Kansas Nature Guide: December 2026
December settles the Kansas plains into winter — eagles gather at the reservoir dams, geese raft on the central marshes, and the long, dark, clear nights bring the brilliant winter constellations over the cured prairie.
What to look for this week
- Bald eagles gather below the reservoir dams at Clinton, Milford, and Tuttle Creek, fishing the open tailwater as the lakes freeze.
- Order seed now around heat- and drought-tolerant Kansas crops, and plan the windbreak every prairie garden needs.
- The Quadrantid meteor shower peaks around January 3 in a short, sharp burst; look to the northeast after midnight from a dark Flint Hills sky.
- The bare cottonwoods along the creeks hold the conspicuous stick nests of red-tailed hawks against the gray winter sky.
Birds This Month
December is a fine winter birding month in Kansas, and the bald eagle gathering is its highlight. Bald eagles concentrate below the dams of the big reservoirs — Clinton, Milford, Tuttle Creek, Perry, Cheney, and others — and along the open Kansas River, fishing the unfrozen tailwater. The central marshes of Cheyenne Bottoms and Quivira still hold rafts of geese and ducks where the water stays open, and lingering sandhill cranes may pass through early in the month.
The winter specialties are well established. The western high plains hold rough-legged and ferruginous hawks, prairie falcons, northern harriers, and flocks of horned larks and Lapland longspurs over the open country, and irruptive years can bring short-eared owls coursing over the grasslands at dusk. The Christmas Bird Count season is underway statewide.
At feeders and in the brush, the winter mix is full — dark-eyed juncos, American tree sparrows, Harris's sparrows (the Great Plains winter signature), northern cardinals, cedar waxwings, and goldfinches on the standing seed heads. Western meadowlarks flock in the cured grass and flush from the roadsides.
This month's tip: join a local Christmas Bird Count and visit a reservoir dam on a cold morning — the gathered eagles, geese, and wintering ducks are easiest to find in the first hours of light.
What's Blooming
There are no wildflowers blooming in December on the Kansas prairie, but the cured grassland carries the winter's quiet beauty. The tallgrass of the Flint Hills stands in shades of tan, russet, and copper — big bluestem, Indiangrass, and especially little bluestem, which holds a warm wine-red glow on the slopes well into the cold — and a dusting of snow on the cured tallgrass under a low winter sun is one of the loveliest plains scenes.
Beneath the grass, next year is already waiting. The flat green basal rosettes of evening primrose, blazing star, and other prairie plants hug the ground through the cold, and the dark standing seed heads of sunflower, gayfeather, coneflower, and compass plant feed wintering goldfinches and juncos and shelter overwintering insects. The bleached, tumbling skeletons of wild indigo roll along the fence lines in the prairie wind. The Kansas prairie in December is at rest, but full of life held in reserve for the spring.
Garden This Month
December is the planning and protecting month in the Kansas garden, the season at full rest. With the ground frozen for most of the state, the work turns to safeguarding plants against the long, windy plains winter and to planning the year ahead. The prairie wind is the constant threat — it strips mulch, desiccates evergreens and young bark, and drives the cold deep — so check and replace mulch over perennial crowns, garlic, and strawberries, wrap young tree trunks against sunscald and rabbits, and shield evergreens in the exposed west.
This is the time to dream and order. Browse the seed catalogs and plan next year's garden around Kansas's realities — the heat- and drought-tolerant crops (okra, sweet potatoes, southern peas, melons, and tough tomato and pepper varieties), the value of windbreaks and drip irrigation, and an early start on long-season transplants. On the milder days, prune dormant fruit trees and shrubs while their structure is bare and clear. In the milder eastern gardens, cold-frame and low-tunnel greens keep producing on the thaws, a fresh harvest in the dead of the Kansas winter.
Zone 5b (western and north-central Kansas): deep winter, with the coldest temperatures and the harshest wind. Keep mulch over perennial crowns and overwintered garlic, protect young trees and evergreens from the desiccating wind and from rabbit and vole damage, and knock heavy snow gently off evergreens. This is planning time — order seed and design windbreak plantings.
Zone 6a (central Kansas): the dormant heart of winter. Check that wind has not stripped mulch off perennial crowns, garlic, and strawberries, prune dormant deciduous trees and shrubs on the milder days, and protect cold-frame and low-tunnel greens. Browse seed catalogs and plan next year's garden.
