Atlapetes, May 25, 1960, II   

a rattle in rhythm.)

Later in the morning, David observed one bird, apparently all by itself, utter a series of "rapid, loud, harsh" notes - which were almost certainly closely related to, or identical with, the notes I have transcribed as "Cheeo" or "Teeo" on preceding pages.

Still later, we heard one bird utter another distinctive type of "song." (We couldn't actually see the bird when it uttered this vocalization, as it was hidden deep in a bush; but it flew out of the bush a few seconds later - followed by its mate.) This "song" began with 3 "Dzoowee" notes, which were followed by an obscure warbling bit, which was followed, in turn, by a rattle.

I must say that I am greatly impressed by the great variety of vocalizations of this species!

In mid-morning, we heard another burst of peculiar sounds which were probably uttered by this Atlapetes. Coming from deep inside a tall thicket. A whole burst of harsh notes. Uttered singly, or in doublets, or in triplets, or in quadruplets. _ or _ _ or
_ _ _  or _ _ _ _. Each one of these notes might be transcribed by something like "Wauh" or "Dauh" They all or almost all had a pronounced rattle undertone. They were
quite reminiscent of the HAC notes of many other species; but rather more mechanical sounding. They were occasionally interspersed with "Cheeoo" or "Teeoo" whistles.

David saw an Atlapetes moving about in the bush when their sounds were being uttered, and the sounds seemed to move down the bush as the bird moved. Then the bird flew out of the bush and away. David said that he is almost certain it was a rufinucha. It looked comparatively pale and grayish underneath, but did seem to have (at least) a yellow throat.
