Mixed Diglossini, Sept. 30, 1962, II

[[left margin]] Laf [[/left margin]]
A few seconds later, the Laf stopped singing A few seconds after this, a single Laf appeared in flock not far from Sittis and Rufs. Almost certainly not bird that had been singing. I am almost certain

that the actual area the flock was in belonged to another Laf, and it was presumably the latter who joined flock. In any case, the Laf that joined the flock was silent or uttered no more than "CN"s while it was with flock. Much of the time, it was close to the Sitti and Rufs. Apparently no reactions between any of them, except, possibly, once when the Laf chased another bird. I could not identify the latter. It may, conceivably, have been the Sitti. Certainly not either of the Rufs.

All the Diglossini in this flock were followers. Kept toward rear, with three Atlapetes? (no. XV). Once the Sitti flew across the road immediately after a PR Atlapetes. None of the other diglossines reacted to any of the other members of the flock in such an overt conspicuous manner.. I.E. Sitti (like Inter) may be more highly gregarious than any of the other local diglossines.

After approximately 5 mins., the flock seemed to turn down hill. Probably not followed by the Laf. At least, a few seconds later, a Laf sang where the flock had been. At same time, another Laf sang where I heard the Laf singing when I first saw flock.

It is fairly obvious that Lafs do not follow flocks over the borders of their own territories. 

[[left margin]] ? [[/left margin]] ADDITION: There was one burst of "song" from this flock, including a number of "Sreeeeeeeee"-type components which might just conceivably have been uttered by one of the diglossines. Unfortunately they were all pretty much hidden from view at the time

8:35 am. Come across what may be partial remnant of same mixed flock (see today's noted on subject). Including pair Rufs At first, they went uphill, possibly following Fire-bellies (at great distance). Silent. Then stop, feed in tree. Then one or both begin(s) to sing. All phrases essentially identical in basic structure. Series "Tuh-tuh-zeeee-a tuh-tuh zeee-a tuh-tuh-zeeee-a...." No. of phrases per burst of song quite variable. 4-8, I should say.

Then the pair turns about and flies down hill. One bird utters burst of song (4 phrases) in flight
