I also have the advantage of being able to see the wildlife at all levels. Ground level has opossums, worms, lizards, turtles, salamanders, foxes, deer, roadrunners, snakes & rabbits.
Mid level of low branches and tall shrubs have small birds, praying mantis, lady bugs & butterflies.
Tree tops are larger song birds, squirrels, hawks, crows.
There is always something to watch from the tree house.
