Mixed Diglossini, May 27, 1965, III.  (27)

of Cy songs, and [[underlined]] begins [[/underlined]] to sing before Cy has quite finished.  Thus leading to a lot of [[underlined]] partial [[/underlined]] overlaps.

^[[Cy]]  Cy is certainly the species Singing most frequently here.  Followed by Yellow-face.  Slate throat Singing least frequently.  As far as I have been able to tell, Slatethroat is [[underlined]] still [[/underlined]] interjecting Song phrases only when both Cy and Yellow-face are silent.

This may be comparatively "easy" for Slatethroat because its Song phrases are shorter than those of either Cy or Yellowface.

^[[Cy]]  5:58.  Now 1 Slatethroat [[underlined]] does [[/underlined]] Sing 1 phrase while Cy is in full voice.  Complete overlap.  Slatethroat shuts up.  Cy continues.

^[[Cy]]  Then brief period general quiet 6:00 a.m.  Then more Cy Songs.  At longer intervals now.  But still frequent.  Cys [[underlined]] must [[/underlined]] be in breeding condition here now.

^[[Cy]] See 1 Cy.  In [[underlined]] small [[/underlined]] tree above second growth scrub.  15-20 ft up.  Makes 1 "flycatching" flight!

^[[Cy]]  Cys shut up.  Yellow face Sings.  Shuts up.  Cy Sings.  Shuts up.  Yellow face Sings.  Shuts up.  Cy Sings.  Shuts up.  Yellow face Sings.  Shuts up.  6:04.  No overlaps at all.

Fog is approaching now.  Visibility is poor.

All quiet 6:07 a.m.

^[[Cy]]  6:12.  Cy Singing again.  See bird.  In isolated tree.  40-50 ft up.  All Song phrases as before.  Song posture rather low diagonal.  Tail quivers visibly with Twitters.  Presumably just as result of physical effort of producing the notes.  The Cy ignores 2 swallows and 1 flycatcher perched 5-10 ft away.  Then shuts up.  Feeds on clusters of white flowers in tree.

6:23.  Now it is clearing up.  [[underlined]] And [[/underlined]] getting warm!
