Cerro Pichincha

[[underlined]] Diglossa [[/underlined]], I

Watched the same birds of the little black species again today.

[[pink marking]]
One [[male symbol]] interjected R's into the middle of his songs, when he was apparently all by himself.  Not all his song phrases included R's;  but at least a third did.

I observed two cases of what were probably actual attacks or supplanting attacks deep in the shrubbery.  Involving different birds.  Each attack was accompanied by an R, followed immediately by 2 distinct notes: "Sreeeeeeeeee Ta-ta" [[image: drawing perpendicular line]]
These terminal notes may have been "intention movements" of song.


Cerro Atacaso

This afternoon we went up Atacaso looking for Diglossas.  At one point, a couple of thousand feet below where [[underlined]] aterrima [[/underlined]] is so common, all the Diglossas we could identify were of the small black species.  (Unfortunately, we couldn't investigate the region where the ranges of [[underlined]] lafresnayei [[/underlined]] and the small black species must meet or overlap, as the rain & fog came down.)
