Going to work in usual place, here, this morning. Arrive usual parking place 5:25 am. Just starting to get light. Partly cloudy. Not too cold.

SEE TODAY'S NOTES ON GENERAL MIXED FLOCKS.

[[left margin]] Albi [[/left margin]] 
Ca 7:40 am, 7860 ft, see dispute between 2 male Albis near birds of other species. Long aerial chases, interrupted by brief periods of perching (presumably so that birds can catch breath!). Apparently no ritualized postures or movements. But I do notice that white flank patches are very conspicuous in flight. Also visible while the birds are perched between flights. (Does this mean that their wings are slightly raised, or held out, while perching?). One or both birds utter(s) a lot of notes during the aerial chases. Quite varied. Hoarse "Tsit" Notes and hoarse "Whish" and/or "Whash" Notes. Rather different from the notes heard during dispute at La Palma in Western Cordillera!

[[left margin]] Gen [[/left margin]]
COMMENT: Although many of the 9-primaried Songbirds around here seem to be in breeding condition now, I am not sure that this is true of the local Diglossini.

Going to work on Guadelupe this afternoon. Arrive by Prime Eucalypts 3:15 pm. Cloudy. Windy. Rather cool.  

The Prime Eucalypts themselves are not in flower(altho some other Eucalypts not far away — apparently same species — do have a few flowers). The Primes also seem to be quite deserted.

[[left margin]] Humer [[/left margin]]
3:24 pm. Area where both Humers and Laf holding territories, in Eucalypts, a few months ago. See single Humer ✓✓1. Silent and alone. Low in low scrub.
