Q alone.

The animals also uttered a few single notes which were slightly different from the typical Q Notes.  Probably partly intermediate between Q Notes and one of the B-type notes.  I was struck by the fact that some of these intermediate notes sounded very much like the "chuck" Notes of [[underlined]] Callicebus [[/underlined]].

The Q and QTW performances we heard today almost all occurred during the first half of the period during which we watched the band.  Presumably when the animals were not used to us.  Stopped later on, presumably when the animals became conditioned

I heard a few Trll's (probably rather soft) uttered even during the first half of our observations.  Apparently uttered only by young & immature animals (which uttered few or no Q's or QTW's).

During the last part of our observations we heard only Trll's and MGB's.  I am not sure why we heard so many of these at that time.  Possibly because by that time we were watching a part of the group which was made up of immatures alone or immatures with only a few scattered adults among them.  In any case, it was interesting that during this period none of the animals uttered Q's or QTW's or rushed at us in a particularly aggressive way.  The only aggressive patterns at this time were BT, which was still quite common, and some Jud, which was less common and usually not very vigorous on the whole.  This would suggest that both the BT and the Jud are lower intensity and/or less aggressive patterns than the Q and QTW.

Several animals uttered single "sneezes" during the period when Q and QTW were particularly common.  I did not hear any more sneezes after the Q and QTW, which might suggest that the sneezes were display of some sort; but unfortunately I was never able to see the animals which were sneezing.
