Ohio Division of Wildlife Brewer’s Blackbird. It is almost surprising that this uch has changed regarding the status of Ohio’s species has not been documented nesting in Ohio yet. M nesting birds since the earliest ornithologists Brewer’s Blackbird would be easy to overlook, as began documenting the state’s bird life. Two former possible nestings would be in a region that isn’t heavily breeders are extinct, and seven species are extirpated birded, and it would certainly be possible to dismiss (gone from Ohio; still nest elsewhere). Unfortunately, it them as other more common blackbirds like Common seems likely that two others will join that latter category Grackle without a careful look. They would also likely eventually; the Golden-winged Warbler and Loggerhead occur in towns, parks, farms or other well-settled and Shrike. Other species have been added as confirmed relatively uninteresting areas that could easily be nesters in the past five years, though, like Canvasback ignored by birders. and Common Merganser. Brewer’s Blackbirds began an eastward expansion Nearly twenty long, significant years around the 1920’s, and have have passed since bird atlasers colonized as far east as southern turned in their last data sheets from Michigan and eastern Ontario, the Ohio Breeding Bird Atlas I.

There is competition that the new survey will result in new between the two species, and in additions to our breeding avifauna, some areas grackles dominate and and this article presents some apparently exclude Brewer’s thoughts on species to be on the Blackbirds in suburban sites.

Populations of this small falcon are steadily one because as far as we know, stilts have yet to growing, and migrants and wintering birds are successfully breed in Ohio. This could represent the becoming more frequent in Ohio. Breeding populations first of future nesting attempts by this species, which are increasing, and Merlins appear to be recolonizing may have bred in Ohio’s wet prairies historically. former nesting regions, and perhaps spreading into new Recent major wetland restoration projects within the areas.

If nesters were to appear in Ohio, the St. Marys River in western Ohio, primarily in Mercer County, and the Ohio River Valley in the vi- cinity of Brown, Clermont, and Hamilton counties might be likely locales. The lower valley of the Great Miami River is another potential area. Ring-necked Duck. This duck nests widely across southern Canada and the northern U.S., within 150 or so miles of northern Ohio. They will sporadically nest well south of their primary breeding range, and have bred on the Pennsylvania side of Pymatuning Lake, which shares a border with Ohio in Ashtabula County. Should be watched for in larger wetlands in Ashtabula, Geauga, Portage, and Trumbull counties, and Singer Lake in Summit County. Yellow-rumped Warbler (Dendroica coronata)© Swainson’s Warbler.
