Factors affecting white-winged, white-tipped, and mourning dove reproduction in Lower Rio Grande Valley
Article Abstract:
It seems that nest predation by great-tailed grackles does not restrict productivity of white-winged, white-tipped or mourning doves. This research, undertaken in the Lower Rio Grande Valley of southern Texas, found that woodlots dominated by Texas ebony and Texas sugarberry were significant nesting habitats for all three dove species. Mourning doves seemed least selective of the three dove species with regard to nesting habitat. There was no connection between the abundance of grain fields and dove productivity, indicating that food availability does not restrict dove productivity.

Bioenergetics of white-winged dove reproduction in the lower Rio Grande Valley of Texas
Article Abstract:
A study has been conducted to determine whether the availability of food affects productivity in eastern white-winged doves, Zenaida asiatica asiatica, in the Lower Rio Grande Valley of Texas. Results showed no correlation between productivity and the availability of energy or protein in the diet. There were also no differences in the body composition of doves in the various nesting stages. However, lipid masses peaked at hatching and was lowest at prenesting, suggesting that doves have a mechanism for maintaining a positive energy balance. These results suggest that doves consume high-energy foods when available to improve and maintain their condition.

Changes in white-winged dove reproduction in southern Texas, 1954-93
Article Abstract:
Several factors have been identified to have caused changes in the white-winged dove reproduction in Lower Rio Grande Valley of Texas. However, there was also a need to identify the factors that limit the reproduction of the birds. Historical data show long-term decline in productivity which suggest variables that include egg density, fledgling success and both density and success. Availability of food was shown not to greatly impact on the productivity. What had been strongly indicated is that harvest exceeded breeding population levels.
