Red Birds in South Dakota
Stand in the ponderosa pines of Custer State Park in January and listen for the sound of scissors. That dry, crossed-bill snipping noise is a Red Crossbill feeding in the canopy - a bird that has spent its entire life in these Black Hills forests and has never needed to go anywhere else.
That is the argument this piece wants to make: South Dakota is not one state for red-plumaged birds, it is two. The grassland-and-riparian east belongs to the cardinal and the finch. The ponderosa pine hills in the west belong to species that depend on that specific forest and would disappear if it did. The Missouri River is not a boundary on a map. It is a genuine ecological line.
The eastern species
The east is familiar to anyone who has watched a backyard feeder in Illinois or Ohio. Cardinalis cardinalis, the Northern Cardinal, reaches the western edge of its range in the river-bottom woodlands along the Big Sioux and James rivers. He does not cross into the short-grass prairie. He needs dense shrubby cover for nesting and the eastern riparian corridors give him exactly that. South Dakota is as far west as most birders will ever find a cardinal - and the birds here are genuine year-round residents, not just passing through.
The House Finch is common in every South Dakota town. He is red at the head and breast only, streaky elsewhere, and his song is a long loose warble that runs through spring mornings from Sioux Falls to Rapid City. He is not native to the east - he was released from captivity in New York in 1940 and spread across the continent - but he is fully established and shows no sign of retreating.
South Dakota divides neatly into two bird worlds at the Missouri River, and the species that mark each side are not interchangeable.
The Rose-breasted Grosbeak, Pheucticus ludovicianus, passes through in May heading north, the male carrying a vivid red triangle on a white breast. He is a migrant in this state, not a breeder. He does not stay. The Red-headed Woodpecker, Melanerpes erythrocephalus, does breed in the east - open woodland with dead standing timber is his preference and the oak savannas around Big Sioux Recreation Area hold small colonies.
| Species | Red feature | Typical range in SD |
|---|---|---|
| Northern Cardinal | Full red (male) | East of Missouri River |
| House Finch | Red head and breast (male) | Statewide in towns |
| Red-headed Woodpecker | Entirely red head | Eastern woodlands |
| Rose-breasted Grosbeak | Red breast triangle (male) | Migration only |
| Common Redpoll | Red forehead cap | Winter feeders statewide |
The Black Hills species
The Black Hills are an anomaly. They rise some 4,000 feet above the surrounding plains in the southwestern corner of the state, a forested island in a grassland sea. The ponderosa pine forests here are the nearest thing on the northern plains to the Rocky Mountain west, and they hold species that have no other South Dakota address.
Loxia curvirostra, the Red Crossbill, is the signature bird. He extracts seeds from pine cones with a bill whose tips cross each other like misaligned scissors - a specialisation so complete that he nests in winter if the cone crop is good, because the cones are there and the calendar is irrelevant. Red Crossbills in the Black Hills are not strictly resident: they track cone production across the landscape and will leave a forest when the crop fails. Long-term monitoring by South Dakota birders has found them present most winters in Custer State Park and the Norbeck Wildlife Preserve, but absent from both in years of poor cone set.
The Pine Grosbeak, Pinicola enucleator, appears in the Black Hills in some winters but not others. The male is rose-pink rather than red, large for a finch, slow-moving in the canopy. He is not reliably found every year and a first sighting here feels earned.
For birds with orange tones rather than pure red, the patterns shift as you cross the continent - compare what turns up in Arkansas or Illinois in autumn and the species lists begin to overlap only where the ranges of finches and thrushes intersect.
Where to look
Custer State Park covers the southern Black Hills and holds Red Crossbills in the ponderosa stands along Wildlife Loop Road. The open meadows also attract Northern Flickers in the red-shafted western form - the shafts of the flight feathers glow salmon-pink in the hand, and in flight the underwings flash the same colour.
Bear Butte State Park, northeast of Sturgis, is a migration stopover for grassland and woodland birds. In late April and early May the slopes hold Rose-breasted Grosbeaks heading north and the occasional Purple Finch in raspberry-wash plumage.
LaCreek National Wildlife Refuge in the south sits in the transition zone between prairie and the Missouri River drainage. The riparian edge is the best eastern-SD habitat for cardinals if you have only one afternoon to spend.
The argument in brief
The species worth travelling to South Dakota to see are not the cardinals - those you can find closer to home if you live anywhere east of the Mississippi. The birds worth the drive are the crossbills in the Black Hills, because there is no other isolated pine forest like it on the northern plains, and the crossbills know it. The cone crop sets the terms. Come in winter when it is good and the forest rings with that scissoring sound for half a mile in every direction.
The cardinal, for all his brightness, is a widespread species doing well across the eastern half of the continent. The Red Crossbill in the Black Hills pines is something closer to a local specialist - tied to a specific forest, in a state that most birders cross at speed on I-90 without stopping.
Stop.
