Two species of Saltators around here, the Buff-throated and the Streaked [[red hatch marks]] =Buff-throated= [[underlined]] maximus [[/underlined]] [[gray hatch marks]] =Streaked= [[underlined]] albicollis [[/underlined]]
One "♂" of each species has sat alone in the top of a large fairly bare tree, uttering distinctive notes. Both sitting in quite erect postures, apparently unritualized. The notes themselves were usually doublets "Wuh-hooo", the second part of each doublet often having a noticeable quaver. The voice of the Streaked seemed to be much clearer & purer than that of the Buff-throated. Both birds occasionally uttered single notes instead of the doublet. And the Buff-throated (at least) occasionally uttered triplets. 

Now one of the Buff-throats came back to the same tree, sat in the same way, but uttered different sounds. More elaborate: "Duh duh duh duh duh whoooo-ooo". Perhaps like this -- __ -- __ -- [[last line starts on the blue line of notepaper and gradually raises]] ??? The first part very rapid, almost semi-R-like, the latter a nice clear whistle. The whole thing somehow reminiscent of the WS's of the Blue and Palm Tanagers-more or less the same "type" of song. (I think I shall call it WS too). After the bird had sat and uttered about 3 of these WS’s; another Buff-throat came and landed on a branch a few feet away.  Also uttered a few WS's.  The first bird also uttered a few more WS's in the next minute or so; but there didn't seem to be any particular arrangement of the WS's of the 2 birds, i.e. they weren't singing
