December brings deep winter to Nebraska — short days, hard cold, and snow blowing across the open plains and Sandhills. The nature that remains is concentrated and resilient: wintering eagles and raptors, feeder flocks, and the long, dark, brilliant nights of the year's best stargazing.
Week by week in December
December 3–9
- Bald eagles concentrate at unfrozen tailwaters below the dams and power-plant outlets, fishing through the deepening cold.
- Long, dark December nights and cold, clear Plains air make the Sandhills around Valentine the year's best winter stargazing country.
- Storage onions, garlic, potatoes, and winter squash carry the holiday season at indoor and on-farm markets.
December 10–16
- The Geminid meteor shower, one of the best of the year, peaks around December 14 — dozens of bright meteors an hour from a dark Sandhills site.
- Christmas Bird Count season begins, tallying wintering eagles, raptors, and feeder birds across Nebraska.
- Young bur oaks hold their russet marcescent leaves as the bare cottonwoods stand stark against the winter sky.
December 17–23
- The winter solstice near December 21 marks the year's longest night as Orion, the Pleiades, and the full Winter Hexagon blaze overhead.
- Prairie falcons hunt the western grasslands and snowy owls may appear on open farmland in irruption years.
- A planning week by the fire — order seeds, plan next year's beds, and prune oaks on a calm day during their safe dormant window.
December 24–31
- The year closes with eagles at open water, rough-legged hawks over snowy fields, and feeder flocks of chickadees, nuthatches, and cardinals.
- Mourning cloaks and anglewings sleep behind cottonwood bark and in woodpiles along the river timber, loaded with antifreeze to survive the deep cold.
- The panhandle ponderosa pines of the Pine Ridge stand dark and green through the cold — a green island in the bleached winter prairie.
Birds This Month
December birding in Nebraska is winter birding — open country and the feeder. Bald eagles are a highlight, gathering by the dozens at open water below the Platte River dams and around Lake McConaughy, Kingsley Dam below it, and the Sutherland (Gerald Gentleman) power-plant outlet, fishing the unfrozen tailwaters through the cold. Rough-legged hawks from the Arctic hover over snowy fields, northern harriers course the marshes, and prairie falcons hunt the western grasslands.
At the feeder, black-capped chickadees, white-breasted and red-breasted nuthatches, downy and hairy woodpeckers, northern cardinals, dark-eyed juncos, and American tree sparrows work the seed, with Harris's sparrows in the brush. In irruption years, common redpolls, pine siskins, and even snowy owls appear, and Lapland longspurs and horned larks flock on the bare farmland. December is also Christmas Bird Count season, when counts across the state tally the wintering birds.
This month's tip: dress warm and visit open water below a dam for the wintering bald eagles, and keep feeders full and a heated birdbath open through the deep cold.
What's Blooming
Nothing blooms outdoors in a Nebraska December. The prairie and Sandhills lie frozen and snow-scoured, and the wildflower year is months from returning. What the season offers is structure and seed: the bleached, rattling stalks of compass plant, coneflower, and blazing star standing above the snow, the seed heads of goldenrod — the state flower — gone to fluff, and the copper of little bluestem holding color through early winter. The bright red stems of red-osier dogwood glow in the wet draws, and the powder-blue cones of female eastern redcedars and the dark drupes of hackberry feed wintering robins, waxwings, and bluebirds. Indoors, this is the heart of amaryllis, paperwhite, poinsettia, and holiday-greenery season, and the start of the catalog-dreaming weeks when Nebraska gardeners plan next year's beds while the ground lies hard and frozen.
Garden This Month
December gardening in Nebraska happens indoors and on paper. The beds are frozen and often snow-covered statewide, so this is a planning month: order seeds and plan next year's vegetable rows and prairie plantings, inventory leftover seed and test it for germination, and check stored dahlia tubers, canna roots, and squash for rot. It is the safe dormant window to prune oaks — while the beetles that spread oak wilt are inactive — and to prune apple and pear trees on a mild, calm day.
Outdoors, the work is protection. Leave snow where it falls over perennial beds and the strawberry patch — it is the best insulation a Nebraska garden gets on its often-snowless open ground, holding soil temperatures steady against the brutal freeze-thaw cycles. Knock heavy, wet snow gently off arborvitae and juniper branches to prevent breakage, but leave dry snow undisturbed. Check that young-tree trunk wraps and rabbit guards are in place, and recycle the holiday tree as a brush shelter for wintering birds when the season ends.
