Hi, Consulting the Ohio Breeding Bird Atlas 2 data will yield some good information on rare Ohio breeding species. Lake and Geauga counties host or have hosted several of these. With Merlin, Common Loon, and Black-throated Blue Warbler being 3 confirmed species. The latter 2 were first breeding records for Ohio, (although a 2nd Merlin nest was found in the project) Black-throated Blue Warbler was the first nesting of that species in Ohio in 80 years. The Glaciated Allegheny Plateau of the extreme NE part of the state has unique habitats and so the breeding bird populations are somewhat different from other areas. Dark-eyed Juncos are increasingly common nesters. Canada Warblers are occasional breeders. Blackburnian Warbler is a very very rare nester.
