NOTES: Neotropical Institute Cut # 3. Bulk reel: 241
Time: ~ 7:30 at end. Weather: Fair. Dance display. I was trying to record the song of this species, not with much success (none used as better in Cuts 1 & 2 and to follow), when behind me I heard a "buzzing" sound and almost immediately swung the parabola around to record the sequence of this cut, what proved to be a dance display of this species, much longer than anything experienced before (a suggestion of it in foregoing cuts)or since, although I spent several hours on this same spot on this and succeeding days, hoping to be able to see the action bettter than the interfering foliage allowed me to do this time.
Voice notes of the little I could observe at this time are in the notes.
Note: Before this display occurred I had played back several times the song I had been able to record.
On a subsequent occasion with display, very brief compared to that recorded, and with a dance that corresponded +/- to the first part of the recorded sequence, I could see that a bird was sitting on a twig in front of the displaying bird and it appeared to have the "bib," i.e. the part above the dark crescent, partially extended and as if it were allowing the displaying bird to "blow" air into its face and breast. This bird was sitting on the perch crosswise in +/- normal position but with the head slightly thrown back. (It appears from subsequent observations that in portion of display where I couldn't see tail position, its tail was probably down.)
Quality: 1-2. Level: +10.
