The primary objective of this study is to assess if urine from domestic dogs increases perception of risk and inhibits foraging activities of wildlife, including ground foraging birds, small mammals, and mesocarnivores, in coastal California. We will test the effects of dog urine presence on wildlife foraging by placing a sample of either domestic dog urine or water near artificial foraging patches where foraging activities are quantified as Giving-Up Densities (GUD). We will establish a wildlife camera near each foraging patch to identify all species foraging in the patch. We hypothesize that if animals perceive domestic dog urine as a direct cue for risk, GUD should be greater at foraging patches with urine present than at control patches where urine is not present. We predict higher GUD in foraging patches near domestic dog urine than patches near water for small mammals and mesocarnivores, but because ground foraging birds rely less on olfaction that mammalian species, we predict no differences in GUD for birds. Information on how domestic dog urine affects the perception of risk for wildlife will increase our understanding of the effects of domestic dogs on wildlife behavior and will be useful for managing their presence in natural areas.