Zone 4b (Sandhills and panhandle): the garden is fully dormant in the coldest corner of the state — leave snow as insulation over crowns, check that young trees are wrapped against sun-scald and wildlife, and confine the work to planning and seed-ordering by the fire.
Zone 5a (central Nebraska): nothing to plant — inventory and order seeds, sharpen and oil tools, and confirm mulch and any snow are protecting bulbs, garlic, and marginal perennials through the freeze-thaw swings of a Platte Valley winter.
Zone 5b (southeast, lower Missouri Valley): the mildest tier is still deep-frozen — focus on planning and on pruning oaks during their safe dormant window on a calm day, and check stored tubers and bulbs for rot.
What's at the Farmers Market
December markets in Nebraska are the indoor and storage season at its quietest. Holiday markets in Omaha, Lincoln, and the larger towns and on-farm storage stands carry the durable cured harvest: storage onions, garlic, potatoes, carrots, beets, parsnips, cabbage, and winter squash that keep for months, along with the last apples from cold storage.
The strength of the month is the pantry, freezer, and holiday table — honey, jams, pickles, and canned goods from summer, grass-fed Sandhills beef and pork from ranch freezers, farm eggs, and holiday turkeys, wreaths, and greenery. A few growers running heated hoop houses bring tender spinach, mâche, and overwintered greens to indoor markets. Keep storage roots cool and humid, onions, garlic, and squash cool and dry, and the fall harvest will carry through the deepest part of the Nebraska winter.
Night Sky This Month
December gives Nebraska its longest nights and the year's best winter stargazing, the cold, dry air exceptionally clear. The state's darkest skies are the Sandhills around Valentine and Merritt Reservoir, the Niobrara valley, and the panhandle's Wildcat Hills and Lake McConaughy, where the brilliant winter sky blazes far from any city glow.
The winter solstice near December 21 marks the shortest day. After dark, Orion climbs in the southeast with Sirius, the Pleiades and orange Aldebaran in Taurus, the twins of Gemini, and the full Winter Hexagon rising — the richest sky of the year. The Geminid meteor shower, one of the best and most reliable of all, peaks around December 14, throwing dozens of bright meteors an hour from a dark Sandhills site, and the minor Ursids follow near the solstice.

Butterflies & Pollinators
No butterflies fly in a Nebraska December — the prairie lies frozen and wind-scoured, and the season's species are deep in their overwintering forms scattered across the landscape. Monarchs are far to the south, clustered in the oyamel fir forests of central Mexico. Nebraska's resident butterflies wait out the cold in hidden, dormant states: the mourning cloak, eastern comma, and question mark survive as adults wedged behind loose cottonwood and elm bark, in woodpiles, and under brush along the Platte and Missouri timber, kept alive through deep cold by the glycerol antifreeze in their bodies.
The prairie-specialist regal fritillary sleeps as a tiny first-instar caterpillar buried in the Sandhills and tallgrass prairie thatch, waiting for spring to wake its violet host plants. The black and eastern tiger swallowtails overwinter as chrysalises fixed to stems and bark, the hairstreaks as eggs and chrysalises in the leaf litter. This is the season to plan a butterfly garden of native milkweed, prairie clover, blazing star, and aster — and to leave the leaf litter and standing stems undisturbed, since they shelter next year's butterflies through the winter.

Trees This Month
Nebraska's trees are fully dormant in December, and winter reveals their forms most clearly. Along the Platte, Missouri, Niobrara, and Republican, the massive eastern cottonwoods, the state tree, show their towering bare silhouettes, the pale gray bark deeply furrowed and the wide crowns stark against the winter sky. The green ashes, hackberries, and silver maples of the bottomlands stand bare beside them.
On the dry bluffs and savanna remnants the bur oaks spread their corky, wide-branched winter crowns, some young trees still holding russet marcescent leaves that rattle in the wind. The dark eastern redcedars in the draws and fencerows hold the only true green in eastern Nebraska's winter timber, their powder-blue cones drawing waxwings and robins. In the panhandle, the ponderosa pines of the Pine Ridge and Wildcat Hills keep their long dark needles through the cold — the westernmost forest in the state, and a green island in the bleached winter prairie.
