It says Spring to me. And Spring is just outside my window. The old holly tree is a favourite of the birds, even though there is nothing left to eat there - they polished off all the berries by mid-November.
I suppose it's just a good place to catch the sun. I cant give you a link to Mandy's website because I found her on a gallery site that did'nt offer one. But Google her name - you'll probably find her.
