Bluebirds of Perrot

13 nest boxes in Perrot

As you wander throughout the park, you may come across birdhouses situated on a post. These are Eastern Bluebird nesting boxes provided by Brice Prairie Conservation Organization. There are currently 13 of them being monitored. Last year these nest boxes produced 73 Bluebirds along with 11 Tree Swallows, 8 Black Capped Chickadees and 12 House Wrens.



3 and 1 more to come

The female Bluebird builds a nest inside the nest box consisting of grasses and pin needles. In about a week or two, 3-5 eggs are laid. The eggs hatch in about 10-14 days. The chicks are cared for and fed by both parents. After 16-23 days, the chicks are ready to fledge.

Notice how clean they keep their nests.

Bluebirds typically have two to three nests per season. The biggest obstacles to Bluebirds reproduction are weather, predators, and competition among other cavity nesting birds.

"Four Calling Birds"

According to the Bluebird Restoration Association of Wisconsin, over 35,500 Bluebirds fledged from 9334 monitored nest boxes across Wisconsin. As of this August, the fledging count is as follows: 67 Bluebirds, 9 Tree Swallows and 5 Wrens.

Steve has been monitoring the Bluebird population in the park for the past two years.

Thanks Steve for sharing your photos of these beautiful bluebirds. Hopefully we will have three nests this season.
