Table 1.

Predictors of egg rejection in experimentally parasitized nests. I (%) is the proportion of overall variance explained by the model (36.7%) contributed by each variable independently. VIF indicates variance inflation factors for each predictor. d.f. = 116. Significance levels: ** p < 0.01, * p < 0.05.
