Game cameras to study animal behavior Part 1

Most of the time I use my game cameras to study animal behavior by giving the different animals tests so I can understand what would they do under certain situations. This test is to find out what a beaver would do when it comes across a big limb across its runway over a dam. Will it ignore the situation and just walk over it, move the limb, and if so what would it do with the limb? Would each beaver react in the same way?

Here's a picture of the setup where I placed the large limb across the trail or runway between two ponds.
