Red Birds in Louisiana

Around mid-April at Grand Isle - a barrier island seven miles long on Louisiana’s southern coast - the live oaks sometimes fill overnight. Scarlet Tanagers. Gray Catbirds. Mixed warblers. Birds that crossed the Gulf of Mexico in darkness land in the first trees they find, and for a few hours the canopy holds colour that has no business being there. The Audubon Society’s field guide to Louisiana birding records a species list at Grand Isle that tops 300. Most are passing through. The red birds of Louisiana are a different matter.

Four of them have a genuine claim on the state: one year-round, one that breeds here, one that passes through in spring, and one that arrives in winter.

The permanent resident: Northern Cardinal

Cardinalis cardinalis is the only red crested bird in North America, and in Louisiana it is everywhere: suburbs, woodland edges, bayou thickets, the brushy margins of sugarcane fields. Males are brilliant red from bill to tail-tip. Females are warm buff-brown with red tints on the crest, wings, and tail, both sexes carrying the same thick coral-pink bill built for cracking hard seeds.

The Audubon field guide lists the Northern Cardinal as abundant in the Southeast, a permanent resident that breeds two to three broods per year and has expanded its range steadily over the past century. The bird does not migrate and does not fade in winter. That constancy makes it easy to overlook. The Northern Cardinal field guide covers the full biology, including the post-moult colour change that makes males appear duller in October than they will in March.

The breeding species: Summer Tanager

Piranga rubra arrives in Louisiana in spring and stays to breed, making it the only fully red migratory songbird that nests in the state. The Audubon field guide describes adult males as “bright rosy red all year” - no black, no streaking, just an even red from crown to undertail. Females are yellow.

Summer Tanagers breed in dry open oak, hickory, and pine woodlands. Kisatchie National Forest, in central Louisiana, holds this habitat. The song resembles an American Robin’s but softer and sweeter; the call is a rattling chick-tucky-tuck. Eastern and central populations cross the Gulf to wintering grounds in Central and South America, so Louisiana sits in the arrival corridor each April.

The spring migrant: Scarlet Tanager

Piranga olivacea passes through Louisiana in spring and is one of the species recorded during Grand Isle fallout events. The Audubon field guide describes breeding males as “our only brilliant red bird with black wings and tail.” They are not breeders in Louisiana. They cross the Gulf northbound at night, land on the coast when conditions force it, then continue north to oak forests in the northeastern United States.

The Scarlet Tanager crosses the Gulf of Mexico at night in spring. It does not breed in Louisiana. The bird perched in the live oaks at Grand Isle in mid-April is resting before it leaves.

By late summer males moult into greenish plumage with black wings. If you see a Scarlet Tanager in Louisiana, it is almost certainly April or early May.

The confusion point is the Summer Tanager. The distinction is simple: the Summer Tanager is red all over with no black, while the Scarlet Tanager in breeding plumage has jet-black wings visible at any distance.

The winter finch: Purple Finch

Haemorhous purpureus arrives in Louisiana in winter from northern breeding grounds. The Audubon field guide describes the male as showing “an old-rose color” - more raspberry than purple, and more uniform than its close relative. Purple Finches are chunkier and shorter-tailed than House Finches, and females show a much stronger face pattern.

The House Finch - Haemorhous mexicanus - is a year-round presence in Louisiana suburbs. Males show red on the forehead, chest, and rump, but the red is restricted and the flanks carry brown streaking. The Purple Finch is an irregular winter visitor rather than a guaranteed resident, arriving in numbers during years when food is scarce in the north.

The painted standout: Painted Bunting

Passerina ciris sits in a category of its own. Males carry a blue head, red underparts and rump, and a green back - a combination improbable enough that Louisianans called the bird the nonpareil, French for “without equal,” as the American Bird Conservancy records. Females are bright yellow-green with a pale eye-ring.

The western breeding population, which includes Louisiana, nests in dense brush, hedgerows, and woodland edges from late April through early August. The Audubon field guide notes population declines in recent decades linked to habitat loss, and the cage-bird trade continues to pressure the species on its wintering grounds.

The Painted Bunting is not fully red in the way the Summer Tanager is - the red sits on the underparts and rump of an otherwise multi-coloured bird. But when a male feeds in low coastal scrub on a clear May morning, the red is what catches the eye first.

---

Louisiana does not merely host red birds in passing. It breeds them, winters them, and catches them mid-crossing. Few states in the eastern United States can claim the same four-season spread: the cardinal year-round, the Summer Tanager in the pines from April, the Scarlet Tanager overhead at Grand Isle in mid-April and then gone, the Purple Finch at winter feeders when the north pushes it south. The Painted Bunting in the coastal scrub, small and improbable, stays to breed. That is five reasons to keep a pair of binoculars near the window regardless of the month.
