Tried Niger Seeds last year and the birds ignored them, and they don’t seem to like sunflower seeds in shells either, but they go mad for the sunflower hearts, and they’ve now started to go for fatballs and coconut shells filled with fat and seeds. In the garden I get a flock of Goldfinches, often numbering over twenty at a time, a small family of sparrows, some starlings, a couple of robins, blackbirds, chaffinches, Greenfinches, wagtails, occasionally some long-tailed tits, blue tits, great tits, redwings and fieldfares later in the winter, and I had a flock of waxwings last winter in the trees at the bottom of the garden. Had a sparrowhawk once some years back.
No baby robins tho’.
edit] I’d love to get a Jay and some bullfinches
