Know what you mean about furry things. Hopefully it's just squirrels, but if seeds aren't in a feeder they disappear FAR to fast.
I've noticed Coal tits (much nicer than Great tits don't you think) Blue tits, Robins and the usual Blackbirds, Sparrows, Wood Pigeons, Collared Doves and occasional Thrush. The best was a pair of Long Tailed Tits. They are very pretty. In the park the other day, I saw a pair of birds I can't identify. About as small as a wren, but they were crawling up the tree like mice. I assumed they would be tree creepers or nut hatches, but when I looked them up they most definitely weren't either. My mum suggested they were actually mice, but they did fly so I doubt it.
