Discriminant analysis ordination for oenanthe males from different study sites using morphometric measurements only or morphometric and isotopic measurements combined. Morphometrics only: LD1 = −0.54*Tarsus-0.08*Wing chord-0.84*Bill length-0.50*Bill width + 0.37*Bill depth-4.50*c2-0.53*c3; LD2 = −0.13*Tarsus + 0.22*Wing chord-0.41*Bill length-2.40*Bill width-1.86*Bill depth + 5.13*c2-0.27*c3. Morphmetrics and isotopes: LD1 = −0.26*Tarsus-0.27*Wing chord-1.03*Bill length-0.35*Bill width-0.91*Bill depth-1.09*c2-1.21*c3-0.09*δ2H + 0.26*δ15N + 0.02*δ13C; LD2 = 0.36*Tarsus + 0.13*Wing chord + 0.66*Bill length-0.80*Bill width-0.67*Bill depth + 5.97*c2 + 0.06*c3-0.04*δ2H + 0.25*δ15N + 0.15*δ13C.
