The Connecticut Warbler is an infamously hard-to-find bird that forages on the ground in remote muskeg, spruce bogs, and poplar forests. The Connecticut Warbler is seasonally monogamous and territorial, the males establishing and defending territories ranging in size from about 1/4 hectare (0.6 acres) in open forest to 1/2 hectare (1.25 acres) in closed forest, where terrestrial arthropod densities are lower. This range map was created by attributing sub-watershed polygons with information of a species' presence, origin, seasonal and reproductive use.

Strimas-Mackey, O. Robinson, S. Ligocki, B. Petersen, C. Wood, I. Davies, B. Sullivan, M. Iliff, S. Kelling. This range map was created by attributing sub-watershed polygons with information of a species' presence, origin, seasonal and reproductive use. The known range for a species can be used to constrain the boundaries of the species distribution model and in assessments of the conservation status and/or threats within the range of a species.
