Effects of a Supplemental Food Source and Nest Density on Success of Artificial Ground Nests
Nest predation can limit avian recruitment and may be a proximate source of population declines in many avian populations. Because nest predation may be affected by availability of alternative foods and nest density, we used artificial nests and track counts to evaluate effects of supplemental food and nest density on nest success of artificial ground nests. Nest success was lower at 7 of 9 nest density classes when a supplemental food source was present. In the absence of supplemental food, nest success was inversely related to nest density, but when supplemental food was present,...
