Song type 1 = SO-SOO-la; 2 = SO-SO-LA; 3 = SO-LAA.
Bird #3: this is a type 3 singer. Quality: 2+ to 1. Level: 0. 203 tape. LN.
This bird heard yesterday AM in same place; also Dick Zusi whistled him up yesterday PM. This afternoon bird was not singing but I went into woods and whistled type 1 song and soon he was walking around me. Note two-tone whistle in certain places. Quality: 2+ to 1. Level: 0. 203 tape. LN. Copied N-4.2 to N-IV. (Orig. copy, not filt.)
This bird #3 was on the other side of Cano Caracol and on east side of road just beyond bridge. This bird was much less timid than most and as long as I remained still he would walk around at times exposed to view no more than six m. away. Usually, however, he would stop in a position +/- concealed by foliage and sing for protracted periods.
Throughout the time I occasionally whistled type 1 song. Toward end I also whistled C. cinnamomeus phrases. i could tell no difference in the bird's reaction but by then it had been well "worked-up." In fact, apparently due to the stress, this bird frequently ysed a two-tone whistle, i.e. it produced sound at two sources, presumably the membranes in each bronchus.
At no time was a second bird seen with this one; however, it did give quiet whistle of type 1.
Description of bird's action when emitting song phrase: Bird raises self up, stretching neck and fore part of body upward, with the head and bill pointing upward ~60¡ from horizontal. The bill is open ~20¡ during song.
Bird #3 was seen to have back indistinctly barred with black; the rump and upper tail coverts barred black and buff. Legs "red."
Note: Added at end some of the loudest phrases of this cut, copied from SN and the orig. SN tape, after the partial correction of the SN motor noise. 3 Mar 1974.
