ally, that I have never seen a Streaked perform anything like a "Flight song" here.)
     At the Rio Piedras, the only species I have seen really high in tall trees (70ft or more) is the Buff-throat. Both the Black-cap & Streaked seem to stay lower (at heights of approximately 12 to 30 or 40ft), at least most of the time. The Streaked is the only species I have seen in very "open" second growth, in bushes & trees on the edge of pastures; but it also occurs quite frequently in the thicker second-growth where I have been watching the Black-caps.
     I think I shall drop the term "WS" as applied to Saltators, and just use the term "song" tout court.

Black-capped Saltators are by far the commonest species of Saltator in the neighborhood here. We saw at least 3 pairs of Black-caps here in the first half mile or so of the Las Cruces Trail. (The only other species of Saltator I think I have seen here is the Buff-throat. I may have seen one or two apparently single Buff-throats around; but I cannot be sure of this.) The Black Caps were very noisy and conspicuous; and may well have been beginning the breeding season.

I think that I understand the song & related patterns of this species a little better now.
     
We came upon one pair around 7:00 a.m., which appeared to be engaged in a territorial dispute. At least 3 birds flying around from
