summer haiku and tanka

I.
the full moon flutters
on the surface of the pond
dancing in time to
the first song of summer sung
by a lonely cicada

II.
the summer moon bursts
from behind the clouds – startled
an owl takes flight

III.
still summer air weighs
heavy against the trees and
then the rain begins

IV.
small bell sounds like rain
in the summer dawn – birds sing
to the cobalt sky
