Mixed Diglossini, Apr. 21, 1965, II [[circled]] 45 [[/circled]]
   


[[left margin]] Humer [[/left margin]] 
Finally the two birds separate. One disappears. 
5:58. Single Humer singing exposed top Abu. Two terminal R's each phrase. 

[[left margin]] Humer [[/left margin]] 
Perhaps large part of the local Humer population is breeding now??? 

[[left margin]] Humer Albi? ? [[/left margin]]
6:00 am. Two Humers feeding in large Abu. Some chasing back and forth. Then I see female Albi in small Abu, 4 ft above ground, only 10-12 ft away. Feeding quietly. This may be the small brown bird seen to supplant Humer earlier. In any case, she is suddenly attacked and chased by a Black Diglossa, species unknown! 

[[left margin]] Humer [[/left margin]] 
I have seen Humers feeding same bush as this female Albi. 

[[left margin]] Albi? Albi? [[/left margin]] 
Female Albi back a moment later. Again supplanted by unidentified Black, almost certainly Humer. 

[[left margin]] Humer Bari Humer Bari [[/left margin]] 
6:12. Humer gives half hearted chase to ♀ Bari (identification certain) in flight. Turns away. ♀ Bari lands in small rose bush. There she is [[underlined]]supplanted by Humer.[[underlined]] Humer flies off. Then ♀ Bari flies into the large Abu preferred by Humers. Lost to sight. 

[[left margin]] Gen [[/left margin]] 
All three species of Diglossa must overlap fairly broadly here. And all three overlap Scans. 

[[left margin]] Humer Albi? Bari [[/left margin]] 
Humer feeding all over small Abu where Albi seen earlier. 
See ♀ Bari in rose bush. Then she flies up into large Abu. Then she flies down to ground. Then to small non-flowering tree. Then into another rose. 

[[left margin]] Albi? Humer Scan [[/left margin]] 
6:15. See what seems to be a ♀ Albi feeding flowers large Abu in usual Diglossine manner. Ignored by Humers feeding and disputing same tree, same time, only 4-10 ft away. Also ignored by 1 or more Scans feeding in same tree, same time, same distances!
