John, Are you using the Peterson styled nest boxes? I have found that House Sparrows don't favor them as much, since they have a more difficult time constructing their nests in those, since the box is tapered. They seem to favor the rectangular boxes. The other interesting observation is that I see many less sparrows and starlings around my property when I have Kestrels nesting but still get my bluebirds and tree swallows. Good luck.

It flew to a nearby log to feast. Later we found another pile of HSP feathers nearby. Along with 6 in the sparrow trap we aren't even making a dent in the population prior to Eastern Bluebird nesting time. The 4 pm Northern Cardinal show yesterday numbered 21 a record high for our PFW count and equalling our all time high.
