I just happened to notice this little fella while I was outside tonight. He was making a loud chirp and must have been looking for his mother. I think he may be a mockingbird as there have been quite a few in the garden lately and because of his markings. He let me get really close to him and didn't seem worried by me. I checked on him later and he had gone again.
@mimigd @snipsnap @sparkle @cath @pixels4u @dannydavies thanks everyone, he sure was a cute fluffy little thing but now he's gone hopefully with his folks so I wont see him again.
