However, they sometimes accept cowbird eggs and have been documented raising bronzed cowbird fledglings in 5-8% of active nests in the LRGV (Hathcock and Brush, 2004; Werner et al.
Because of the high concentration of wetlands along the Rio Grande and the extensive habitat fragmentation in the LRGV, we hypothesized that (1) the linear density of individuals is greatest nearer the river, (2) gene flow caused by dispersal of individuals is reduced, and (3) the population dynamics of the species could best be described by a metapopulation model.
As of 1990, more breeding white-winged doves occurred outside the LRGV than within it (George et al.

Habitat degradation in the LRGV (Curtis and Ripley 1975; Lonard and Judd 1985, 1991; Brush and Cantu 1998) coupled with anthropogenic landscape scale changes increasing habitat suitability north of the LRGV may be facilitating this change in White-winged Dove distribution (Kiel and Harris 1956, Cottam and Trefethen 1968, West et al.
