The large vine against the tree is poison ivy.
See the brown, hairy roots growing into the tree. This is a very old specimen, but a good picture of all that you might see in the woods in the winter, after the leaves have fallen off.
The vine across the front with the leaves is not poison ivy, but is more likely honeysuckle.
The front vine does not have leaves in the classic configuration, and these leaves are long and narrow.
