Table 2 (A) Top model set (ΔAICc ≤ 2 from best model), and (B) model-averaged estimates of predictors included in the top models for Ta-max (46 °C or less) and trial completion (i.e. stayed 15 min at Ta-chamb = 46 °C).

From: Thermal acclimatisation to heatwave conditions is rapid but sex-specific in wild zebra finches
