Red Birds in New Hampshire

Stand at a White Mountain spruce-fir treeline in October and you will hear Red Crossbills before you see them. A staccato series of kip-kip-kip notes cuts through the canopy and then a loose flock lands in the spruces - brick-red males, yellow-olive females, every bird indifferent to your presence. They are here because spruce cones are here. Next October they might be in Quebec. The crossbill does not have a territory. It has a continent.

That restlessness is the key to New Hampshire’s red-bird list. The state sits at the edge of two completely different bird worlds - the boreal forest of the north and the temperate deciduous zone of the south - and red-plumaged species occupy both. Some are year-round residents who ignore the cold. Some are summer breeders who appear for one season and vanish. Some, like crossbills and Pine Grosbeaks, are irruptive wanderers who arrive only when the cone crop fails further north. The most famous red bird, the Northern Cardinal, has spent the last 50 years pushing steadily northward up the Connecticut River valley. It is now a common feeder bird in Concord and Manchester. It was not always.

The one worth singling out: the Scarlet Tanager

Of all New Hampshire’s red birds, Piranga olivacea is the one that earns a separate paragraph. The male in June is, without qualification, the most dramatic bird in the state’s deciduous forests - a bird so red, against wings so black, that first-time observers frequently refuse to believe it is native. He is. He nests here, typically in oak-dominated canopy where he forages quietly 20 metres up and is heard far more often than he is seen. The song is a hoarse, robin-like phrase repeated in series. The call is a sharp chip-burr that field guides describe as distinctive once you know it and useless as a description until you do. By September the male has moulted into greenish-yellow, and he leaves for South America looking nothing like the bird that arrived.

The Scarlet Tanager’s New Hampshire range is concentrated in the southern and central counties where mature oak stands persist. Long-term monitoring by ornithologists has shown that this species is sensitive to forest fragmentation - pairs nest in interior forest, not edge habitat, and a woodlot below a certain size simply will not hold them. If you want to find one, Pisgah State Park and the mature stands around Lake Sunapee are reliable. A forest road at dawn in late May is more productive than any field guide.

New Hampshire’s red birds split cleanly into two communities: the boreal specialists above 2,500 feet, driven by cone crops and indifferent to state lines, and the temperate species below, tied to deciduous forest and now to suburban feeders. The White Mountains are the dividing line.

Purple Finch vs House Finch: a distinction worth making

New Hampshire birders encounter this identification question constantly, especially at winter feeders. The two species look similar enough that they fooled ornithologists for years. The short version: the Purple Finch male is more deeply saturated, with a raspberry wash that covers the head and flows down the breast without clear boundaries. The House Finch male is brighter red but concentrated at the forehead, eyebrow, and rump, with distinct brown streaking on the flanks. The House Finch is the one more likely to visit suburban feeders in southern New Hampshire year-round. The Purple Finch breeds in the state’s mixed forests and may move to feeders in winter, but it is not as reliably sedentary.

The Cornell Lab’s Project FeederWatch data shows House Finches consistently outnumbering Purple Finches at New Hampshire feeders across recent winters. That ratio reflects a national pattern: the House Finch, introduced in the east from western birds released on Long Island in the 1940s, has become one of the most abundant feeder birds in the region. The Purple Finch has declined modestly over the same period. Both species take black-oil sunflower readily. If you want to tell them apart at a feeder, wait for the bird to turn. Purple Finch males show a more uniformly suffused head. House Finch males wear their colour like a dipped paintbrush.

The crossbill question is different. If you hear kip-kip and see red birds working spruce cones in the White Mountains, you are almost certainly looking at Red Crossbills. White-winged Crossbills share the habitat but are distinguished by two white wing bars and a slightly paler, pinker red. Both species have the crossed mandibles for which the genus is named - a bill so specialized for prying cone scales that the birds have essentially made themselves dependent on cone production and freed themselves from geography in exchange. For more on how red plumage and habitat link up across neighboring states, the patterns described for orange birds in Michigan and orange birds in Ohio offer useful comparison, since many of the same migratory species move through those states on the same breeding flyways.

Seasonal expectations

Spring (late April to May): The most concentrated arrival. Scarlet Tanagers and Rose-breasted Grosbeaks return to deciduous forests in the last two weeks of May. Ruby-throated Hummingbirds reach southern New Hampshire by early May. This is the best month for hearing Scarlet Tanagers sing from the canopy.

Summer (June to August): Breeding season for the forest nesters. Tanagers become quiet and harder to locate as incubation begins. Cardinals are active at feeders throughout southern NH. Crossbills may be present or entirely absent depending on the cone crop.

Autumn (September to October): Tanagers and grosbeaks move south, and the male tanager’s green-yellow alternate plumage makes him unrecognizable at first glance. Irruptive finches can arrive any time from late September depending on boreal conditions. This is when crossbill irruptions peak.

Winter (November to March): Cardinals at feeders, House Finches and Purple Finches at nyjer and sunflower. Pine Grosbeaks arrive in irruption years - large, dove-sized finches working mountain-ash berries at forest edges. Crossbills may be present at any elevation with cone-bearing conifers.

Where to go

The White Mountain National Forest is the obvious destination for boreal specialists. Route 302 through Crawford Notch and the Kancamagus Highway both pass through habitats where crossbills and grosbeaks are possible from October through March. For Scarlet Tanagers, the mature oak-hickory stands of southern New Hampshire - Pisgah State Park in Cheshire County, Pawtuckaway State Park in Rockingham County - are more productive than the mountains.

For Cardinals, Manchester and Nashua have established breeding populations. A sunflower feeder anywhere south of Concord will likely draw at least one pair by winter. The Northern Cardinal’s northward range expansion over the past several decades is one of the better-documented examples of a species tracking climate change in real time. It is now a year-round New Hampshire bird in a way that it simply was not for most of the twentieth century. The biology behind that brilliant red plumage - and why it matters to females making mate choices - is worth understanding in more detail at the Northern Cardinal field guide.

The patterns New Hampshire shows - red birds concentrated at elevational or seasonal intersections, with crossbills and grosbeaks governed by cone crops rather than territory - are part of a wider northeastern story. Similar dynamics play out in orange birds in Arkansas and orange birds in Illinois, where the same migratory species appear at different latitudes on the same continental journeys. Understanding one state’s red-bird list makes the others easier to read.
