she sits on the ground and utters [[Trill's?]]. The, after a while, she may suddenly tilt her head backward, so that the chin and mouth point diagonally upward, and do silent PL toward me, looking "down her nose" straight into my face, [[underline]] just before going down into Hdd! [[/underline]] This can be provoked again & again if I keep moving my hand toward her. Each time she follows for a few seconds, uttering Trills as she does so, then stops dead, looks at me for a second with her head tilted upward and PL, either silent or with continuing [[Trill's?]], and then goes down into Hdd.
Such reactions would suggest that the PL is either lower intensity or more hostile than the [[Trill?]]. I think it is more hostile because of the following incidents. If I let the little animal grasp me, she settles down quite peacefully and quite silently for a while; but then she seems to become cramped & uncomfortable, and starts to readjust herself & move around. She shows a definite tendency to move upward at such times: She also usually utters a few [[Trill's?]] and does a lot of silent PL's, as usual looking straight up into the face of the person holding her when she does the PL's. This afternoon she behaved in this way when grasping Arleen; and this time she uttered a call which was definitely reminiscent, and obviously related to, the B of older animals as she looked up into Arleen's face with PL!!!
This B-type call was very interesting. Quite like the B of older animals, but softer & hoarser. A lot of notes uttered very rapidly one right after the other, almost running together. The individual notes were not much more separated than the "syllables" of a single [[Trill?]].  The whole call, the whole series of "B" Notes, in fact, sounded very much like a [[Trill?]] in which the "syllables" had become more clearly separated and more emphatic!! All this would suggest that the Trill and B patterns have barely begun to be segregated in this little animal!!!

Transcription Notes:
Hdd is abbreviation for 'huddle' Not sure about [[Trill]] could be Trll or Till - might be shorthand for Trill.
