Figure 1 in Spina et al. (2025): "Study site and species: Savannah sparrows of Kent Island, New Brunswick. a) Map of the Three Islands (Kent, Hay, and Sheep Island). The map shows the location of the Three Islands in the Bay of Fundy, and the long-term Savannah sparrow study area (North Field and South Field, in orange). The lighter green areas of the Three Islands represent grassland breeding habitat for Savannah sparrows and the darker green area represents the area on Kent Island covered by spruce forests.
