Effects of supplemental prey, vegetation, and time on success of artificial nests

Article Abstract:

Low-nest survival rates are linked to predators, though other factors are important, such as habitat and prey resources. Artifical nests on Conservation Reserve Program sites in Texas have been studied to assess the impact of prey supplementation, time, and vegetation density on nest survival. Prey supplementation had the biggest impact, though available nesting cover is also important, as is shown by the greater success of earlier nesting. The economic and logistical costs of prey supplementation should be assessed, as well as the impact of populations of predators.

Influence of vehicular traffic on time budgets of nesting burrowing owls

Article Abstract:

A study of the time budgets of nesting burrowing owls (Speotyto cunicularia) in Rocky Mountain Arsenal (RMA), Colorado, reveals that vehicular disturbance has negligible influence on the behavior and productivity of the owls. The resting time, alert and out-of-sight behaviors in the pre-hatch season differs in the male and the female. Alert behavior increases and out-of-sight behavior decreases in the female from pre to post-hatch seasons. The time spent out-of-sight increases and alert behavior decreases in the male.

Reproductive responses of adult female northern bobwhite and scaled quail to nutritional stress

Article Abstract:

Breeding scaled quail and northern bobwhite undergoing food deprivation experience nutritional deficiency which affect their reproductive activity. Energy deficient diets lead to feeding compensation while protein deficient diets does not. Nutritional stress, specifically protein deficiency, greatly affect the reproductive activity of both species. However, scaled quail show lesser adverse effect which means these have lower nutritional requirement. These imply different reproductive ecology.
