[[underlined]] Cebus capucinus [[/underlined]], Jun. 24, 1959, III

this [[underlined]] looks [[/underlined]] very much as if X had "learned" a ritualized pattern all her own!

There were also a lot of ordinary S Trll's uttered by 2 or 3 or all the animals when I let the three new ones in with the old. Not obviously animated with any helpful overt behavior. But twice, the young [[male symbol]] A very cautiously and slowly walked up to one of the new animals and stretched his head & neck forward til he almost touched the new animal with his nose, perhaps actually sniffing the new animal, and uttered several unusually loud Trll's each time it did so. A looked very "longing" as he did this, as if he very badly wanted to cuddle up to the new animal but was afraid to do so. This might suggest that the loud Trll's of this species are similar to those of all or some other species in being produced by frustration of some filial or gregarious motivation. The loud Trll's uttered by A in these circumstances were presumably the same as those I have called "T Trll's" and "L Trll's" in the preceding pages. Much louder than ordinary S Trll's, but otherwise quite similar in quality - [[underlined]] not [[/underlined]] deeper in pitch or wooden or hollow sounding. I shall continue to call them L Trll's.

A few of the animals did BT in the usual way in the usual circumstances. Always or usually silent.

All or most of the animals also uttered one or two brief moan-like notes from time to time Very difficult to interpret, as not obviously associated with any very particular type of overt [[un?]]ritualized behavior. Possibly just abbreviated MGB's; but it was my impression that they were more plaintive sounding than typical MGB's. Possibly a form of "M" ????

Sometimes, when one of the new animals would lunge at, or approach too closely to, A, he would jump back an inch or so and utter two or three brief notes very rapidly. Definitely "twittering" in effect. This may well have been a form of QTW; but the notes were quite pure and high
