Mixed Diglossini, Sept. 26, 1962, VIII

their preference for flowers, as well as their reluctance to enter woods. Around here, Glors are very seldom found in areas which do not include many examples of a vine with large tubular pink flowers.

The same flower occurs in the Quito region; but the aterrimas did not seem to be so dependent upon it) The Glors, Abis, and Cys here differ from the common diglossines of the Quito region in two important, and obviously correlated, aspects of behavior: (1) they are much less aggressive to individuals of other species; (2) they show a tendency to join mixed flocks, however briefly.

Do they join mixed flocks because it is positively advantageous for them to do so? If so, is this because they are more insectivorous than the common Quito species? In any case, it seems likely that they do not sing while they are associated with mixed flocks in order to avoid making the flock more conspicuous and thus attracting additional birds. 

Do they join mixed flocks merely in order to "escort" the flock out of their own territories ??? Their quietness while with flocks might suggest this.

Are they relatively un-aggressive in order to facilitate friendly approaches to mixed flocks? And / or are they relatively un-aggressive simply because it would be hopeless to try to attack all the members of a mixed flock more or less simultaneously?
