  1. All models with a ΔQIC < 5 are shown. QIC = quasi-likelihood information criterion[34], ΔQIC = difference between focal model and model with lowest QIC value, weight = relative probability of focal model within candidate set. Warning call = warning call heard or not; group size; age: age of non-breeder; habitat = proportion unmanaged forest on territory; kinship: kinship of non-breeder in relation to breeder.
