I, Upside Down

am elusive in leafy roofed
big, mature, stout, oaks,
hornbeam, beeches.

I make caves,
plaster mud or dung
round nest holes.

Happiest when hung
in a reversed world
headfirst walk down bark.
Tree roots and greengrass sky,
blue, cloud roamed ground.

A different perspective.
A world reversed.
Seen from ground up.
