Song type 1 = SO-SOO-la; 2 = SO-SO-LA; 3 = SO-LAA.O
a) 10:00 AM. A type 1 with lower frequency. This bird was on other side of cano at this time. With whistled imitation it moved away (from later develoment I suspect it was trying to find a more appropriate phrase, i.e. more cover, to cross the cano to my side) and then fell silent. Quality: 2+ to 1-2. Level: +3.
b) 2:30 to 3:30 PM. Bird now on camp side of cano. First phrase natural. Bird was singing regularly but until I reached the site and set up it fell silent after this phrase. Quality: 2. Level: +3.
At one point during the bird's natural song session it seemed to "slow up" a bit. Then another bird was heard to sing fairly close, after which this bird again sang more actively. Then while I was trying to focus on this bird I'm pretty sure I heard some "clucking" sounds. So perhaps this male attracted a female to him and then, perhaps after copulation(?), he stopped singing.
I then used playback to bring bird into song again. Quality: 2- to 1-2.
What was almost certainly this bird was collected; it decoyed in silently and circuitously = male #8850.
