Mixed Diglossini, Aug. 2, 1965, II.  (88)                 

the Yellowface Songs [[underlined]] do [[/underlined]] seem to overlap Firebelly Songs completely at (it is my general impression that none of the Whitestarts are inhibited by any [[underlined]] Poecilothraupis [[/underlined]] Songs anywhere.)

^[[Laf]] 6:40. More Laf Song. NODWA.

^[[Laf]] 6:55. I have now heard several more brief snatches of both Laf and Yellowface Song. No overlaps. And NODWA

^[[Gen]] COMMENT: I believe that I said - somewhere in my notes of observations at the Finca "La Montaña" - that the amount of overt hostility between species of the Diglossine " social complex" probably is directly proportional to the amount of competition, for food, between them. Of course, there probably are exceptions to this general rule. Particularly when one species is [[underlined]] parasitic [[/underlined]] upon another. (E.g. see my discussion of hummingbird VIII in my notes of yesterday.)
