NOTES: Neotropical Institute Cut # 9. Bulk reel: 306
Weather: Slightly misty. Calls by a foraging bird. Quality: 2, 1-2. Level: +3.
Each time after bird flies out to retrieve an insect it calls as it comes back to its perch. Probably upon lighting but that isn't clear from the field note. 203 tape.
