NOTES: Neotropical Institute Cut#26.Bulk 62; Extra cutlength 8:53 203 tape. a) 7:00 AM. Weather: Clear. Natural song. Quality: 2. Level: +5. Then after playback. Quality: 1-2. Level: +5. Then after more playback. Quality: 1. Level: +3. 7.5 ips. (Columbina passerina good in background in last ~ 1/2 of this recording.) (Faint print through.) Then after still more playback; now being baited by Mimus gilvus. Quality: 1. Level: +3. b) 7:40 AM. Weather: Fair, hazy sun. After long silence bird started to sing again (no interin playback). Quality: 1. Level: +3. 7.5 ips. Then after more playback. (I don't know if bill snap at end is by owl or another bird.) Quality: 1. Level: +3. 3.75 ips. c) 8:25 AM. While I was dictating the notes which are transcribed overleaf, the owl suddenly burst into "alternate song." This was the first time in all the process so far that the bird gave this song, and I think it resulted now due to arrival of the bird's mate; in any case, a second owl had arrived. 3.75 ips. d) I then moved about 100 m. away and tried all the jardinii playback again. Voice notes on tape (no reaction to any except the one-note succession and that only after repeated playback). Recordings here are owl's subsequent vocal reaction. Quality: 1. Level: +3. 203 tape. 7.5 ips. e) 12:40 PM. Weather: Fair. The owls kept singing periodically through the morning after playback discontinued (~ 9:30 AM),so at 12:15 PM I repeated the playback. This is the song recorded after finishing. Note: One bird heard first; then the pair and s ome alternate song. I then repeated the playback (of jardinii "alternate"). One bird stopped singing and there was no reaction. (I was watching bird; it then flew back to where it had been singing. I then played both complete song and one-note succession and got no reaction.) Quality: 1. Level: +3. After some delay (~ 15') played jardinii one-note succession 2x (the series) and got no reaction. Then I played its own song and before even the second phrase was complete, the owl flew in and looked about with excited head bobbing and then flew away even though I continued playing. I then played the recently recorded "duet" of this pair. They came closer but not right to me. (See Cut 13b of Saltator orenocensis.) f) ~ 2:00 PM. [Note in margin:] "Note the extreme similarity of the two voices!" With the owl singing I again tried playback, leaving one recorder focused on the owl. The recording begins with the field tape sound, then continues with the owl; then field notes with regard to playback observations, at new location I found that bird reacted best to jardinii one-note succession if I delayed some time before playing it, rather than playing it immediately after playing the jardinii complete song. About 15 minutes after previous playback and I tried again playing the one-note succession song of jardinii and got no reaction (now ~ 9:00 AM); then after several minutes delay tried playing the bird's own song and got an immediate reaction. But then a second playback of its own song brought no reaction (bird habituating?); however, I then played the brasilianum alternate song (part c of this cut) and bird reacted immediately.. Note the extreme similarity of the two voices! Quality: 1. Level: 0. 3.75 ips. Notes after 12:15 PM playback: No reaction to jardinii alternate song played through 2x. Then played complete song 2x and got no reaction. Then played jardinii one-note succerssion and was not aware of any reaction. Then I played the recording of this owl and immediately the owl came in and perched beside me and in two or three minutes started singing; after ~ 10 phrases I recorded it and this is the recording of part e). Note of 2:00 PM - Playback of jardinii alternate caussed owl to stop singing briefly but it soon resumed, apparently on same perch. With playback of the complete jardinii song the owl definitely stopped singing but I didn't see it come in (it apparently remained on same perch). then I played the one-note
