[[underlined]] Diglossopis, [[/underlined]] May 27th, 1960, II.

[[black marking]]
single song phrase as "Tsit Tsit Tsewee Tseweeyoo".

There was considerable variation in these songs.  Some songs were introduced by really never more than 2 "Dit" or "Tsit" notes.  Some songs included definite R sounds.  For example:
"Tsit Tsit Tsewee Tseweeeeeeeeeeeyoo".

These songs may be distinguished from those of the small black Diglossa here by 2 features.  I They are always or almost always introduced by the "Dit" or "Tsit" CN-like notes, which appear to be integral parts of the song.  (The songs of the small black Diglossa may be preceded by CN's, but these latter appear to be more sharply set off from the song itself.)  II The various notes of the main part of the song phrases of the Diglossopis are more "distinct", in some way, than the notes of the song phrases of the small black Diglossa.  Apparently fewer also.  (In any case, we could attempt to make transcriptions of the songs of the Diglossopis, while we could not attempt to make transcriptions of the song of the small black Diglossa.)

As far as I could tell, the songs of the Diglossopis were delivered from completely unritualized perching and feeding postures.

David caught a glimpse of one bird in a bush, with its wings stretched out horizontally, waving a little.  This may have been part of a BU pattern.  Unfortunately, we could not tell if the bird was singing or not at the time.

These birds did a lot of TF's.  I saw one bird do both U-D and D-U types.  They also did WF's;  probably less frequently than TF's.

They seemed to be feeding on flowers in exactly the same way as Diglossa – and on exactly the same flowers.
