Estimated migration routes for male Canada Warblers tracked from three breeding populations across the breeding range from 2014 to 2016. Blue tracks represent the fall migration routes taken by 4 individuals that were tracked from Alberta (a), red tracks represent the fall migration routes of 8 individuals from Manitoba (b), green tracks represent the fall migration routes of 6 individuals from New Hampshire (c), and the yellow track shows the spring migration track taken by one individual returning to New Hampshire (d). Dashed lines show inferred routes when latitude estimates were poor. The error bars indicate the average 95% credible intervals for the overwintering locations shown for each breeding population. The figure was generated in R [54] and the Canada Warbler range map was provided by Environment Canada [18]
