What to look for in nature in Montana this March

When do snow geese and tundra swans fill Freezout Lake in March?

• The big days, usually in late March

  Early March into April; FWP staff have pointed to the last week or so of March as the usual best window · Freezout Lake Wildlife Management Area, U.S. Highway 89 near Fairfield

  When the 2026 migration got going, an FWP wildlife biologist told KXLF that the last seven to ten days of March are usually the best time to plan a visit, and that snow goose numbers that spring were close to double the normal for the date after a mild winter. Weather can shift the whole schedule. A U.S. Department of Agriculture photo caption from April 2018 notes that late snow and ice farther north held unusually large numbers of swans in north-central Montana. For the best light and activity, FWP’s advice, as reported by KXLF, is to come in early morning or late afternoon, since the birds feed in nearby fields through the middle of the day. Stay on the designated roads and pullouts, and do not stop on a road shoulder to watch; local reporting from 2026 listed that as a traffic hazard.

• The Wild Wings Festival in Choteau

  March 19 to 21, 2027, according to the organizer · Choteau, with guided tours out to Freezout Lake

  The festival’s own website gives March 19 to 21, 2027, and says the program will be posted in late 2026 or early 2027, so check it before you plan around any single event. The 2026 schedule is a fair guide to the style: a photography workshop, an evening meet-and-greet with food trucks and conservation booths, a showing of the film “Flight of the Swans,” free guided morning tours of the lake, and a talk by the head of the Raptor View Research Institute on eagles captured along the Rocky Mountain Front. In 2026 most events were free and held at the Choteau Pavilion, with the film at the Roxy Theatre.

• Pintails, mallards and swans at Benton Lake

  From about mid-March, as the ice leaves · Benton Lake National Wildlife Refuge, 12 miles north of Great Falls

  According to the refuge, large numbers of pintails, mallards and tundra swans appear at Benton Lake from mid-March, once ice leaves the shallow marsh and runoff collects. Snow geese turn up too, in flocks of a few hundred to a few thousand that linger a week or longer, and bald eagles and peregrine falcons often appear nearby. The refuge’s nine-mile Prairie Marsh Wildlife Drive is a gravel road open year-round in daylight hours, though bad weather can close it.

Where can you watch sharp-tailed grouse dance in Montana in March?

• Sharp-tailed grouse on the open prairie

  At first light, March into early April · Native grassland and public prairie; ask the local FWP biologist about active leks

  FWP’s advice is to arrive before sunrise, park at least 100 yards from the birds, watch from your vehicle or a small portable blind, and never let a dog chase birds on or near a lek. Active sites show up at dawn as a cluster of birds on bare ground. If you stumble onto a lek, back away quietly rather than creeping closer for a better angle.

• The Grouse House at Benton Lake

  By lottery, usually Thursday through Sunday from the last weekend of March to the middle weekend of May; check the refuge for 2027 dates · Benton Lake National Wildlife Refuge, 12 miles north of Great Falls

  The refuge runs a free viewing blind, nicknamed the Grouse House, that seats six on folding chairs and has room for ten. Access is by lottery, entered by emailing the refuge your contact details and top three dates; in past years the entry deadline fell in the last days of March, and the refuge posts each year’s date itself. The lek was first noticed in 1988 with 12 males, and visitors have reported seeing 45 to 70 dancers. On the refuge’s activities page you can also watch a live camera on the same lek, best, the refuge says, first thing in the morning.

• Greater sage-grouse leks

  Spring dawns; follow FWP’s viewing guidelines · Sagebrush country, mostly on private and public rangeland

  Greater sage-grouse also gather at dawn on leks, where males strut with fanned tails and make popping sounds with their inflated air sacs. FWP publishes Recreational Viewing Guidelines for these birds and lists habitat loss, mainly from converting native shrub-steppe to cropland and from new energy development, as the main threat. Watch from a car, keep your distance, and skip roads that are muddy.

Which birds return to Montana in March, and which wait for April?

• Mountain bluebirds on the fence posts

  Bozeman-area spring migration, usually March 15 to April 25; nesting records run April 5 to June 25 · Open sagebrush, grassland and aspen country; roadside nest-box trails

  A Bozeman-area writer in 2015 put the arrival of mountain bluebirds at mid-March through early April. In the early 1970s Montanans began nailing nest boxes to fence posts, and volunteers with Mountain Bluebird Trails have since placed more than 8,000 nesting structures, usually five or more boxes roughly 100 to 300 yards apart along roads. A 2014 FWP magazine article reports that in western Montana valleys the western bluebird, rusty-chested rather than all sky-blue, has largely replaced the mountain bluebird at those boxes, so the bird on a valley post may be either. If you plan to put up a box, March is the time to have it ready.

