Interspecific attraction between ground-nesting songbirds and ants: the role of nest-site selection

Table 4 The results of model-averaging across the top candidate models with Δ AICc < 2 (Table 3) investigating the likelihood of an ant brood occurring in a Wood Warbler nest in relation to the stage of bird nest, ambient temperature and rainfall preceding nest failure or fledging of chicks, the delay of bird nest collection from the field, and year
