Launched 2012 in response to long-term population declines of kestrels in North America, The Peregrine Fund’s American Kestrel Partnership is a network of citizen and professional scientists working to collaboratively understand kestrel demographics and advance kestrel conservation.

The American Kestrel Partnership is made possible with support from these generous donors:

Michele and Agnese Cestone Foundation, Coypu Foundation, Honoring the Memory of Molly Dudlak, Felburn Foundation, The Kemmerer Family Foundation, Judith King, Jane Smith Turner Foundation, Lynn and Jack Loacker and Deida Runswick (Kemmerer Foundation).

We also greatly appreciate the numerous supporting organizations that sponsor this project.

Population Decline

Data collected from ongoing research studies indicate long-term declines of American Kestrel populations in numerous regions of North America. Unknown cause have contributed to an average decline of 50% across the continent since the 1960's. Learn more about the history of American Kestral population declines.


Kestrel Research

Research Goals - The American Kestrel Partnership is developing and coordinating a network of locally managed nestbox monitoring programs across North and South America to generate kestrel nesting data at unprecedented scales. Click here to learn more.

Our Publications - Understanding a more complete picture of the American Kestrel’s life history is an integral part of conserving kestrel habitat and populations. To read more about the science behind American Kestrel conservation, click here.

Additional Research - Learn more about American Kestrel biology and delve into the studies of scientists working to conserve the American kestrel.


Become a Citizen Scientist

The American Kestrel Partnership consists of more than 600 partners - citizen scientists, contributors and volunteers. Data recording is actively occuring for more than 1,400 kestrel nests, from Alaska to Argentina. Interested in learning more about installing and monitoring kestrel nestboxes? Data collection is vital to our kestrel conservation efforts. Visit this tutorial to learn more and join today.



Want to contribute but installing a nestbox not an option? No problem. View Kestrels live during the nesting season and log what you see!

The Full Cycle Phenology Project brings together a group of diverse and uniquely qualified collaborators from Boise State University, the American Kestrel Partnership, HawkWatch International, St. Mary’s University, Environmental Laboratory of the U.S. Army Engineer Research and Development Center, and the University of California, Los Angeles. This project will combine cutting edge genetic techniques and a large-scale collaboration of professional and citizen scientists across the western hemisphere to find out more about migratory connectivity, population change, and the impacts of climate change on the American Kestrel and other migratory birds.


We are currently collecting feather samples across the breeding range of the American kestrel for genetic analysis. Visit the Full Cycle Phenology website to get involved.