• Golden eagles heading north

  Late February to May; at one Alberta watch, heaviest from mid-March into early April · Along the Rocky Mountain Front and other ranges; Montana Audubon is scouting a spring watch near Ramsay, west of Butte

  FWP describes an “eagle highway” along the Rocky Mountain Front from Glacier to Yellowstone, and notes that a tracked eagle used a different route in spring than in fall. The Rocky Mountain Eagle Research Foundation, which counts eagles at a site in Alberta, says the first golden eagles go north in late February and that the peak lasts from mid-March to the first week of April, with the flight over by mid-May. Those are Alberta dates, and timing shifts with weather and place. Montana Audubon, scouting for a reliable spring hawk watch, says raptors move north across Montana from late March to early May. Its first counts near Ramsay on March 31 and April 1 found very few birds, which it blamed on cold, windy weather and being well before peak, so it planned a return in late April; its best count so far was five golden eagles among other hawks on April 23, 2021.

• What waits for April and May

  Cranes in mid-April; ospreys in late April to early May; warblers in mid-May · Wet meadows, river valleys and mountain streams

  The Field Guide gives April 15 to May 12 as spring migration for sandhill cranes around Bozeman and mid-April for large flocks in northeastern Montana, so a crane in March would be an early scout. A Bozeman-area bird guide puts osprey arrival in late April to early May and the first yellow warblers in mid-May. March is the month to learn calls and clear nest boxes so the rush finds you ready.

What wakes up in Montana in March: ground squirrels, frogs and the first wildflower?

• Richardson’s ground squirrels

  Between February and April, depending on elevation and weather; males first, females 10 to 14 days later · Prairie, hayfields and refuge roads in the eastern two-thirds of the state

  The Montana Department of Agriculture says Richardson’s ground squirrels leave hibernation between February and April and that mated females give birth to a single litter in April or May. The Field Guide adds that females typically mate three to five days after emerging. Benton Lake’s staff list them among the spring sights on refuge roads and in the fields.

• Columbian ground squirrels

  Late March and early April in most areas; south-facing slopes can wake one to three weeks before north-facing ones · Western Montana meadows, hillsides and campgrounds

  These larger squirrels come out later. According to the state agriculture department, males appear one to two weeks ahead of females, and breeding begins shortly after the females emerge and lasts about two weeks. Where you see the first one depends on snow cover, soil temperature and the slope you are standing on.

• Columbia spotted frogs in the meltwater

  Breeding from mid-March to mid-June, depending on snowmelt, temperature and elevation · Ponds, springs, beaver ponds and wet meadows in western Montana mountains and valleys

  The Field Guide calls the Columbia spotted frog the most common frog in the mountains and mountain valleys of western Montana. Females lay grapefruit-sized, globular egg masses in shallow water at the margins of ponds, often alongside many other females’ masses. Montana’s other early-spring singers keep later hours: the boreal chorus frog breeds from late April to June, and the Sierran treefrog in April and May, so the full spring chorus is an April story.

• Sagebrush buttercup

  Usually March and April, sometimes as early as February · Sagebrush flats, grasslands and open woods at low and middle elevations

  The Field Guide calls this bright yellow, shiny-petaled flower one of Montana’s earliest bloomers. A native plant column in the Great Falls Gazette describes it as widespread, especially in the western half of the state, and mostly a low-elevation plant, though it can be found above six thousand feet. It stands only half a foot tall at most, so get low.

When do Montana’s grizzly bears leave their dens?

• The first males out

  March and April · Greater Yellowstone, Glacier and the other grizzly ranges of western Montana

  The Fish and Wildlife Service’s spring advisory, issued April 1, 2024 for Montana, Wyoming, Idaho and Washington, says male grizzlies typically leave their dens in March and April and females with cubs appear in April and May. A March 2019 Glacier National Park release reported bear tracks in the snow and said both grizzly and black bears live and travel in the park.

• Food comes first

  As soon as they are out · Low valleys, river bottoms and wherever winter-killed animals lie

  Glacier’s release says the bears are hungry and look especially for carcasses of winter-killed animals. FWP notes that both grizzlies and black bears are opportunistic feeders on roots, grasses, insects, small mammals, fish and carrion. A carcass is a bear’s property, and bears defend it, so scavengers circling a draw are a reason to turn around.

• Cubs wait until April or May

  April and May · Denning country; mothers move cautiously with newborns

  FWP says females give birth in the den and nurse through the whole five to six months without eating or drinking; twin cubs are more common than singles. A mother with cubs is the most protective bear you can meet, which is why the agencies stress noise, groups and bear spray from the first warm days.

What is open in Yellowstone and Glacier in March 2027?

• Yellowstone’s year-round road

  All year; check conditions before you go · North Entrance at Gardiner through Mammoth Hot Springs and Tower Junction to the Northeast Entrance at Cooke City, via the Lamar Valley

  The National Park Service says this is the only road in Yellowstone generally open all year to regular vehicles. From it you can scan the northern range for bison, elk and, with a spotting scope and patience, wolves. Park rules call for staying at least 100 yards from bears, wolves and cougars and at least 25 yards from all other animals, including bison and elk, and the safest view is often from inside the car.

