NOTES: Neotropical Institute Cut # 77. Bulk reel: 385
Weather: Fair. Displaying started ~ 2:30 AM; all displaying ceased before 5:45 AM.
Conflict vocalizations (including loud "ao" calls given in this context) and displays. Quality: 2+. Level: +2. LN.
This is filed for general interest, as well as for displays by additional individuals of this species. These are normal, but of special interest is one that has no break between the two parts, making it a continuous display. This comes @ ~ 52" in the second section.
In the second section the focus is to where these birds flew; there apparently still remained a pair near the first site. Quality: 2-. Level: +2.
This was apparently a two-pair conflict set above. The first section ends when one bird (presumably female) flies and a male follows her with a display flight.
