I've always been fascinated by owls.
They are so rarely seen and I hear them almost as infrequently these days, yet their call is so instantly recognisable, almost magical and haunting.
I also like this old rhyme (unknown author)...
A wise old owl lived in an oak
The more he saw the less he spoke
The less he spoke the more he heard.
Why can't we all be like that wise old bird?
