Iowa Nature Guide: November 2026
November strips Iowa down to its bones — bare timber, brown prairie, and gray skies — but it is also a month of motion: the last great waterfowl flights pour down the flyways, the snow geese pass through, and the wintering eagles return to the rivers. The first snows arrive and the land settles toward winter.
What to look for this week
- Feeders are at their winter peak — chickadees, nuthatches, and cardinals work the seed, while wintering bald eagles already crowd the open water below the Mississippi dams at Keokuk and Le Claire.
- The Quadrantid meteor shower peaks in a short, sharp burst around January 3; watch the northeast after midnight from a dark site like the Loess Hills ridges.
- A planning week — order seeds early and favor the short-season varieties that finish reliably in northern Iowa's cold.
Birds This Month
November is the last surge of fall migration and the return of winter birds in Iowa. The waterfowl flights peak: vast flocks of snow geese and greater white-fronted geese pour down the Missouri flyway, staging by the tens of thousands at western wetlands like Riverton, and Canada geese, mallards, northern pintail, and diving ducks crowd the open water before freeze-up. Tundra swans and late sandhill cranes pass through, and bald eagles gather below the river dams once more.
At the feeders, the winter community reassembles: dark-eyed juncos, American tree sparrows, chickadees, nuthatches, cardinals, and woodpeckers settle in, and in irruption years the first northern finches — redpolls and pine siskins — may appear. Rough-legged hawks arrive from the Arctic to hunt the open fields.
This month's tip: visit a western Iowa wetland during the snow goose peak before freeze-up — the swirling white clouds of geese lifting off the water are one of the state's great wildlife spectacles, and November is the second of the two annual windows to see it.
What's Blooming
The Iowa wildflower season is over by November, ended by the hard freezes. What remains is the prairie's winter structure rather than bloom: the standing skeletons of compass plant, coneflowers, blazing star, and rattlesnake master, and the tawny, rust, and copper seed heads of big bluestem, Indian grass, and little bluestem catching the low light and feeding the winter sparrows and juncos. The last witch hazel flowers finish in the timber early in the month.
In the garden, the season's growth is finished, though a few exceptionally hardy plants — a stray calendula or pansy — may survive into early November in a sheltered spot. This is the season of bare structure: bright red winterberry and the persistent berries of hawthorn and crabapple become the visual interest, glowing against the gray and feeding the roving flocks of robins and waxwings.
Garden This Month
November is the close of the Iowa garden year and the work of putting it to bed. Finish harvesting the frost-hardy crops that keep getting sweeter — kale, Brussels sprouts, carrots, parsnips, and leeks — before the ground freezes hard. Mulch the strawberry bed, garlic, and any marginal perennials once the soil has chilled, which protects them through the freeze-thaw cycles rather than encouraging late growth.
This is the time for the final cleanup and winter protection: wrap the trunks of young fruit and ornamental trees to guard against rabbit and rodent gnawing and winter sunscald, drain and store hoses and irrigation, clean and oil tools before storage, and empty or insulate pots that could crack in the cold. Leave seed heads and ornamental grasses standing for winter interest and wildlife, and apply a final layer of leaves or mulch over beds to insulate the soil for the long winter ahead.
Zone 4b (far north Iowa): the garden is shutting down for winter — finish mulching perennials and bulbs after the ground freezes, wrap young tree trunks against rabbits and sunscald, and make sure tender roots are dug and stored.
Zone 5a (central Iowa): complete the fall cleanup, mulch the strawberry bed and marginal perennials once the soil has chilled, drain irrigation, and harvest the frost-sweetened kale, carrots, and Brussels sprouts that hold in the cold.
Zone 5b (southern Iowa): the mildest tier still has cold-hardy greens producing — harvest spinach, kale, and root crops, finish planting garlic if you haven't, and mulch perennials before the harder freezes set in.
What's at the Farmers Market
November is the transition to Iowa's winter markets as the outdoor season ends and the storage harvest takes over. The durable, cured crops dominate: storage onions, garlic, potatoes, carrots, beets, parsnips, turnips, cabbage, and winter squash that will keep for months. Frost-sweetened kale, Brussels sprouts, spinach, and collards are crisp and at their best, and the last apples and cider remain available.
The holiday-season markets bring cranberries (not Iowa-grown but a seasonal staple), winter squash and pumpkins for the table, honey, eggs, and storage pears, along with cut greens, gourds, and decorative items. Store roots in a cool, humid, dark place and squash somewhere cool and dry, choose firm and heavy specimens that will keep, and use the tender frost greens within a few days while the storage crops hold for the long winter.
Night Sky This Month
November's long, dark, and increasingly cold nights bring the transition from autumn to winter skies over Iowa. The autumn constellations — the great square of Pegasus, Andromeda, and high overhead Cassiopeia — dominate the early evening, while the brilliant winter stars climb in the east: Taurus with the orange eye of Aldebaran and the sparkling Pleiades cluster, followed by Orion rising later in the night.
The Leonid meteor shower peaks in mid-November, usually a modest shower but capable of surprises, best after midnight from a dark site like the Loess Hills. The crisp, dry November air can deliver excellent transparency on clear nights, and the early darkness makes for convenient evening stargazing well before bedtime as the year turns toward its longest nights.
Exact planet positions and this year's Leonid timing vary year to year — the printable Iowa night-sky guide gives the current details for your location.
Butterflies & Pollinators
Butterfly activity has effectively ended in Iowa by November, with the hard freezes and short, cold days ending the season. The summer's species are all in their overwintering forms now, scattered across the dormant landscape. The monarch migration is complete — the long-lived migratory generation that left Iowa in September has reached, or is nearing, the oyamel fir forests of central Mexico, where it will cluster through the winter before its descendants begin the return north next spring.
Iowa's resident butterflies wait out the cold close to home. Mourning cloaks, eastern commas, and question marks hibernate as adults wedged behind loose bark, in woodpiles, and in unheated sheds, protected by the antifreeze compounds in their bodies. The prairie-specialist regal fritillary overwinters as a tiny first-instar caterpillar in the prairie thatch, and other species rest as chrysalises and eggs anchored to dead stems — all waiting, dormant, for the warmth of spring still five months away.
Trees This Month
By November, Iowa's deciduous trees stand bare, the last leaves stripped away by the autumn winds. The structure of the timber is fully revealed: the broad, gnarled crowns of the bur oaks, the shaggy bark of the shagbark hickories, the white-patched bark of sycamores glowing along the streams, and the smooth, sinewy gray trunks of the American hornbeams (blue beech) in the moist southeast ravines. The marcescent young oaks and ironwoods keep their tan, dead leaves, rattling in the wind and standing out in the otherwise bare woods.
The eastern redcedars hold their dark green foliage and their powder-blue cones, the only conifer green across most of the Iowa landscape and a vital winter food and shelter source for birds. The bare trees have dropped their final mast crop, and the timber is now settled into its dormant winter form, awaiting the snow.
