NOTES: Neotropical Institute Cut # 26. Bulk reel: 205
Weather: fair; moon, 1 day before full. On site @5:13AM. Sky begin lighten in the east @~5:25AM. First display @ 5:32AM, up east ridge; then other displays up west ridge (all far and not recorded). Reflector then pointed up to east ridge.
A few "growl" calls, then a display, bird fairly far up east ridge.
After this there were some more growl calls but apparently no more displays, although traffic made observations difficult and I may have missed one. Quality: 2. Level: +5.
