I gave up on peanuts a long time ago as they ended up going mouldy, but fat balls and fat blocks are popular - the long-tailed tits really like the blocks and they're big enough for several to feed at once.
And there is a tray of mixed seeds and mealworms, which are popular with blackbirds, robins, dunnocks, blue and great tits – and the sparrows eat anything there, they're not too fussy.
