Observations of the nest boxes indicate that every box at Nauvoo was used as an active nesting box. I was somewhat surprised to see most of the boxes were packed with "stick nests" indicating wrens as the primary user of the boxes.
Grandvue boxes were more sparcely utilized and predators seemed to be the primary obstacle. I did however have successful nests with bluebirds, wrens, and tree swallows.
Plans this year include a large box for common meganzers on Fish Creek.
