There are several different methods
Fishing line is the easiest
Avoid platform feeders !
Sparrows don’t like short perches
I cut the perches on my finch feeder to about 1 1/4″ and tied some fishing line around top-keeps 99% of them away
You can use wire coat hangers or pipe cleaners-anything that obstructs their flight path to the feeders
A “clingers only ” feeder is very effective as well
Sialis.org has all the info
Good Luck
