Wisconsin Important Bird Areas

Conserving the most important places for birds

Adams County Pines

Site Description

This IBA, located on private industrial forest land in Adams County, is home to the breeding sites for a pioneering population of the federally endangered Kirtland’s warbler, which has been documented as breeding here since 2007, with at least 61 young fledged as of 2012.  The site is characterized by extensive, mostly young red pine plantations with inclusions of jack pine, black oak, and northern pin oak, and scattered openings vegetated with Penn sedge, grasses, blueberry, and forbs.

Ornithological Importance

Aside from containing the first documented nesting population of Kirtland’s warbler in recorded Wisconsin history, this site also provides habitat for other young conifer forest and “barrens” birds, including ruffed grouse, brown thrasher, Nashville warbler, field sparrow, clay-colored sparrow, and vesper sparrow.
