Sparrows. Lots of them.
Blue, coal and great tits.
Robin sometimes has a go.
Quite a few lurk underneath for droppings - dunnock, collard dove, wood pigeon, jackdaw, blackbird
Then occasionally I'll see goldfinches once in a while.
I used to get greenfinches and bull finches, but I've not seen them for quite a while.
Now the nicer weather is on its way, I'll spend more time in the conservatory watching the birds.
Actually visiting the feeders I have Sparrows, Starlings, Goldfinches, Greenfinches, Robins, Collared Doves most days and according to season Blackcaps, Blue Tits, Great Tits, Common Redcaps, Chaffinches and Blackcaps. I also have all the usual ground feeding birds benefitting from what falls fro the feeders. I do get the very occasional visit from LTTs.
Ground and hanging seed feeders: sparrows, blackbirds, dunnocks, wood pigeons, collared doves, robins, goldfinches, blue and great tits, and chaffinches (at the moment).
