This greenfinch was looking very serious when I took this but I think he was concentrating on the sunflower hearts. He actually has one about to drop away from his beak. All the birds seem to love them and I have had goldfinches, chaffinches, blue tits, great tits,coal tits, great spotted woodpeckers and of course blackbirds and starlings. There seems to be a lot of young birds which is nice to see.
