Habitat loss and fragmentation since the 1920s have been implicated in the decline of white-winged dove (Zenaida asiatica, WWD) populations in the Lower Rio Grande Valley of Texas. Although recent land acquisition and reforestation have increased habitat, a decline of this economically important game bird still exists. Therefore, 7 major land use components across 20 sites were assessed to determine whether land use availability and fragmentation were related to WWD density. Aerial photograph interpretation was used to delineate land use components in 1961, 1983, and 2002. Additionally, vegetation in 15 nesting colonies was sampled in 2002 and 2003 to examine relationships between WWD productivity and microhabitat variables. Results indicated very few statistically significant relationships between WWD density and land-use change or composition. Furthermore, WWD prefer dense overstory canopy and fairly clear understory cover for nesting habitat selection and nest success, particularly those brushlands dominated by Texas ebony ( Pithecellobium ebano).
