[[underlined]] Diglossa, [[/underlined]] I.

Watching in the same old area again this morning.

[[pink marking]]
To my surprise, we found one [[male symbol]] of the small black species near this area this morning.  Singing.  Perhaps significantly, this [[male symbol]] had selected a territory which received sunshine before the territories of all or most of the [[male symbol]]'s of the blue-spotted species.

We found it very easy to distinguish between the songs of the [[male symbol]]'s of the 2 species, even at a distance.  The song of the small black species may be considered an "aimless twitter".  It also seems to have a definite "usual" length.  The song of the blue-spotted species is stronger and slower;  compared of comparatively distinct notes;  and (almost certainly) much more variable in length.

[[blue marking]]
I got some more detailed information on the songs of the blue-spotted [[male symbol]]'s.  There is considerable difference between the songs of different individuals at the present time.  One [[male symbol]] we watched sang something like "Zraa Zraa Zraa [[underlined]] Zraa-a-Zaa [[/underlined]] Zraa Zraa ....."  Mostly single notes.   Only a few "doublets" (underlined in red above).  Other [[male symbol]]'s sang almost nothing but doublets.

As further confirmation of the hostile nature of the songs of this species – it should be noted that, several times today, one or more males who had been silent for at least several minutes suddenly began