Zone 6b–7a (eastern Kansas — Kansas City at 6b, Wichita and the southeast at 7a): the mildest Kansas gardens. Hardy greens — kale, spinach, mache, and tatsoi — survive in cold frames and low tunnels and can be picked on thaws. Prune dormant fruit trees and shrubs, mulch and protect tender perennials, and plan and order seed for the season ahead.
What's at the Farmers Market
December markets in Kansas run on the holiday and winter-storage season, indoors and online as the outdoor markets close. The tables hold the keepers — winter squash, pumpkins, sweet potatoes, potatoes, storage onions, and the cold-sweetened roots (carrots, beets, turnips, parsnips, and rutabagas) — alongside the hardy greens (kale, collards, cabbage, and tunnel spinach) at their sweetest.
Holiday goods carry the season — apples from cold storage, pecans and black walnuts, evergreen wreaths and Christmas trees, and pie pumpkins and squash for holiday baking — and the Kansas pantry staples remain: local honey, eggs, grass-fed beef and pork, sunflower seed, and stone-ground flour and wheat berries from the state's winter wheat. High tunnels keep the fresh greens and microgreens coming.
For selection and storage: keep winter squash, pumpkins, and onions cool, dry, and airy rather than refrigerated, and store sweet potatoes warm and dry. Trim the tops from root crops before refrigerating them for long keeping, store nuts cool and airtight or freeze them, and keep flour and wheat berries airtight in a cool, dark place.
Night Sky This Month
December brings the longest, darkest nights of the year and the brilliant winter sky to Kansas, with the best meteor shower of the season as a bonus. The dark plains skies are at their finest now — the Cimarron National Grassland in the far southwest, Lake Scott State Park, the Wilson and Webster reservoir country, and the open Flint Hills back roads all spread the whole bowl of the cold, transparent sky beneath the wide prairie horizon.
The winter showpieces dominate the evening: brilliant Orion climbs the southeast with the Orion Nebula glowing in his sword, flanked by Taurus, the Pleiades, the twins of Gemini, and the Dog Stars Sirius (the sky's brightest) and Procyon rising behind. The winter Milky Way arches faintly overhead from a truly dark site. The Geminid meteor shower peaks around December 14, the richest and most reliable shower of the year — 100 or more meteors an hour from a dark sky, radiating from Gemini high in the east and good all night, not just after midnight.
Because the planets and the exact Geminid peak shift each year, check the printable Kansas night-sky guide for this year's specific viewing nights and planet visibility from your latitude. Dress warmly for the deep cold, find a dark site, and watch the whole sky for the Geminids.
Butterflies & Pollinators
December is the deepest pause of the Kansas butterfly year, but a few species are present, simply hidden in plain sight. The state's overwintering adults — the mourning cloak, eastern comma, and question mark — pass the cold tucked under loose cottonwood and oak bark, in woodpiles, and in the leaf litter of the creek-bottom gallery woods, and on a freak warm December afternoon a mourning cloak may briefly emerge along a sunlit timbered creek before retreating to shelter.
The rest of Kansas's butterflies wait in other forms. The great regal fritillary of the Flint Hills sleeps as a tiny first-stage caterpillar deep in the unburned tallgrass thatch — the reason winter and spring prairie burns are timed and rotated to spare it. Black swallowtails hang as brown chrysalises on dead stems, and the monarchs that filled the September skies are clustered far south in the Mexican fir forests. Leaving standing grass, leaf litter, and dead stems undisturbed through the winter is the single best thing a Kansas yard can do for them now.
Trees This Month
The Kansas tree year is at full rest in December, and the bones of the gallery forest stand clear along every creek and river. The state tree, the eastern cottonwood, is the bare landmark of the plains — a massive, pale-barked silhouette spreading against the winter sky, its crown often holding the bulky stick nests of red-tailed hawks and the wintering bald eagles, easy to spot now that the leaves are gone.
Along the old field boundaries, the gnarled, thorny Osage orange hedgerows — the 'hedge' planted across Kansas before barbed wire — stand bare, with a few heavy hedge-apples rotting beneath them. The bur oaks hold a scatter of dried russet leaves, the hackberries keep their dark berries for wintering birds, and the dark-barked black walnuts stand bare in the bottoms. Around the farmsteads, the planted eastern redcedar windbreaks stay deep green and berry-laden, sheltering wintering robins, waxwings, and finches and breaking the relentless wind across the cold, open Kansas country.
