[[circled]] 22 [[/circled]] [[underlined]] Cebus capucinus [[/underlined]], Jun. 13, 1959, IV. [[3 straight and 1 scribbled line run down the left margin]] -erlooked in this species. Quite reminiscent of [[underlined]] C. apella [[/underlined]] in actual sound. One or a few notes. Quite variable. Most could be translated more or less as "Wheeooo." In the case of E today, however, it was obvious that the WB is only an imperfectly regulated [[underlined]] intermediate between typical Wstl's and typical MGB's [[/underlined]]!! Seemed to intergrade with both the latter notes to a quite appreciable extent. A few WB's were a little quavering [[wavy line]] It was my impression that these WB's were mildly hostile and/or provoked by some thwarted gregarious or infantile motivation. Centering [[underlined]] not [[/underlined]] usually accompanied by obvious overt attack or escape intention movements. All or most of the WB Notes of E today were accompanied by some slight PL Very slight with mouth open only very slightly. The WB's were certainly the most common of the B Notes uttered by E today. Again reminiscent of [[underlined]] apella [[/underlined]]. The next most common of the B Notes were MGB's. Sounded just like the ones I have heard [[may?]] animals utter before. Usually or always accompanied by a moderate amount of PL, with mouth moderately open. There appeared to be just high intensity WB's - in some sense at least. Probably just more strongly hostile. Attack & escape probably nearly evenly balanced. Seldom or never accompanied by much in the way of overt attack or escape movements. Both the AlB and BB Notes were much rarer. Again sounded just like the notes I have heard previously - and occurred in very similar circumstances. The BB is obviously more aggressive (and higher intensity???) than the MGB. Usually or always accompanied by a slight trace of Jud. The AlB is at least something of an alarm note. Less aggressive (and higher intensity???) than the MGB E tended to give a series of AlB Notes when he saw someone new and unfamiliar approaching in the distance. I think that E's AlB's notes were accompanied by the same type of PL
