Hear a number of Whistles. Probably 9 notes in 3 triplets. All this sounds rather LW-like. And Aristides says that they are uttered by fuscicollis. But nothing follows them.

We spend considerable time trying to track these animals down. Without success. Hear a few more series of Whistles. One doublet, one triplet, and one quadruplet. Very slightly plaintive, but much less so than LW of geoffroyi.

Then, 3:45, find small group of fuscicollis. In region of half cut down forest, with only a few trees left standing. Apparently 3 tamarins in group. Quite dispersed. Moving 15-35 ft. up. Utter a few LSN's and trills when they see us. Np Whistles. Move off rapidly. Some Indrisoid leaps. Also some very long squirrel-like leaps. 

Thus it seems possible that fuscicollis may have a "precursor", or relact, of an LW pattern. But it is very poorly differentiated. And quite possibly or probably purely hostile. 

(In actual fact, I couldn't be sure that the animals just seen were not engaged in a boundary dispute.) 

4:10pm. Region of very mixed forest. Catch glimpse of Saki high in far distant tree. Try to track it down. But it stays hidden and quiet for some minutes. Finally we manage to flush it from tree 40 ft up. It utters alternate Roars and Low Trills. Then moves off and sits (hidden) in distant tree, uttering L Trills almost constantly. Then we flush a second Saki from another tree 30-40 ft away. Also ca 40-50 ft up. It also utters alternate Roars and L
