Mixed Diglossini, Feb 9, 1964, III

os the Bari. Pointly less advanced (Veg the Quito and Iarwa birds tree top)

all quiet 7:00 a.m. So perhaps the breeding season isnt very far advanced.
 NOTE - Juest to check - the altitude here according to my altimeter now id 7650 ft.
As far as it goes, this mornings observations support the theory that all the local species have to be singing frequently for mutual inhibition of song to work. Even the Brun sang quite frequently at the peak of activity this morning.

7:20 Bari back singing again from some perches as before. Some of the R's seem to have a brief rasp or hoarse note at the very end (So probably did his R's earlier this morning, but I did not pay attention to it)
The territory or home range of this Bari seems to be quite large. The hedges on 3 sides of a very large grassy field, several hundred feet across. But he seems to spend more time on two of the sides (where the hedge is thickest) than on the third.
Walking on down road a bit 7:28
7:36 See another single Brun in hedge. Alone. Silent. Flies up in Eucalyptus then lost to sight.
Incidentally, all the Bruns around here seem to be "pure".
No obvious signs of inter gradation with Ater.
7:45 Come to another area thick wet looking-scent. Altitude 7650 ft. See a single Thrich alone. Big, bonarenses sooty. Yellow orange bill and legs. No eye ring. 
Also see two bright bonarenses. Not together. Both alone, one utters TW patterns.
