NOTES: Neotropical Institute Cut # 8. Bulk reel: 237.
Note: Relative to observation in the Turiamo road area of 26/V/73 and to Cut 8.
On two occasions heard song, first ~ 7:30 AM; on both occasions the bird sang ~ the complete "repertoire," doing so of its own accord.
Bird does not use alulas as do D. pavoninus and T. naevea. Sits with tail forward and drooped with primaries, or actually the wing itself, somewhat held out, partially open and therefore the underwing pattern is conspicuous.
The song of part b) is lacking a bit in the middle due to traffic interference and two or three phrases at the end Ð the bird stopped singing just after I turned off the recorder. The bird then sat there quietly for a few minutes when another bird began singing down the slope; the near bird left like a flash and flew down there. When I realized what was going on, I turned on the recorder without "focusing" and obtained a brief bit: the song +/- typical, that I believe by the male I had been recording, and the other song that I believe probably of a female; it is rather like the final part of a maleÕs song when he carries it to the very end of his repertoire (i.e., the "third part" as in cut 2) but is a bit more drawn out and higher pitched.
I remained in area rest of day but didnÕt hear anything like this again. The male was collected 5:00 PM. In the interim it sang periodically but would not react to playback. Finally ~ 5:00 PM it sang above the road (in the interim had always been below the road, where the presumed female had sung). I recorded some of this (not saved, as poor quality) and it did react to playback of that and was collected.
*A note found later made 2:00 PM indicated that right after this event I played back everything recorded and the bird would not react. It did sing frequently down in the same spot but sang only the "phrase 1" type of song (i.e. the "normal" phrase).
Legs: Grayish flank on these, rear part ivory; the toes are more grayish with olive cast. Soles of toes are ivory.
Soft part colors of collected bird:
Iris Ð brown with slightly grayish cast; upper eyelid from fore to aft greenish-yellow, bare skin around eye is genÕl Ð light bluish green (including above the upper eyelid!); lower eyelid is somewhat grayish with one area in center brown, like the iris.
Bill: Max.-blackish brown; in prox. part becomes pale brown to yellow at base. Mand. Ð yellowish flash @ base; distally is pinkish brownish grayish.
Weather: Fair. 139 tape. Std.
a) Song after whistled imitation. Quality: 1. Level: 0.
b) 11:50 AM. A +/- complete song, from its beginning, some time after playback. Quality: 1. Level: 0. Good recording. Very faint print-through.
Then a brief bit of recording, commented about on other side [above], that I believe presents (poorly) the song of a female and that of this male. Quality: 3. Level: +3.
Note: 2/V/73: Tried without success to whistle up this species in the area from km 33 (old 36) down to 300 m in the ravine, throughout the morning. ItÕs very dry in this area.
Note: 10/VI/73: Same site as Cut 8, cloudy @ 5:30 AM but ~ clear by 6:00 AM. During this time I heard two birds far down in the ravine below the road: one sang the "typical" song and from the other I heard only the "third part type" of song. Was this a female or only the tail end of a maleÕs song? I tried playback of a field tape loop of typical song with no noticeable success. Later I heard typical song way up the slope, still later along the road but ~ 300 beyond my position.I tried playback, in the latter place, going to where the bird had been singing and no noticeable reaction.
