Kestrel nestboxes are busy places this time of year. Because kestrels’ nesting habitat (tree snags) has all but vanished in their range, and because they take readily to man-made and managed nestboxes, our dedicated group of Kestrel Nest Box Program volunteers are also busy this time of year checking out what’s happening in the nests!

To aid in their efforts, Madison Audubon volunteer Pat Ready created a “Guide to Kestrel Box Species” which helps monitors determine who is using the nest (because it’s not always kestrels!), and what to do about it.
