Red Birds in Alabama

On a late-April morning at Dauphin Island, the trees along Bienville Boulevard can hold three red birds at once - a male Summer Tanager in the oaks, a Scarlet Tanager resting after the Gulf crossing, and a Northern Cardinal working the hedge below. All three are red. None of them is red in the same way.

That distinction is what Alabama’s red birds are actually about, and most field guides skip it entirely.

The four species worth knowing

Species	Red feature	Season	Habitat
Northern Cardinal	Male entirely scarlet	Year-round	Gardens, edges, thickets
Summer Tanager	Male entirely rosy-red	Late April - September	Pine-oak woodland
Scarlet Tanager	Male red with black wings	Spring migration	Mature deciduous forest
Painted Bunting	Red breast and rump (male)	Spring migration, some breeding	Dense brush, scrubby edges
House Finch	Red head and breast (male)	Year-round	Suburbs, feeders
Purple Finch	Raspberry-red wash (male)	Winter	Woodlands, feeders

The year-round resident: Northern Cardinal

Cardinalis cardinalis is present in every county and every season. Outdoor Alabama describes its habitat as “woodland edges and clearings, brushy areas, thickets, riparian woodlands, parks, suburban gardens, and residential areas.” Breeding runs from March through September. The Audubon field guide gives measurements at 8 to 9 inches long and 1.5 to 1.7 ounces - robin-sized, which is why a male at a feeder reads as large.

The scarlet comes from dietary carotenoids. Cardinals cannot synthesize red pigment internally. They absorb yellow and orange carotenoids from seeds, berries, and insects and convert them to red ketocarotenoids using an enzyme called CYP2J19. A 2026 paper published in Ornithology found that captive male cardinals had “significantly lower relative concentrations of red carotenoids in both follicles and plasma” than wild birds, even with identical diets - suggesting that physiological stress suppresses the conversion pathway. The cardinal’s brightness is not just a matter of diet. It is a measure of how the bird is coping.

A male cardinal’s redness is not a colour. It is a condition report.

The summer breeder: Summer Tanager

Piranga rubra is the only entirely red songbird that breeds north of the Gulf of Mexico, and Alabama holds it reliably. He arrives in late April and stays through September, favouring “dry open woods, especially those of oak, hickory, or pine,” according to the Audubon field guide. His red is a warmer, more orange-rosy shade than the cardinal’s pure scarlet, and he is slightly smaller at 6.7 to 7.5 inches and 0.8 to 1.1 ounces.

He does not come to feeders. He hunts bees and wasps. The Audubon guide notes he “has no fear of stinging insects, often raiding wasp nests” and will break into them to eat the larvae. Watch the canopy of mixed pine-oak woodland in May and listen for a burry, robin-like song - cleaner and less metallic than the cardinal’s.

The migrant: Scarlet Tanager

Piranga olivacea in breeding plumage is what the Audubon field guide calls “our only brilliant red bird with black wings and tail.” He crosses the Gulf of Mexico at night in spring and stops on the Alabama coast when he runs out of fuel or meets a weather system. Dauphin Island, which Audubon describes as a “fallout” site with “more than 320 species” recorded, is where most Alabama sightings happen. Fort Morgan, at the tip of the peninsula, is the second site. The window runs mid-April to mid-May.

The Scarlet Tanager’s red is also carotenoid-based, but unlike the cardinal he discards it entirely between breeding seasons. By late summer he has moulted into green plumage with dark wings - a different-looking bird that will be red again next spring. The Audubon field guide confirms his winter grounds: “tropical rain forest in lowlands just east of the Andes.” He winters in South America and passes through Alabama twice a year.

The edge case: Painted Bunting

Passerina ciris carries blue, green, and red in separate sections - blue head, green back, red breast and rump. The French gave him the name “nonpareil,” which Audubon translates as “having no equal.” His red is restricted to his underparts, so he reads differently in the field from a tanager.

In Alabama he appears mainly during spring migration along the Gulf Coast, most reliably at the same coastal sites as the Scarlet Tanager. He is classified as near threatened. The Audubon guide cites habitat loss and illegal capture for the cage-bird trade as the primary pressures on the species. Eastern populations winter in Florida and the Caribbean. A Painted Bunting in a coastal Alabama thicket in late April is worth stopping for.

The finches

Two smaller birds add red at a different scale. The House Finch (Haemorhous mexicanus) is a year-round resident, found in suburbs and urban areas across the state. The red in males is carotenoid-based and varies with diet - Audubon notes that some males show orange or even yellow rather than red, which is a direct read of what the bird has been eating. He is five to six inches, compact, and most reliably found at feeders.

The Purple Finch (Haemorhous purpureus) is a winter visitor. The Audubon guide describes his colour honestly as “dull red” rather than the vivid tone the name implies. He is chunkier and shorter-tailed than the House Finch, and the female’s bold facial striping makes her easier to identify than a female House Finch. Purple Finches arrive in autumn and depart by early spring.

Where to go

For the Northern Cardinal, any Alabama garden with dense shrub cover will do. It is consistently the most reported bird on Alabama eBird lists.

For the Summer Tanager, drive into open pine-oak woodland in central Alabama in May. Listen for the song before scanning the canopy.

For the Scarlet Tanager and Painted Bunting, Dauphin Island is the primary target during mid-April to mid-May. A cold front after a south wind overnight is the best setup. Fort Morgan on the peninsula tip is productive for the same reasons.

Wheeler National Wildlife Refuge in the Tennessee River valley runs “more than 260 species” across its wetland and forest habitats, according to Audubon’s Alabama guide. Cardinals and woodpeckers are year-round there. Winter brings Purple Finches to feeder areas.

Timing across the year

Spring migration peaks here weeks before it reaches the Midwest. Summer Tanagers arrive in late April, well ahead of their appearance in Ohio or Michigan. Painted Buntings are most visible in May before the coastal scrub fully leafs out. Cardinals and House Finches hold their positions every month.

The pattern across all of Alabama’s red birds is the same: the colour is metabolically expensive, diet-dependent, and honest. What varies is whether a given bird can afford to maintain it all year or only in the season when it matters most. Alabama, by geography and climate, lets you see the full range of that calculation in a single May morning.
