Bats

Only the bat is nebular
Their streaming shadows play the remaking of a light show; 
Serotine ,
Pippestrelle or Horseshoe
Forms identified by ear or fur
Personified in mystery in
Soft bodied perpetual motion 
With a fleeting glimpse
A powdered spectre;
Flight 
At dawn or dusk.
Yet through the night
The shadows play against the glass
In liminal motion
Retreating and oscillating
Back and forth
A mesmerising display
If I should stay awake to see.

We have always had bats in the roof. Last year they moved around to just above our window , most probably a nursery roost .They are here again this July . There are more than ten of them and are beautiful to watch as they fly before nightfall.

One came in the other night through the window.
