9:20 am.  Hear what sounds like saki L Trill's in distance.  But there aren't supposed to be any sakis in this forest!

COMMENT:  A thought has just occurred to me.  I know why Saimiri are the nexus of "friendly" interspecific relations.  Unlike all other Platyrrhini, Saimiri never try to escape predators by freezing, remaining quiet and motionless.  Or at least do so only very rarely.  They rely upon seeing predators and actively avoiding them.  Thus they will always welcome additional eyes.  And they don't care if the additions make the group more conspicuous.  (And the fact that they are so abundant indicates that they can cope successfully with almost any form of competition.)

Are Cebus spp. more nearly similar to Saimiri in this respect than are most other N.W. primates?

9:30. Same area where L Trll's heard earlier.  Hear more.
Light sprinkles rain star 10:30 am.  Continue off and on.  I wander around without seeing any trace of monkeys.

NOTE:  There are lots of jays (Cyanocorax type) around.  As well as some toucans.  There must be lots of competition for food.

Finally starts to clear up 1:00 pm. Blue sky.

Then, 1:30, hear unmistakable Callicebus.  Rather different from moloch.  Obviously tarquatus.  But animals invisible.  Song quite long.  Apparently several phrases in succession, run together [[image: single wavey line). And all Song apparently louder, probably slightly deeper in pitch, possibly slightly slower than Resonating Notes of moloch.  General effect
