Tyto
alba
Caspar has been with us at Exmoor Falconry since 2003. Like all
owls he has been hand reared, so he is content to be around the
public. For the first few years he was flying in the outside display,
but this winter (2008/2009) we have retrained him to fly in our
indoor Owl Show in the medieval barn. He is an absolute star.
Always on the go, post to post, quartering the ground, and circling
to pounce on the pounce boxes, he has to be one of our most active,
and fun birds here.
Barn
owls are well documented and one of the best know species, found
throughout the world except the cold Arctic north and Antarctica.
They
feed mainly on short tailed voles, especially at breeding time,
and may have 4-6 young tucked away in a safe nest in a barn or
building. They hunt by quartering the ground, or riding fence
posts along a field edge, their long wings designed for open field
flight, often with shallow wingbeats rather like a butterfly!
Beautiful birds to watch.
They
depend largely on their hearing in hunting and may hear a vole
within the roots of the grass up to 200m away. When not hunting,
a flap of skin, called an operculum, closes to keep out the sound!
We
have barn owls visiting our farm, occasionally in the trees around
the walled garden, and now and again in the barn itself. They
are reasonably common around Exmoor, and have even been recorded
nesting over Exford, at an altitude of 1200ft. Our small tussocky
fields with plenty of hedgerow and rivers is ideal for them, with
plenty of old buildings to nest in, and a good population of voles.
