First column: positions of the release sites with respect to the anomaly:C, control site outside anomaly; B, sites at the border of the anomaly; A,sites within the anomaly; names of the release sites, home direction and distance to home, altitude above NN. Fam?, the familiarity of the birds with the site: ufs, unfamiliar with the site; fs, familiar with the site. N (N_b), number of pigeons released and, in parentheses, number of evaluable bearings; α, mean vanishing bearing;Δh, their difference to the home direction, with + indicating a difference to the right and – a difference to the left and non-significant mean bearings given in parentheses; r, length of mean vector,with asterisks indicating significance by the Rayleigh test(Batschelet, 1981). Van. int.,median vanishing interval in minutes:seconds; Home, percentage of pigeons that returned; Speed, median homing speed in km h^–1. Significance levels: ^*P<0.05; ^**P<0.01; ^***P<0.001; n.s. not significant
