Not garden visitors, but as I was stuck in a Plymouth car park for a while, with Daughter, waiting for a recovery truck, her car had a flat tyre, there is no spare on an S Max:-C
I thought I'd see what was about. I was amazed, there in the heart of Plymouth, in the trees bordering the car park, I saw a flock of mixed Goldcrests & Long Tailed Tits, calling to each other as they flitted from tree to tree, a Robin, a Blackbird, several Sparrows, many feral Pigeons, Herring & Black Headed Gulls. One of the former landed on the roof of a stopped bus, it's panic as the bus pulled away, was amusing to watch.
I am usually too busy shopping to bird watch & I didn't realise there would be so many.
