Feeders: Hang 'em high?

Just a quick hanger query. I have a hanger pole for 3 feeders and it's lost a foot in height due to having to firmly entrench it so one of the feeders is about a foot from the ground. Will this deter any birds who may only feed from high up? I regularly get sparrows (lots!), great & blue tits, goldfinches, starlings, blackbirds and the odd linnet. Robins too, but they use the table feeder.
