Mechanisms underlying nest predation and thus influencing songbird fitness are poorly understood. We used differences between natural and experimental nests to examine the influence of parents on nest predation rates and patterns. We found differences in patterns with respect to date and territory density, suggesting a role of spatiotemporal variation in parental defense in producing date- and territory-related patterns.
