NOTES: Neotropical Institute Cut # 13. Bulk reel: 467
Weather: Fair. Natural song. This song seems rather different and when I first heard the bird couldn't place it. The bird then changed its song and the new song too seems very aberrant. Quality: 1. Level: +5.
Then after playback, voice still aberrant. Quality: 1. Level: +5.
Bird then collected [= male #6690].
