American Kestrel Nest Box Project

Our American Kestrel Project is headed into its 9th season! This project was started in 2015 by Frank and Kate Nicoletti, as a way to support this declining raptor by providing nest boxes in a landscape that has few natural opportunities for nesting, but lots of good habitat. A crew of nearly a dozen volunteers monitor 52 kestrel boxes in the Greater Sax-Zim Bog Ecosystem and submit data to the Cornell Lab of Ornithology’s NestWatch Portal. Learn more about NestWatch here.

At the end of each season, a report of how the year went is shared on our BogBlog. Below are links to each summary.

Additionally, collected data will be used to publish nesting data on American Kestrels in our area and has been used in a few projects to better understand environmental contaminants, diet and prey composition, and local productivity of American Kestrels. Data gained from Sax-Zim Bog-nesting American Kestrels fitted with transmitters from a partnership with the Minnesota DNR, was recently published and can be found below.
