change to a type A song. This seems to confirm that the calls are of huhula and the "cries" are very likely of a "young" huhula.Ends ~ 12:45 AM. Continues on Reel 6 with Cut #12.
