Red Birds in Ohio: Cardinal, Tanager, and the Others

A male Scarlet Tanager arrives in an Ohio oak forest in mid-May, fresh off a Gulf crossing, and he looks wrong: all that electric red set against black wings, moving quietly through a canopy that has barely leafed out. He has no business being that colour in a temperate woodland. He cannot help it.

Ohio has seven red-plumaged birds worth knowing by name. Most residents see exactly two: the cardinal at the feeder and a flash at the thicket edge. The others require habitat, and knowing what each species needs is the whole difference between seeing the list and missing it.

The permanent resident: Northern Cardinal

Cardinalis cardinalis is Ohio’s state bird, adopted in 1933, and the only red bird guaranteed in every county in every season. The species was not always so abundant here. By the late 19th century it had pushed north into Ohio, reaching Lake Erie by around 1900. Ohio History Central attributes the expansion to three factors: warming winters, suburban growth creating edge habitat, and the spread of winter feeding stations.

Cornell Lab’s All About Birds puts the total population at 130 million. The male’s red plumage comes from carotenoid pigments absorbed from native fruit - dogwood berries, wild grapes, mulberries - not manufactured internally. Females select mates partly on plumage brightness, which means the August molt and its bald-headed collapse is quietly preparation for March. That process is covered in What the bald cardinal in August is for.

Cardinals breed two to three times per year in Ohio, occasionally four. The species does not migrate and does not molt into a dull winter plumage.

The forest fire of May: Scarlet Tanager

Piranga olivacea spends its breeding season in the canopy of mature deciduous forest, often 30 or more feet up in oaks, maples, and beeches. The male is brilliant red with black wings and tail. The female is dull yellow-green. Both are overlooked by most Ohio visitors because the species rarely comes low.

Audubon’s Field Guide puts the Scarlet Tanager’s population at approximately 2.6 million and notes it “does poorly in smaller forest fragments.” The North American Breeding Bird Survey recorded a roughly 14 percent decline between 1966 and 2014, driven by forest fragmentation and cowbird parasitism. Southeast Ohio - the unglaciated Appalachian plateau with its connected hardwood blocks - is the reliable breeding stronghold.

The Scarlet Tanager is the species most Ohio birders want to see and the one most often missed. Find a mature stand at least 20 acres across, stop at the edge in early morning, and listen for the burry, raspy song before looking up.

Spring migrants arrive from mid-May onward. By late July males begin molting out of breeding plumage into greenish with black wings retained. By September most have left, wintering in lowland forest east of the Andes. The orange birds in Ohio guide covers Baltimore Orioles, which arrive on the same May schedule.

Partial-red residents and visitors

House Finch (Haemorhous mexicanus) is year-round across the state. Only the male carries red - a wash on the head and breast, sometimes replaced by orange or yellow depending on diet during molt. Audubon documents the entire eastern population descending from birds released in New York in 1940 by a pet dealer who had been selling them illegally as “Hollywood Finches.” Within 50 years their descendants had spread to the Great Plains and met the native western population there.

Purple Finch (Haemorhous purpureus) visits Ohio in winter, arriving in October. Audubon describes the male’s color as “dull red on head and foreparts” - more a wine wash than the clean red of the cardinal. Tell the two finches apart by the female: the Purple Finch has a strong dark whisker and clear white eyebrow that House Finches lack.

Red-headed Woodpecker (Melanerpes erythrocephalus) is a year-round Ohio resident in decline. The Audubon Ohio Watch List documented a 78 percent population drop in the state, with numbers falling to an estimated 35,000 birds. Loss of dead standing trees, competition with European Starlings for nest cavities, and road strikes are the documented causes. Western Ohio’s open woodlots hold more birds than the denser east.

The irregular and the irruptive

Summer Tanager (Piranga rubra) - adult male all-red with no black on the wings - breeds in dry pine-oak woodland across the American South and reaches Ohio only near its northern range edge, in river counties of the south. Records are scattered. Where it occurs, Audubon notes it specializes in bees and wasps taken in flight.

Crossbills and Common Redpolls appear in Ohio only when boreal seed crops fail to the north. Some winters bring good numbers. Others bring none.

Where the list leaves you

The Northern Cardinal species page covers identification and behavior in full. The orange birds in Illinois and orange birds in Michigan lists share several of the same forest migrants on the same May-to-September window, and are worth checking if you are building a broader Midwest picture.

The Scarlet Tanager’s dependence on large, connected forest blocks makes him a proxy for forest health: where he breeds consistently, the woodland is intact. Where he has disappeared from previously reliable sites, the stand has been fragmented past the threshold his territory requires. Watching for him is, quietly, a way of watching the forest itself.
