Mixed Diglossini, Aug. 11, 1965, VI.  (74)

yesterday. Utters occasional soft "Seet" Notes. Then disappears.

^[[Coer]] It looks as if these birds may follow a regular routine, regular pathways around their territory.

Leaving 9:45 am.

NOTE: Horacio [[underlined]] thinks [[/underlined]] that the small mountain here is called "San Gerardo." And he is [[underlined]] sure [[/underlined]] that the name of the Finca here is "La Palma".

^[[Coer]] COMMENT: I am surprised that I have not heard one or both of the Coers near PII Singing. Is that because the mates keep together.

^[[Coer]] In general, it is my impression that almost all Coers Sing relatively rare. The species certainly appears to be "less" vocal than [[underlined]] carbonaria [[/underlined]] s.l., [[underlined]] lafresnayei [[/underlined]], or [[underlined]] cyanea [[/underlined]]. Almost as quiet as [[underlined]] albilatera [[/underlined]]! Why??

^[[Sitti]] Working along highway, in "permanent fog zone", this afternoon. SEE TODAY'S NOTES ON GENERAL MIXED FLOCKS. ca. 3:30 p.m., see pair of Sittis with mixed flock. [[underlined]] At 8140 ft. [[/underlined]]! Surely this is the lowest altitude at which I have ever seen Sittis??? Do they come down to unusually low altitudes in very humid, foggy areas???

^[[Sitti WCC]] It is interesting that there were no WCC's with this flock. Although I have seen several WCC's with other flocks earlier this afternoon. Are WCC's and Sittis less apt to associate with one another at relatively low altitudes than at relatively high altitudes???

^[[Cy]] ^[[Cy Albi]] Considerably later, see another mixed flock which includes a Cy. This Cy quite [[underlined]] low [[/underlined]] in scrub. Ranging 1-10 ft up. Usually in lower half of this range. It is my impression that the lower altitude Cys here [[underlined]] may [[/underlined]] come down low in vegetation much more frequently than the higher altitude Cys. When they do come down low, they come into what looks like perfectly typical Albi habitat. Unfortunately, I have never seen a Cy
