(a) Winter distribution (blue contours) of Savannah sparrows from a breeding population on Kent Island, NB, Canada (orange arrow) inferred from geolocator tracking data collected from 2011 to 2014. Blue contours delineate the 30, 50 and 75% kernel densities estimated from the winter locations of 38 individuals. Embedded photo shows a colour-banded Savannah sparrow (photo courtesy of S. Doucet). (b) Long-term study area (orange) on Kent Island, with Sheep Island to the west and Hay Island to the north (north arrow in a also applies to b).
