Song by male. This is ~ 1/2 way between the cliff colony of Aeronautes and km 17. The bird had been singing naturally at some distance but came in attracted by my whistled imitation of male song. Has print-through but saved as record of another individual (or could it be one of the km 12 birds in the locality?). After the recording I tried male song several times and each time this bird flew back and forth in reaction but did not sing. Also, when perched it did not extend nor move the alulas; the tail was somewhat fanned out and the bird looked around, as if trying to locate the "intruder."

I then whistled female song and immediately the male started singing. Unfortunately, I could not see him now to see if he moved the alulas. After a pause of more than ten seconds after the bird stopped singing, I again tried male song imitation; no result. I then tried female song and the male reacted immediately vocally and I was surprised to find he was apparently still on the same perch. This same thing was repeated after a similar delay: same results.

In all these trials, although the bird reacted vocally, it remained always hidden, on the same perch and would not fly back and forth.

On 08May1973, I heard male song at km 13, near Guamito, @ 6:55 AM. I also heard male song on 02Jun1973 at 9:25 AM when I was at the 320 m. level in the ravine below km 33. The bird's position was uncertain but appeared to be at about my level or slightly on the slope across the ravine. I had tried to whistle up this species and also D. phasianellus all morning. I was in the area and also walking from highway down and going back up again, with no success. It is very dry in the area.
