avoid overlapping non-diglossini Songs? I think so (viz Guasca in 1962). This trait must be correlated with the partial breakdown of mutual avoidance and inhibition among the Diglossini themselves here.

I. The frequency of inter-specific hostility here is not immediately correlated with density of population. The group of Diglossines around the Prime Eucalypts is the most crowded population I have ever seen. The population above Guasca is much like some populations near Quito. the population at Agua Bonita seems to be comparatively sparse.

II. It is interesting that the "flocks" of Diglossines have been seen only in association with introduced plants (Eucalyptus and Abutilon). I wonder if there are (or were) any native plants which attract(ed) flocks???

[[left margin]] Coer Cy [[/left margin]]
III. It has just occurred to me that I probably have never seen Coers in areas where Cy were absent. This is, perhaps, rather surprising -- as the ecologies of the two species seem rather different.  Do Coers pick out area as "suitable for colonization" because they see Cys there????
