NOTES: Neotropical Institute Cut # 14. Bulk reel: 169
Weather: Fair. 203 tape.
a) 7:55 AM. Natural song by pair, focused on female. Quality: 1. Level: 0.
Cont. focused on male. (Male changes song pattern.) Quality: 1. Level: 0.
(Birds were sitting ~ 15 m. apart, in separate trees.)
Song by male after playback. He then changed perch (to different tree) and also song pattern. When I first started playback, the pair flew excitedly back and forth. But apparently because I was playing only male song, the female soon dropped out and only the male flew back and forth. He was then silent, at least in my area, for 10-15 minutes, then sang again.
After recording the pair song in b), I played it back and the reaction was immediate: male and female flew excitedly back and forth at all times and in the very beginning sang together almost frenetically.
Note: When male sings, he fans out tail fairly widely, opening it at beginning of song "sentence" and not closing it until finishing that "sentence" (group of phrases). But on 10 June he fanned tail with each phrase! The female fans tail out and in repeatedly all the while she sings and doeesn't spread it as widely as the male.
b) 8:25 AM. Song by male, no further playback; song pattern is different. Quality: 1. Level: 0.
Then pair sings together. (Still no further playback.)
c) 7:00 AM. 10/6/74. Next day: Natural song by male; he then changed perch and phrase type. Quality: 1. Level: 0.
