I do have a peacock - well, a visiting one, anyway. He came to see me a short while ago when I was putting out the washing. (He loves sunflower hearts). Yes, he is noisy occasionally, but only at the time that he has his tail. His feathers will soon start falling out and then his voice goes - and doesn't come back until February when he starts growing his tail again.
For the first time for a couple of years we have seen a red squirrel in the garden - cue my making sure that the cat (even though he is now 14) is in.
Someone mentioned a sparrowhawk a little while ago. I was in the conservatory with my GS a couple of weeks ago and one swooped down and took a blue tit - very upsetting for us both.
This year I have had siskins in the garden for the first time for ages, too; everything seems to love the sunflower hearts - bullfinches, goldcrests, chaffinches, greenfinches, etc., and the blackbirds pick up the remains from underneath. One of my robins also tries to eat at the feeder - he's getting better at it!
