- axr, axb, percentage of axial recordings, and axial mean vectors of birds, respectively (both as defined in text); med rb, median vector length of the individual birds, representing the intra-individual variance; αN, rN, grand mean vector or axis (non-significant axes in parentheses), with asterisks at rN indicating significance by the Rayleigh test: n.s., not significant; * P < 0.05; ** P < 0.01 and *** P < 0.001.
