Camera traps are hard to run in the trees.

First of all, you have to get them up there.  Most tropical trees have a long trunk with no branches for the first 10m, so you need to get a rope up on a sturdy branch and climb that (we prefer the giant-slingshot method).

Next problem, trees sway and blow in the wind.  This can trigger the camera trap, filling your memory card up with moving vegetation but no animals.

But there is at least as much action up in the rainforest canopy as down on the ground, so we need to start aming our cameras upwards to get the full picture.  Vivian Maas took on this challenge, focusing on fruiting palm trees.  She scoured the forest to find fruiting trees with another tree nearby that could host the camera, then got some climbing help, and crossed her fingers.

The inital returns were dissapointing – no animal action.  It seems we were a bit early and the fruit wasn’t ripe yet.  Once it did ripen, Vivian captured a variety of frugivores incluing monkeys, opossums, parrots, and my favorite – the kinkajou.

Here is a troop of howler monkeys in a spiny-palm that is just loaded down with fruit.

Finally, a few trouble-making capuchins that bump the camera a few times.
