Wren’s Nest
A twitch of moss
in the drystone’s battered face
hint of fidget
in a soft-mouthed cave
a sudden squirt
from an inch-wide perfect circle
sooty brown
like stumbling on a puff-ball.
Particles of wren
too quick to count, too many
plump as chocolate truffles
insubstantial as fritillaries
diffusing: burrs on thistle mast
fluff in the bramble mattress.