• Oversnow travel ends in mid-March

  Mammoth to Norris through March 7; Norris to Madison, Canyon Village and the Washburn overlook through March 9; Canyon to Fishing Bridge through March 14; the West, South and East entrances and remaining groomed roads through March 15, 2027 · Interior roads of Yellowstone, open only to guided snowmobiles and snowcoaches

  These are the Park Service’s posted 2026–27 oversnow dates (travel begins December 15, 2026), and it warns that all dates can change with weather. Wheeled-vehicle opening dates for 2027 were still unposted in October 2026; the 2026 schedule began April 17, so check the park roads page in spring.

• Glacier’s plows start on the east side

  Road clearing begins in late March on the east side; most roads open by mid-to-late May · Glacier National Park; Apgar and St. Mary campgrounds stay open year-round

  The park says lower-elevation trails usually melt out by the end of April, while mid- and high-elevation trails are generally under snow and some do not clear until late July. Plowing the Going-to-the-Sun Road takes two and a half to three months by the park’s account, so an opening date over Logan Pass cannot be known in March. Most visitor services reopen from late May to early June.

What can you see in Montana’s night sky in March 2027?

• The Worm Moon

  Look east at dusk on Sunday, March 21; the Moon is full before dawn on March 22 · Anywhere with a clear eastern horizon

  Tradition names this full moon the Worm Moon. Full comes at 4:44 a.m. MDT on Monday the 22nd, so Sunday evening, the 21st, gives the best rising Moon, over prairie and peaks alike. The disk looks round for a night either side, and moonlight drowns faint stars, so the darkest skies come near the new moon of the 8th.

• Mercury before dawn

  Farthest from the Sun on the night of March 16 to 17; easiest to catch from about March 8 to 25 · Low in the east-southeast, before sunrise

  The planet reaches its widest morning separation, 27.6 degrees west of the Sun, at 4:20 UTC on March 17, which is the night of the 16th in Montana. The angle is shallow for northern observers, so find a clear, flat east-southeast horizon and bring binoculars; dazzling Venus floats far above it. SeaSky’s calendar calls it the best time to see Mercury in the morning sky.

• Jupiter, the Moon and Mars

  The Moon sits beside Jupiter on March 18 and 19; Mars lies about four degrees from Jupiter around the 30th and 31st (our calculation) · High in the east and south after dusk

  Jupiter stays in the evening sky all spring. By our own calculation, the Moon, about 88 percent lit, slides past the planet at under a degree on the 19th, and around the 30th and 31st Mars and Jupiter stand roughly four degrees apart, high in the sky around 8 p.m. MDT. By the same calculation the thin waning crescent sits near Venus before dawn on March 4 and 5, still in standard time.

• Daylight time begins

  Sunday, March 14, 2027, at 2 a.m. · All of Montana

  Federal law sets daylight time to begin at 2 a.m. on the second Sunday in March, which falls on March 14 in 2027. Dawn bird walks and owl evenings both shift an hour on the clock, so give your body a few days.

• Northern lights

  Any clear, dark night; March is statistically active · Open northern horizons, away from town lights

  Northern lights can show on any clear night, and magnetic storms tend to bunch up near the equinoxes. NOAA’s Space Weather Prediction Center publishes a short-term aurora forecast, and its predicted-cycle chart shows the monthly sunspot count near 86 for March 2027, down from the cycle’s peak. That is general background, not a forecast for any one night.

What can Montana families do outside in March 2027?

• Wild Wings Festival, Choteau

  March 19 to 21, 2027 · Choteau Pavilion and Freezout Lake

  This is the date posted by the festival’s organizers; they say the schedule will go up later. Children do well on the dawn goose tours if they bring snacks and a thermos, since most of the best action is in the cold hour after sunrise.

• Watch the Grouse House on camera

  Early morning, late March to May · Benton Lake National Wildlife Refuge’s website

  If you cannot get a seat in the blind, the live video link on the refuge’s activities page puts the lek on your screen, and the refuge says the best time to catch the dancers is first thing in the morning.

• Join Project FeederWatch while it lasts

  Through April 30 · Any window, yard or park

  The Cornell Lab’s feeder count runs from November 1 to April 30 and is flexible: count as often or as little as you like. U.S. residents pay $18 a year. Remember to take feeders down once bears are out.

• Start a NestWatch card

  Whenever nests are active; check the project site · Backyard boxes and fence-post bluebird trails

  NestWatch, another Cornell Lab project, welcomes anyone. Clean and mount your box this month, then log what you see; the website and mobile app both take reports.

• Programs in Missoula and Billings

  Check the calendars; no March 2027 events were posted yet · Montana Natural History Center, Missoula; Montana Audubon Center, Billings

  Both centers list their upcoming programs online and update them throughout the year. The Audubon Center’s calendar showed only an October bat program when this page was written.

• Log your sightings with Journey North

  All spring · Online

  On Journey North you can post what you see and browse maps of other people’s reports; a bluebird or a first robin makes a good entry.
