[[underlined]] Diglossopis, [[/underlined]] May 24, 1962, IV

(This is almost certainly the same bird that omitted introductory notes in its songs the first day I arrived this year).  Then the bird flies to several trees.  Sings in each.  Does [[underlined]] not [[/underlined]] utter "Seeeet"s in flight.  Then disappears.

8:25 a.m.  Come across same "A" as before.  Apparently alone.  Singing repeatedly on to of bush.  Songs without introductory notes or "Sreeeeeeee" components (which I shall call "SR" from now on).  Then flies up into adjacent eucalypt.  Continues singing.  Then a [[male symbol]] [[underlined]] aterrima [[/underlined]] about 75 feet away begins to sing to.  These are [[underlined]] undoubtedly [[/underlined]] the same 2 birds I watched singing together in the same place yesterday!!  They seem to be real territorial rivals.  Sometimes their phrases were alternated.  More often they were partly synchronized.  Sometimes the [[underlined]] aterrima [[/underlined]] began a phrase a second after the "A"  Sometimes the "A" began a phrase a second after the [[underlined]] aterrima. [[/underlined]]  Eventually the 2 birds shut up.  I think the [[underlined]] aterrima [[/underlined]] had the last word.

At the same time that this "duel" began, I noticed that "A"s phrases had begun to include both introductory notes and SR.  There seems to be a definite (but not invariable) correlation between SR and introductory notes.  Which probably means only that phrases with introductory notes tend to include more, and more accelerated, notes than phrases without introductory notes.

It is possible that phrases with introductory notes and SR are more strongly hostile than phrases without such elements.

8:47.  The same 2 birds are engaged in another "duel" as before.  In this case, the [[underlined]] aterrima [[/underlined]] definitely has the last word.

Came back to C area 8:55.  Find a single C singing, in tree and in bushes.  All songs with introductory notes & SR.  Occasionally utters
