Description of Bird Conservation Region 12
This region is characterized by coniferous and northern hardwood forests, nutrient poor soils, and numerous clear lakes, bogs, and river flowage. All of the world's Kirtland's Warblers breed here, as do the majority of Golden-winged Warblers and Connecticut Warblers. Great Lakes coastal estuaries, river flowage, large shallow lakes, and natural wild rice lakes are used by many breeding and migrating water birds. Yellow Rail are among the important wetland species, and islands in the Great Lakes support large colonies of Caspian and Common Terns. Although breeding ducks are sparsely distributed, stable water conditions allow for consistent reproductive success. Wood Duck, Mallard, American Black Duck, Ring-necked Duck, and Common Goldeneye are common breeding species in this region. Threats to wetland habitat in the Boreal Hardwood Transition Region include recreational development, cranberry operations, peat harvesting, and drainage.
