    Equipment Note

NOTES: Neotropical Institute Cut # 14. Bulk reel: 403. Two different males: first a higher-voiced bird (this bird sounds exactly like that of Cut 13!!), then one with a lower voice. Quality: 1. Level: +2. 7.5 ips. 203 tape.. Recording of the birds' reaction to my whistled imitation. The "low" male is in focus. Cf. also Cut 19. Quality: 1. Level: 0. 3 3/4 ips. 203 tape. Cont. of "low" male @ 7.5 ips. Quality: 1. Level: +2.
Before arriving @ km 17 I had stopped @ ~ 17.5 and heard a male sing there. I did no imitation until I arrived @ km 17. No birds were singing there. I whistled male song first; no apparent reaction. I then whistled female song; a male replied way up hill, then shortly after I heard two males nearby, one with a higher-pitched voice and one with lower voice. The latter reacted most to my imitation of female song. When "high" was singing, low was silent (during the recording period) but when I whistled female song again, "low" began singing close at hand, while "high" sang from further away (intimidated by presence of "low?").
After both birds had been silent for some minutes, I again tried imitation. There was no reaction to male song but immediate reaction to female song by two males, one in front of me (= "low") and one behind me. This bird at one place used a triplet at end of phrase! (See Cut 18.) This was recorded.
