Watching a single, presumably ♂, Streaked Saltator "singing" here. In usual erect posture; with tail-down. These songs seemed to be more or less typical of the  most common forms of song of this species. Relatively slow, with relatively larger notes than any of the Wbls of other species, with which it may be more or less completely homologous
  The complete songs of this bird might be transcribed as follows
[[images of 3 dashes, a large space between the first and second, second and third are placed lower then the preceding lines; diagonal line, squiggly line; underneath is written:
" duh duh-duh  wheeeeooooo [[wavy line]]]]"
I am not absolutely certain that the diagram of the 4th note, which is relatively long and whistle-like is really correct. It is possible that the pitch is descending in all or most 4th notes. [[downsloping line]]
It is also possible that there is considerable variation in the 4th notes from time to time. It is possible that some are ascending while others are descending.
This is obviously the same thing I called "WS" in my earlier notes on the Streaked (e.g. Apr. 7, 1958, p.9; and Apr. 10, 1958, pp 10 and 11).
I am sure that this must be closely related to the songs of other species of Saltator; but the exact details of the relationship are still obscure. It is conceivable that the whole "complete" song of the Streaked; such as sung by the ♂ I watched  today, is strictly homologous with the Wbl of the Buff-throat More probably, it is strictly homologous with the whole "WS" of the [[Greyish?]], and the Wbl + See Notes of the Buff-throat and the Black Cap. If so, it is
