Mixed Diglossini, Feb. 12, 1964, V
[[circled]] 22 [[/circled]]

regularly from side to side. One certainly singing. Perhaps both are. Then one flies away.

[[margin]] Uni Brun [[/margin]]
One Uni continues singing for some time. Some complete overlaps with a Brun. Then both shut up. Then Uni sings alone. Shuts up. Brun sings alone. Shuts up.

[[margin]] Uni [[/margin]]
Uni sings alone. By god! The whole upper border of its breast band seems rufescent. Can this be due to  refraction in my glasses? The malar stripes seem perfectly white. Can this be Pect, or intergrade therewith????

Now that I mention it, the song that this bird just gave was relatively rapid.

[[margin]] Uni [[/margin]]
Now the other "Uni" is singing on top nearby tree. [[underlined]] Notice that this bird has white malar stripes but no visible pectoral band. [[/underlined]] (I thought I saw this earlier when the 2 "Unis" were together on top of a tree, but decided I must be out of my mind. But this time it is definite.) I shall call this bird Uni A (and the other Uni P). Presumably intergrade with Laf???? It rang both relatively fast and relatively slow songs. I think that Uni P may have been lower down in same tree while A sang.

[[margin]] Uni [[/margin]]
These 2 birds A and P certainly seem to be ranging over the same area. Mates? Territorial rivals?

[[margin]] Brun Cy [[/margin]]
7:52. See single Brun ^[[one checkmark above Brun]] feeding silently on flowers [[underlined]] in same tree where Cy ^[[one checkmark above Cy]] is singing. The 2 birds can't be more than 2-3 ft apart! [[/underlined]] Then Brun flies off. Cy continues singing.

[[margin]] Cy [[/margin]]
Some of these Cy songs completely overlap a "Uni" song.

[[margin]] Uni Cy [[/margin]]
Notice that the faint few notes of the main body of this Cy's song phrases have definite rattle undertone, quite perceptible at close range

[[margin]] Brun [[/margin]]
Now Brun singing alone.
