WE have about 16 nest boxes on poles around our field. Initially they were
for bluebirds, and then the tree swallows arrived. Our strategy: the nest
boxes are erected in pairs: one for the bluebirds, one for the tree
swallows. House sparrows may move into one box in a pair, but not both.
Good answer Bill. Thanks for sharing this equitable solution.
