NOTES: Neotropical Institute Cut # 7. Bulk reel: 36a) 5:20 AM. Yesterday I cut a trail through the forest for ~ 300 m., hoping to be closer this morning to the bird recorded in Cut 6. However, from the sound, the bird that sang this morning may be a different individual; this one has a lower voice. (But pitch changes; see next.)This bird had started with some one-note phrases but had changed to two-note phrases by the time I got on him. At the beginning these are +/- on same pitch but they gradually change in pitch and then gradually the song changes to three-note phrases. Quality: 3. Level: +5.b) When the bird stopped singing, I played the field tape (Cut #1) and soon after, from much closer, a bird started singing this song which is rather cimilar to the "dawn" (or bother?) song of M. ruficollis. (See also Cut #5.) It started quietly and hesitantly but by the time I got on it, was already becoming more normal. Quality: 2. Level: 0.c) 5:55 AM. I then played back b) and another similar song session started. Quality: 2 (1-2). Level: 0.This bird was then collected while singing (after more playback) = male #5197.Field note: by km 10 on morning of 12 July 1966, I heard two birds with song that seems to be of this species. One was to west and other to south, both far away.Note: In a recording in the 1961 unidentified file (#15), made at Ant. Pico's place, ~ 40 km north of Tumeremo (Bolivar), 8 May 1961, ~ 5:00 AM, there appears in the background a song that seems certainly to be of gilvicollis.
