Understanding how land cover and potential competition with invasive species shape patterns of occupancy, extirpation, and colonization of native species across a landscape can help target management for declining native populations. Mourning dove (Zenaida macroura) populations have declined throughout the United States from 1965–2015. The expansion of the Eurasian collared‐dove (Streptopelia decaocto), an introduced species with similar food preferences, may further threaten mourning dove populations. We analyzed data from 2009–2016 from a large‐scale monitoring program in the Western Great Plains of the United States in a 2‐species occupancy model to assess the effects of collared‐doves on mourning dove distributions, while accounting for imperfect detection and variation in land cover across the landscape. Mourning dove occupancy was stable or increasing across our study area, and despite overlap in resource use and co‐occurrence between mourning doves and Eurasian collared‐doves, we found no evidence that collared‐doves are extirpating mourning doves from preferred habitat during the breeding season.
