NOTE:  The reason that mixed flocks are formed more frequently in bad weather than in good may be simply that birds remain active longer (later in the morning) during bad weather and thus have more time, and chances, to come together.

COMMENT - about area above Unduavi and path to Cillutuicara[[?]]. I don't think that the average density of honeycreepers, warblers, tanager, and bush-finches here is any greater than in the Quito region. I.E. the frequency of mixed flocks here is probably not due to greater density of population.

About the garden area of lower La Paz. The situation with regard to mixed flocks here now seems to be much the same as during my last visit. Thrushes, [[underlined]] bonariensis [[/underlined]], [[underlined]] gayi [[/underlined]] Orange bills, etc., may all occur quite close together, especially when feeding in the same places, but all these associations seem to be purely casual. No signs of special inter-specific preferences. No signs of organized flocks, stereotyped and frequent following and or joining responses-among the species with which I am concerned. Very few signs of ultra-specific gregariousness either. Probably only a few family parties. (Again, goldfinches may be an exception to all these generalizations.
