rather than young. (Robin Foster agrees with me about this. He also says that the understory shrubbery here is so much more diverse than in BCI And he suggests that may trees are small and thin here because epiphytes are particularly numerous. Large spreading trees might tend to topple under the dead weight of their commensals. And it is true that we have heard two enormous tree falls in the short time that we have been here.)

1:10 p.m. Come across group of 6 tamarins at a time when the rain is particularly heavy. Animals absolutely soaked. This is the first time I have seen Amazonian tamarins in real rain. Two individuals sitting out in open 30 ft up, feeding on plum sized soft greenish-pink fruits. Others clinging vertically to tree trunks, 20-40 ft up. Motionless, except for shaking head to flick off rain from time to time. This vertical clinging seems to be a reaction to the rain, an attempt to get as much shelter as possible. 

As far as I can tell, group is [[?]]. One vid, is quite young, perhaps less than half grown. 

All the vids seem quite "distracted" by the rain. Apparently pay no attention to us, at first, even though we are in full sight 100 yards away. We watch them for about 10 minutes. Then move closer. At which point the animals finally move off. Running and leaping horizontally. Beginning to vocalize at same time. Lots of LSN's. Some other alarm calls. Disappear very quickly.
