These White-faces did not appear to be very greatly frightened, even when they first discovered us (they ran into us, rather than us running into them). Quite irritated. Most of the animals which were on the ground ran part way up trees when the band first reacted to us; but quite a number of animals either stayed quite low, or returned to the ground, or never did leave the ground; and many of these "low" animals displayed at us vigorously.

The most common display of all the monkeys, in the trees or on the ground, throughout the period we watched the band, was BT. Usually silent. It seemed that no monkey could look at us without doing BT. It is obvious that the [[bighest?]] intensity forms of BT are those with the lips drawn furthest back at the sides. This type of BT is apt to be accompanied by vigorous "Jud-ing" (see below) and occurs in close association with Q and related calls; while BT without the mouth drawn back at the corners (mouth just open like a goldfish) is usually performed by animals who don't do other displays and seem to be very little excited in general.

The next most common "display" was the usual straight-legged jumping up-and-down. I shall call this "Jud" from now on. This was performed by [[birds?]] on the ground, who couldn't break off branches as well as by [[birds?]] in the trees. Almost always accompanied by BT, and frequently combined with Quad related noises, (see below).

The most common calls were single Q notes. These seemed to be essentially the same as those I have hears uttered by captive animals. I was particularly struck by their resemblance to the Q notes of the Puiche's in actual sound. Just a little deeper, a little less sharp, and perhaps a little more irregular.

The Q notes were usually uttered singly, or perhaps in series of 2 or 3 notes with definite pauses of considerable, if irregular, length betw

Transcription Notes:
I think bighest was meant to be highest.
