Fig. 3

Average overwintering locations for 25 male Canada Warblers from three different breeding sites determined by using light-level geolocators. The breeding and wintering range are indicated with grey shading. The black triangles indicate individuals that bred in Alberta (n = 10), white circles indicate individuals that bred in Manitoba (n = 9), and the grey squares represent individuals that bred in New Hampshire (n = 6). The error bars indicate the mean 95% credible intervals for all the overwintering locations. The figure was generated in R [54] and the Canada Warbler range map was provided by Environment Canada [18]
