NOTES: Neotropical Institute Cut # 4. Bulk reel: 347
a) 9:00 AM. All short songs. Note that the bird now hardly ever uses what I have called before "typical" short phrases (the hoarser type) but almost entirely short song phrases. Quality: 1. Level: 0. No parabola. 203 tape. LN.
b) 1300 hours. A period of continuous singing with long song phrases. Recording level good and no tape saturation. Quality: 1. Level: 0.150 tape (Std.) with a bit of 203 (LN) at end at 1:30 PM.
Note: General impression is that continuous singing, with long songs, is mostly limited to the mid-day period.
c) Again short songs. Some of this is with natural interval between songs, others not. Quality: 1. Level: 0. 203 tape. LN.
(Final two songs are good examples of "short song phrases" for analysis.)
Note re: Cut 41) & c): The only explanation that I can so far offer re: the bird's having practically ceased the "typical" short phrase, using almost exclusively the short song phrase now, is that (apart from possible adaptation to its new surroundings) since last week the two "females" were separated and there was thus no more of their squabbling sounds, nor of the trill "song" that one of them gave. Thus there might be a different context in which the male now operates.
