[cayugabirds-l] bluebirds vs house sparrows

2015-03-25 Thread Bill Mcaneny
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.
