Shooing hangar sparrows

They don't nest but
occasionally poop, being birds after all.


Any suggestions on how to humanely repel / discourage these birds?

One of the local banks had a bird problem at their covered drive
through. I think the convertible drivers probably complained the
most................

Their solution - that seems to work - was to cover the bottom of the
roof structure with what we call "chicken wire". It's an inexpensive
fencing material made of light gauge wire woven into an octagonal
pattern.

The birds still fly through, but can't land.
