In Kansas, burrowing owls are uncommon summer residents in western shortgrass and mixed-grass prairies where prairie dogs have not been extirpated (west of the 100[degrees] meridian; Busby and Zimmerman, 2001; Klute et al., 2003), and it appears they have never been common in eastern tallgrass prairies (Sheffield, 1997; Klute et al., 2003).
