Diglossini, Apr. 18, 1972, III.   C.

tail. Generally dark green. Purple on forehead. Bluer green bright throat patch. Feeding on large cup shaped yellow flowers. Flies away.

A few minutes later and a few yards further on, seen single [[female symbol]] Plumb. Obviously alone. Silent. In garden. Feeds on dark pink small Gladiolus. Also same type of yellow cup shaped flowers taken by hummingbird. But definitely cutting in from side. Presumably not same [[female symbol]] seen earlier.

7:55 a.m. Arrive back at first area. First [[female symbol]] Plumb feeding on Datura flowers as before.

Stop observations here 8:20 a.m. Quite dense drizzle, bajarique, seems to be settling in.

The rarity of nectar-feeders here applies to individuals as well as (or even more than) species.

9:30 a.m. Going to work around the Dahlin's house. This area is comparatively low. Probably only a few hundred feet above the El Nato lava plain (although several miles along road. The Dahlin's claim that one or more Diglossas do (does) feed at Fuchsias at this lower level. Certainly there are holes in corollas. The Dahlin's have also seen two species of hummingbirds here feeding on the same Fuchsias. Their accounts would suggest that interspecific encounters among nectarivores may be "random". But Jane Rosenthal did see one fight between a Diglossa and
