This surprised me, House Sparrows here in the UK seem to get along with other small birds just fine, I never see any aggression at feeders or in the hedgerows.
Other thing is that in England, notably London, as well as in some continental European cities, house sparrows are now scarce where they used to be abundant, so if you live there you shouldn't be deterring them.
Might have something to do with house sparrows evolving there and it being their native range, so other animals have had time to learn how to deal with them.
