night mover
... I type through the early hours in an otherwise silent conservatory by the glow of an anglepoise lamp, sipping a glass of cold, lactose-free, semi-skimmed and wondering just why owls - who are remarkably well-equipped to hunt at night - ever developed their unique physiology in the first place. Why become nocturnal? Was it because they couldn't sleep? Did they say 'Fuck it guys, you know what? We'll embrace the dark and stay awake all night!'? I'd like to think so.đŸ˜‰Their specialised adaptation as night movers and hunters includes their ability to fly silently, and to see and hear in the dark with exceptional acuity; (that's my word of the week).
Their feathers act not only as camouflage, they are also covered with a soft, velvet-like structure that dampens sound. Their wings are large, meaning they can glide and don't have to flap very often, plus they have baffles along the leading edge of the wings that breaks up the turbulence which is the major component of noisy flight. Their prey simply cannot hear them coming.
They locate their victims first by sound. Unlike human beings with our symmetrical ears and stereophonic hearing, owls have ears that are located asymmetrically in their skulls and thus they can locate sounds in three dimensions, not just two. This affords them pin-point accuracy when detecting the position of a target mouse or vole, even in complete darkness.
But their night vision is also extraordinary. Their enormous eyes are specialised to collect what little light there may be. Those eyes are so large in fact that they have lost the muscles that normally allow eyes to move around in their sockets, which means they must turn their heads if they want to vary their field of vision. As a result, they've had to developed the ability to swivel their heads about 270 degrees in either direction (compared to our 90 degrees left or right).
Finally, as with cats' eyes, they have a tapetum lucidum behind each eye, a reflective surface that bounces light back to the photosensitive cells, allowing them a second take to detect differences in light even at very low luminance. Wow, owls...
... though of course there are other predominantly nocturnal animals, quite a list - in fact well over a hundred creatures who prefer the hours of darkness to the day. They include the black rhino, cockroach, dwarf crocodile, great gray slug, honey badger, nightingale, paradoxical frog, raccoon, sugar glider and woolly lemur. But I'm not concerned with any of them. I'm only thinking about the owls...

...and wallpaper (see Snowy above, £63 per roll - not found in the house on the strand, I hasten to add); and cranking up the Saturday night imaginarium to devise this flight of fantasy, a sort of baffled nocturne, to fit:Owl PaperSince I let your shape escape in pricking night,I shouldn't be shocked if the ghost of a screechteases my disoriented ears, or the merest sense of a velvet swoop nearly makes me duck down.
Owl paper, over cracks where darkness seeps in,decks these bedroom walls and although I knowthat in this eery stillness of nocturnal pitchblendethe only thing really moving is my mind, I howl.
So I turn on the light. You are branched as beforein your oak tree, beaky, big-eyed and swivellingto regard me curiously, with just a hint of distain.But how to explain a scatter of pellets on the floor?
To close out on theme, here's a musical bonus from Principal Edward's Magic Theatre, a band I was very fond of in my teens, so much so that we engaged them to play a charity May Day gig at my school when I was in the sixth form. This song comes from their debut LP. Just click on the title to play it: Enigmatic Insomniac Machine
