The tatapiririca tree, sap

As noted in the previous post, the silvery marmosets chew holes into the bark of the tatapiririca to sup up the sap. They also eat the resin, which forms from the same. I found this mass of coagulating sap under one of the trees next to the Bosque reception center, and there was much more on the ground. I would guess that maybe it flows in greater concentrations in the upper part of the tree. I suspect that that's the case, but I don't know for sure.
