Mixed Diglossini, Sept. 26, 1962, VII.     

[[left margin]] Cy  Inter [[/left margin]]
At one time, there was a single Cy associated with this flock. In small tree. As far as I could tell, it never came very close to the Inters. It appeared to leave the flock after only a few minutes. It did not sing while with the flock.

[[left margin]] Gen [[/left margin]]
As far as I can remember (but I must check my notes on Albis and Cys on the Pico de Espejo), none of the local diglossines has sung while associated with a mixed flock. Perhaps the presence of individuals of other species inhibits song by the local diglossines. This did not seem to be true of the Quito birds. See discussion below.

[[left margin]] Glor [[/left margin]]
As soon as the flock moved on, a bird which I presume to be a Glor (altho I couldn't see it) sang typical Glor songs in an area in which the flock had been a few minutes earlier. This might suggest that the Glor was "relieving his feelings" which had been suppressed by the presence of the flock.

Let me see if I can make a partial summary.

[[left margin]] Gen [[/left margin]]
The local diglossines are more clearly separated by habitat preference than than are the diglossines of the Quito region. Is this an indication that some of the local species have arrived only relatively recently?

[[left margin]] Glor  Albi [[/left margin]]
(The distribution of Glors is rather puzzling. Seem to prefer drier habitats than Albis. Do not occur inside forest like some Albis. May also extend to higher altitudes than Albis. Incidentally, I have become convinced, gradually, that there are no Albis here in the area where Glors are so common. The Albi-like songs may be uttered by another species. The Glors seem to be separated from Inters by
