The loadings on (A) axes one and two and (B) axes one and three for monthly mean dew point temperature (tdmean), monthly precipitation (precip), and monthly maximum temperature (tmax) are shown. Points are coloured by sampling location and the grey cloud in the center of each plot shows the 128,147 SNPs included in the analysis. The four subspecies of willow flycatcher are shown as different shapes.
