Mixed Diglossini, Apr. 23, 1965, VIII

[[margin]] 102 [[/margin]]
Single Firebelly √ flies by alone.

8:36. See what looks like Scan flying by about 50 yds away. Feeding yellow tubular flowers. Same species I have seen both Laf & Humer feed at. No! It's a different hummingbird. But quite Scan-like in size and shape.

[[margin]] 103 [[/margin]]
Another area. 8:42. See single √ Firebelly alone. Then a sooty thrush alone. 

[[margin]] Humer 105 Cy Laf [[/margin]]
Then see single Humer √ perched top dead bush burned area as before. Silent. Flies off. A minute later, Cy √ lands on bush 10 ft away. Sings. Flies off. See same bird a little further on. Now Lafs singing in distance. 
[[margin]] Cy [[/margin]]
Cy Sings. Complete overlap. Cy shuts up. Lafs continue 8:50 am.

[[margin]] Cy [[/margin]]
As far as I can tell, Cy is almost completely nectarivorous here. 

[[margin]] 106 Cy [[/margin]]
Speak of the devil! Now see Cy √ eating large black berry. Apparently using same technique as Cy on the Pico de Espejo near Mérida.

[[margin]] Cy 108 [[/margin]]
Then see one √ Cy supplant and chase another √.

[[margin]] Cy [[/margin]]
Cy population here certainly is very dense. About as thick a population of this species as I have ever seen.

[[margin]] Cy [[/margin]]
Lots hard "Tuh" notes by Cys in neighborhood. There must be SHN's. Birds supplanting one another. One bird utters long series "Tuh" notes- forming real R as it flies to supplant another. The latter flies away immediately. 
[[margin]] Cy [[/margin]]
The supplanter perches and utters song phrase. "Triumph"! 9:01 am.

[[margin]] Cy Laf Humer [[/margin]]
All the Cys here definitely in pairs. Members of pairs stick pretty close together. If the local Lafs and Humers are paired (as seems quite possible), the mates do not stick close together.

[[margin]] Laf [[/margin]] Lafs still singing quite frequently 9:11
