Mixed Diglossini, July 17, 1965, V  (71)

s.l. is rare here (as well as in the southern part of the Western Cordillera). But, if no, why is it that [[underlined]] brunneiventris [[/underlined]] is the local subspecies??? Merely an historical accident??? (The range of [[underlined]] D. lafresnayei gloriorsissima [[/underlined]] may also be revelant in this connection -altho I don't see exactly how.)

^[[Gen]] The general situation in the first area visited this morning may be summarized as follows. Only 2 species present. Albi and Coer. Albi is common. Coers less common (population much less dense). At least partial overlap territories of the 2 species. No indications overt inter specific hostility. Mutual inhibition of Song apparently perfect. (The local Whitestart almost certainly involved in this mutual Song inhibition. As far as I could tell this morning, its Song did not overlap those of either Albis or Coers.)

Santa Elena

Arrive one of the areas where I worked in 1962, 8300 ft, 5:25 am. Just starting to get light. Quite a lot of bird sounds. Apparently largely Andean Sparrows.

^[[Albi Cy]] (Single Albi alone, several Cys in mixed flocks).

^[[Gen]] The assemblage of Diglossas here is [[underlined]] very [[/underlined]] reminiscent of the corresponding assemblage at Minchique. In both regions, Albis and Cys are comparatively common (the Albis being essentially non-gregarious while the Cys associate with mixed flocks relatively frequently), Coers are seen occasionally,
