Mixed Diglossini, Oct. 27, 1962, IV  

silent. No obvious fight. Cys soon move on.

[[left margin]]  Laf [[/left margin]]
R's in Laf song sometimes or always part of triplets "ta-ta-zreeee" [[waves drawn under e's]].

[[left margin]] Humer [[/left margin]]
A Humer repeatedly begins singing just after a Laf has begun. Wide overlaps. Finally Humer stops, Laf continues.

[[left margin]] Laf Humer [[/left margin]]
So the Laf-Humer relations do really seem to be different from relations between any other diglossines I have watched.

[[left margin]] Laf [[/left margin]]
Two Lafs, presumably mates, sitting about 2 ft apart, top of same bush, both singing continuously. No (other) overt indications of hostility. Then both fly off, together, uttering "Seeet" Notes.

Starting down hill again 8:08 am.

[[left margin]] Humer  [[/left margin]]
Quite a lot of the Humers around here seem to be in pairs.

[[left margin]] Laf [[left margin]]
Back to main Laf area 8:29. Lafs still in full voice.

[[left margin]] Laf Humer [[/left margin]]
It is not surprising that specific separation between Lafs and Humers tends to break down, to some slight extent, when the birds can see one another. What is remarkable is that specific distinction tends to
