Mixed Diglossini, May 29, 1965, II.

[[margin]] Cy [[/margin]]  yesterday evening).  Hear Cy singing madly.  Phrase after phrase, all with usual Intro Notes.  Then Cy stops.  Immediately Yellowface sings 1 phrase.  Stops.  Immediately Cy sings again.  Then stops.

[[margin]] Albi? [[/margin]]  Later on, I hear some R's in distance.  Either Albis or [[underlined]] Thlypopsis. [[/underlined]]  In any case, no (other) diglossine or whitestart is audible at the time.  R's seem to be uttered by 2 different individuals.  Not overlapping one another.

R's shut up by 6:55 a.m.

[[margin]] 47 WCC? [[/margin]]  7:02.  See group of 2 or [[checkmark checkmark]] 3 small birds [[underlined]] high [[/underlined]] up in tree.  Look blackish and diglossine!  Ranging 40-60 ft up.  Uttering diglossine type twitters.  Possibly some phrases like "Ta tas-wee tasweeyoo".  [[underlined]] Could these be Aters [[/underlined]] ???  (Certainly not Cy.  Possibly WCC, except that [[underlined]] all [[/underlined]] – or both – looked dark.)  When they first begin, no other diglossine (or R's) or Whitestarts audible.  Then Yellowface sings.  Complete overlap.  Then problematical diglossine-types shut up.  Yellowface shuts up.

[[margin]] Albi? [[/margin]]  More R's a few seconds later.  I think these [[underlined]] are [[/underlined]] Albis.  Coming from areas where Albis seen yesterday.  R's stop.  Another brief match of Yellowface song.  Stops.  Then Cy sings.  Stops.

[[margin]] 48 [[/margin]]  7:23  See 1 [[checkmark]] Diglossa (species unidentified) 30 ft up in tree.  Alone.

Fog coming in 7:25.

7:30.  Hear several more peculiar diglossine type Twitters in tree tops.  Nothing else audible at the time.

[[margin]] WCC 49 [[/margin]]  Aha!  See single [[female symbol]] [[checkmark]] WCC in tree, where Twitters were heard only a few seconds ago.  Identification definite.  Bird 30 ft up.  Silent (now).  [[underlined]] And apparently quite alone! [[/underlined]]  A few seconds later, catch glimpse [[male symbol]] WCC same tree.  Also apparently alone.  [[underlined]] But then [[/underlined]] several other birds (unidentified, but definitely different species) fly into same tree.  Now I see [[male symbol]] and [[female symbol]] WCC together in same tree.
