NOTES: Neotropical Institute Cut # 33. Bulk reel: 30 Weather: Fair. a) 5:30 AM. "Dawn-type" song. Reaction to playback of field tape. Quality: 1. Level: +5. Then one-note calls. Quality: 1. Level: +2. Then "dawn type" song again and this may possibly be a different individual. Quality: 1-2. Level: +2. Then a different type of "dawn song" reaction. Notice that just before this there is one single "bark." It isn't clear but there may be two birds involved. However, there's also one such "bark" at end which seems pretty surely to be by the "singing bird." Quality: 1. Level: +2. (Note: This is same bird.) b) 6:40 AM. No further playback. One-note calls from two birds. Quality: 2. Level: +10. Bird in focus is on west side of road and is the last bird involveld in part a), and note that it calls in groups of two and three notes. Quality: 1-2, 1. Level: +5. Then after playback of above, bird continues +/- same. Quality: 1. Level: +2. Then some recorded "off-focus." Quality: 2. Level: +10.
