Variables with a cumulative variable AICc weight greater than 0.5 (italics) are considered important. Cells with a dash indicate that models would not converge with the inclusion of that variable. ψ variables are those considered when evaluating prevalence. p variables are those considered when evaluating detection probability. “PCR run” indicates the three PCR replicates carried out for each sample. “Nest” indicates nest type (open, ground, or cavity). BCI is body condition index defined as the ratio of body mass (g) to tarsus length (mm) for each individual
