Now's the time to set up your American Kestrel nest box! This bird's population is experiencing long-term declines in North America, and existing data are insufficient for understanding the causes. The American Kestrel Partnership is an international research network designed to generate data, models, and conservation plans for kestrel habitat and populations at large spatial scales. The Partnership unites the data-generating capacity of citizen scientists with the data-analysis expertise of professional scientists by promoting research collaboration among citizen scientists, universities, government agencies, conservation organizations, schools, and businesses. The Partnership also fosters long-term conservation values and appreciation of science by engaging the public with hands-on research experiences.
