Table 3 The results of model selection using the corrected Akaike Information Criterion (AICc) testing the likelihood of an ant brood occurring (present or absent) in a Wood Warbler nest (response variable) in relation to covariates of the stage of a bird nest, ambient temperature and rainfall preceding fledging of chicks or nest failure, the delay of bird nest collection from the field, and year
