Iowa Nature Guide: February 2026
February is still deep winter in Iowa, but the light is returning and the first stirrings of the season begin: great horned owls nesting, cardinals singing at dawn, and — in the south — the leading edge of the spectacular snow goose migration up the Missouri flyway. The cold, clear nights make for some of the year's best stargazing.
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
February brings the first real motion to Iowa's bird year. Feeder regulars — chickadees, nuthatches, cardinals, woodpeckers, and juncos — are joined by lengthening days that switch on song: northern cardinals whistle from the treetops at dawn, and black-capped chickadees begin their clear two-note 'fee-bee.' Great horned owls are already on eggs, the females incubating through subzero nights; listen for pairs hooting back and forth at dusk.
Late in the month, the south end of the state catches the front edge of one of the continent's great waterfowl spectacles: snow geese and greater white-fronted geese push north up the Missouri flyway, with huge flocks staging at Riverton Wildlife Area and along the river bottoms. Bald eagles still crowd the open water below the Mississippi dams, now beginning courtship flights over their nests.
This month's tip: a late-February warm spell can trigger heavy goose movement overnight — check refuge reports and listen for the rolling, high yelping of snow geese passing over after dark.
What's Blooming
Iowa's outdoor landscape is still locked in winter through February, with frozen ground and no wildflowers yet. The earliest signs of life are subtle and worth watching for: the swelling buds of silver maple and red maple along the river bottoms, which will be the first native trees to flower, and the fattening catkins on pussy willows in wet ditches, their silver-gray fur emerging on the warmest days near month's end. In town, hardy snowdrops may push through thawing soil in sheltered, south-facing beds in the milder southern counties. Indoors, this is the height of seed-starting and houseplant-tending season, and gardeners watch the strengthening late-winter light lengthen day by day on the windowsill.
Garden This Month
February is when the Iowa garden year truly begins — indoors, under lights. Start the slowest crops now: onions, leeks, and celery need a long head start to size up before transplanting. Set up the grow-light shelf, refresh seed-starting mix, and sow these first while you wait out the cold. It remains a safe window to finish dormant pruning of apple and pear trees and to prune oaks before spring beetle activity resumes.
Outdoors, leave snow as insulation over perennials, but watch for the freeze-thaw heaving that can push shallow-rooted plants and fall-set bulbs out of the soil; gently firm them back and re-mulch on a thaw. Resist the urge to uncover beds early — Iowa's late-winter warm spells are reliably followed by another hard freeze, and premature growth is the most common winter loss in a garden here.
Zone 5a (central Iowa): start onions, leeks, and celery indoors under lights now — they are the slowest crops and need the head start. Continue dormant pruning of apples and pears on a mild day, and keep checking that snow cover hasn't been stripped from perennial beds in the wind.
Zone 5b (southern Iowa): the southern tier warms first; sow onions and leeks indoors early in the month, and on a thawed day you can prune fruit trees and cut back ornamental grasses before new growth begins.
Zone 6a (far southeast Iowa): the state's mildest corner — late in the month, hardy greens like spinach and peas can sometimes be direct-sown in a thawed, raised bed under a cover, and dormant pruning should be wrapped up before buds swell.
What's at the Farmers Market
Iowa's winter markets and storage stands carry on through February with the same durable harvest: storage onions, potatoes, carrots, beets, parsnips, cabbage, and winter squash, all cured in fall and still in good eating shape. Stored apples are softening a little now but remain available, best used for cooking late in the season.
This is also the tail end of one distinctly seasonal Iowa product: maple syrup. In the southeast and along the eastern river bluffs, sugar maples can begin running sap during late-February thaws, and the first jars of the new season's syrup start appearing at winter markets. Look as well for honey, eggs, frozen meats, and the cold-hardy greens — spinach, kale, and mâche — that overwintering hoop-house growers bring to market. Keep roots cool and humid and squash cool and dry to stretch them toward spring.
Night Sky This Month
February offers Iowa some of its finest stargazing — long nights, dry air, and steady skies, without January's most brutal cold. The Winter Hexagon still fills the southern sky: Sirius, Procyon, Pollux and Castor, Capella, Aldebaran, and Rigel ring the heart of the heavens. In the middle of it, the Orion Nebula glows as a fuzzy patch in the hunter's sword — a fine target for binoculars even from a backyard.
As the evening grows late, the faint, hazy swarm of the Beehive Cluster in Cancer rises in the east between Gemini and Leo, signaling the slow turn toward spring constellations. From a dark site like the ridgetops of the Loess Hills, the winter Milky Way remains visible arching overhead through Auriga.

Butterflies & Pollinators
February is still too cold for any butterfly activity in Iowa, and the prairie remains brown and frozen. The state's butterflies continue to wait out winter in their dormant forms. Monarchs are still overwintering in the Mexican mountains, not yet beginning the multi-generation journey that will eventually return their descendants to Iowa's milkweed in May. Mourning cloaks and the occasional eastern comma and question mark persist as adults sheltered in bark crevices, woodpiles, and unheated outbuildings, their bodies protected by cryoprotectant compounds that keep their tissues from freezing solid. Other species rest as chrysalises anchored to dead stems or as eggs and tiny caterpillars buried in the prairie thatch and leaf litter. A rare February thaw might rouse a single mourning cloak to bask in the sun for an hour, but the true butterfly season is still a month or more away.
Trees This Month
Iowa's trees remain dormant in February, but change is beginning beneath the bark. The river-bottom silver maples and red maples are the first to stir, their flower buds swelling toward the earliest tree bloom of the year. Along eastern Iowa's bluffs and ravines, sugar maples begin moving sap during late-month thaws, the freeze-at-night, thaw-by-day cycle that drives the brief maple-syrup season.
The bare structure of the timber is still on full display: the broad, gnarled crowns of bur oak, the shaggy bark of shagbark hickory, and the smooth, sinewy gray trunks of American hornbeam (blue beech, or musclewood) in the moist ravines of the far southeast. Watch the pussy willows in wet ditches and along stream edges, where the soft silver catkins emerge first and signal that the long dormancy is finally loosening its grip.
