Here is Auntie, with the picture
zoomed out. Note the "rabbit trail" mainly to Auntie's left that has
been cut from the twigs and branches of the surrounding brush. Auntie and her
companions cut the trail themselves. Cottontail rabbits don't build their
warrens by burrowing like European rabbits do but instead, live in heavy brush
that they modify for their use.
