South Pacific Islands-Crash Site secret No. 2

[P.Balshaw]

Does anybody know where secret No.2 is in the south pacific islands, crash site is. Where there is a pool of piranha fish. You climb a tree, shoot a raptor dinosuar then shoot a rope with another raptor tied to it and it falls into the water and somewhere in the branches of the tree that you are in there is a secret, but I can`t find it. Can anybody help?

The secret is a green "Gem"!

You get access to it by first jumping to a ledge to the left, at the back of the tree. On the ledge you turn right and jump to pull up to the higher branch. You will see it imediately once you are on top.
