Fig. 4From: Widely distributed breeding populations of Canada warbler (Cardellina canadensis) converge on migration through Central AmericaAverage 95% credible intervals for a) latitude and b) longitude values derived by FLightR analysis for 18 male Canada Warblers tracked with light-level geolocators from breeding sites in Alberta, Manitoba and New Hampshire. The dotted lines around the longitude curves indicate plus or minus one standard deviation. The fall equinox is indicated by the red vertical lineBack to article page
