Reproductive Success of American Kestrels (\u3cem\u3eFalco sparverius\u3c/em\u3e) Nesting in Boxes along an Interstate in Northeastern Tennessee.

Nest box programs provide supplemental nest sites for American Kestrels, Falco sparverius. When the availability of nest sites is a limiting factor, the addition of nest boxes can increase local breeding populations. These programs also facilitate the collection of data on breeding kestrels. This study focuses on an American Kestrel (Falco sparverius) nest box trail along Interstate 26 in northeastern Tennessee during the breeding seasons of 1998, 1999, 2000, 2003, 2004, 2006, and 2009. Productivity measures and reproductive success of nesting birds are provided and compared to other programs. The data are analyzed across years and by box. Finally, a discussion of the habitat surrounding the most and least active boxes provides recommendations for increased efficiency of the program
