don't see them well. (Trying to record as usual.) But guide says that group included approximately 30 Saimiri and 8 Cebus apella. All fled almost immediately. C. apella in lead. 

  All I heard was one single "MGB" note. Couldn't tell by which species. In general, animals not vocalizing while feeding.

  All the movements I saw were ca. 30 ft up. In mixed second growth area.

  Guides say that associations between Saimiri and C. appella are common.

  They also say that the appela pound on wood relatively frequently. Presumably extracting grubs like capucinns.

  9:45. A few hundred yards further on. Same type of forest. See pair fuscicollis 20-30 ft up. Give a few alarm notes [[left margin]] 7 [[/left margin]] (which I can't record) and then flee. These animals certainly were not associated with the Saimiri and the apella.

  10:05. Another few hundred yards further on. Come across mixed group of Saimiri and Cebus apella. Presumably same group seen earlier. Again movements very noisy. But this time there also were vocalizations. Lots of Lost Calls by the apella. Very reminiscent of "Joah" notes of capucinns, but typically uttered in longer series. Also more plaintive in tone. I got several recordings of these (plus some beautiful imitations by guide). The apella also uttered a few barks. AlB's and/or MOB's. I think that I missed these on the tape. The Saimiri also uttered alarm notes. Sharp, rather sneeze-type sounds, sometimes getting thinner and higher, almost purely "Tsit" like.
