F _IS, F _ST, relatedness (R), mean assignment index (mAI _C) and variance of mean assignment index (vAI _C) were estimated on males and females considering either single populations or by separating Spanish barn swallows from all other ones. Significance (P) (two-tailed test) was assessed using the randomization method of [10]; *, P<0.05.
