Though whitewinged doves consume a variety of native seeds such as doveweed (Croton setiger), leatherweed (Croton pottsii), and wild sunflower (Helianthus species; George et al., 1994), in San Antonio, large flocks of white-winged doves utilize neighboring agriculture fields to feed during the breeding season (West, 1993).

For this species we were able to test for differences in: (1)juveniles ([less than] 0.25 mm wide at setiger V), which had not developed tubes or with tubes restricted to the upper 2 cm of the sediment that were likely to be disturbed by wind-driven waves and (2) adults ([greater than] 0.5 mm wide at setiger V) whose tubes penetrate 5-10 cm into the sediment and form the adult tube mats found at the study site.
Diagnosis: The caruncle is small and hidden by the overlying peristomium and 7 pairs of branchiae are present first occurring on the second setiger. The short antennae and cirri are articulated and there are 2 pairs of eyespots with the second pair hidden under the overhanging peristomium.
