I feed
the 'RSPB hi-energy no mess' mix from CJ Wildbird; it's probably more
expensive than the one you're using, but it is also much more suitable
for the smaller wild birds such as tits, greenfinch, goldfinch and of
course sparrows. So I'd suggest changing the seed (if you can bear the
cost).

Same here but I buy it in large sacks and get through one a month
because so many blinking doves and pigeons come along about 5 to eat the
seed! I put up one of those cages that fit round a feeder to stop all
but the large birds getting the seed but only the blue tits and
greenfinches will go through the bars. I left the other six feeders
alone so at least the sparrows get some food.
