Still frozen 4?30
Ind. seems to be Frowning at us from time to time. Probably also has BT and/or MO, but difficult to tell at a distance

Finally moves to far side trunk 4:32. Again when we are obviously distracted (talking to one another)

4:36. Ind. utters t Trill's. Mouth open wide. Then starts to feed. Then he is apparently startled by us. Shoots down trunk head first. Disappears.

CORRECTION: This ind. probably left because another was approaching. In any case, the second ind. is on the tree a few seconds later. Feedingbusily without bothering much about us.

The first (shy) ind. had well marked flank stripes. The second (bold) ind. has no visible stripes. The striped ind. seen yesterday also was shy. And the non0striped ind. seen yesterday also was bold. I.E. there are persisten individual differences in disposition.

The second ind. ("II") gradually moves down trunk while feeding. Tail first by little stages.

Then first ind. ("I") comes back. Also feeds. Moving upward. I did not catch any display between the two inds. But they are never closer than 6" apart. Usually farther.

It looks as if there may be both individual distance and a well marked dominance hierarchy in this species.

After reaching bottom third of trunk, II starts upward again. 4:40 p.m. Still feeding. Then turns around and goes downward (head first) again.

It would appear that head first is used for fast and
