Kestrel Nest Box Monitoring & Banding (2026)

American Kestrels, North America’s smallest falcon, have faced a population decline of over 60% in the last 60 years. With an increased removal of nesting habitat came an increased need for them to rely on provided housing like nest boxes.

American Kestrel: 2025 nest box and banding report

In spring and summer, over a hundred volunteers give their time, energy, gas money, and hearts to American Kestrels. Why? Because this species is beautiful, fierce, and in decline; and the focal point of our citizen science program the Kestrel Nest Box Monitoring & Banding Program (KNB for short). Each year, hundreds of kestrel chicks fledge from the boxes these volunteers steward, and those chicks and some of the adults are banded for research. And each year, we try to get creative about how we can continue to make it easier for kestrels to successfully raise their young in southern Wisconsin.

Usually, our monitors go out on a nice day in February to double check their nest boxes to ensure they are ready to go for mating season at the end of March. However, 2022 started much differently.
