Table 1 Results of averaged models (all models with AICc value ≤2) on the propensity to call, and the number of call per interaction bout, with estimated means (EM), adjusted standard errors (SE), z values, and lower and upper confidence intervals (CI)

From: Calls during agonistic interactions vary with arousal and raise audience attention in ravens
