Mixed Diglossini, Sept. 2, 1965, V 

[[left margin]] Scan LCH Glor [[/left margin]]

Scan(s) uttering "chuk" Songs again. NODWAH LCH back on lookout 7:58. Then flies off to attack a greenish hummingbird (almost certainly not Scan - apparently smaller). Both birds fly away. Immediately a single Glor ✓✓78 [[black & blue checks, blue #]] flies into area!!! Feeds up hill. Then flies off again.

COMMENT: The social situation here (on this wide of ravine) seems to have become greatly simplified. A few days ago LCH, Scan, Glor, Cy, and Coer all occurred here quite frequently. Now only the Cy and LCH visit this particular site with appreciable frequency. 

Scan(s) have come here only once (or not at all) today.

Glor(s) certainly are visiting the site much less frequently than a couple of days ago.

Both Scan(s) and Glors seem to have moved out. But they have gone only a few yards away. (It might even be misleading to say that they have "moved." Perhaps they have only "stopped visiting" the parts of their original ranges where Cy(s) and LCH have become dominant.) Incidentally, this means that Cy and Glor ranges are adjacent here now, but not overlapping. (Of course, the ranges of the two species here are apparently never well stratified.)

It is interesting that it is the Cys and not the Glors who seem to have won the battle for the Diglossa niche here. (The victory of the Cys is even more decisive than the above account would imply. Altho the
