I have seen Chinta climbing the tree near the viewing area that is between the Gorilla and Orangs.,whilst Bulu sat at the very end of the large island whilst Gambira just chilled inside.
I think the only way to get a picture of the area the orangs have is to wait untill the leaves are of the trees and go up the bank over looking the enclosure. Climbed up there yesterday for a recay but too many leaves blocking the view. Might need a reminder as winter approaches.
I think these trees have looked like this for some time. Demo has been stripping bark off trees on both islands lately, something Nakal used to do to the lower parts of these Alders.
Bark stripping could spell damage to the trees longterm- possibly more than branch breaking. However the foliage/tree growth is sufficiently dense that maybe the orangs can't do any real damage- only time will tell.
I saw some mature Alder trees the other day and they were exactly the same shape- very tall with no branches until you reach the crown- so I think the tree that Chinta is on here hasn't been altered very much by the attention of the Orangutans. Smaller Alder trees have a more typical 'tree' profile with lots of branches.
