Snowy owl reports in Massachusetts this winter

Winter 2026-27 so far

Reading this winter’s reports for Massachusetts from iNaturalist.

Looking up the latest research grade snowy owl report for Massachusetts.

Massachusetts is one of the most reliable snowy owl states in the country, with owls on barrier beaches, salt marsh and airport grassland along the coast in nearly every winter.

Winter by winter

Twelve winters of snowy owls in Massachusetts

Measured against everything birders reported, the biggest winter in the Massachusetts record is 2017-18: 50 research grade reports, 4.0x an ordinary winter. Each winter runs November 1 to March 31, and its rate is snowy owl reports per 10,000 bird reports for the state, so the rising number of people on iNaturalist does not read as more owls.

Research grade snowy owl reports on iNaturalist for Massachusetts, November 1 to March 31, newest winter first. Each bar is the irruption index, the thin line marks 1.0x, an ordinary winter, and the number in brackets is the count of reports.

Where

Where snowy owls winter in Massachusetts

Snowy owls look for country that resembles the tundra: flat, open and treeless, with a low perch to hunt from. In Massachusetts that means:

  • barrier beaches
  • salt marsh
  • airport grassland

“Snowy owls wintering in Massachusetts are typically found in grassland habitat near the coast that resembles their Arctic nesting habitat.”

  • Evening grosbeak

    Large tree seeds, especially box elder and maple, and sunflower at feeders.

    Flights south follow poor seed crops in the boreal forest, and spruce budworm outbreaks in the north have fed a recovery in numbers.

  • Redpoll

    Birch and alder catkins, and nyjer at feeders.

    When the northern birch seed crop fails, flocks come south, and big flights have tended to come every other winter.

  • Pine siskin

    Small conifer seeds, alder and birch, and nyjer at feeders.

    A nomad on conifer seed that settles wherever the cones are good, so it can be abundant one winter and scarce the next.

  • Red crossbill

    Seeds prised from closed conifer cones with a crossed bill.

    Several call types each specialise on different conifers and wander to wherever their cone crop is heavy.

  • White-winged crossbill

    Spruce and tamarack seed.

    Moves south only when the boreal spruce crop fails, so years pass between good winters for it.

  • Pine grosbeak

    Mountain ash berries, crabapples and conifer buds.

    Comes south when the northern fruit crop is poor, often tame and slow moving in ornamental fruit trees.

  • Bohemian waxwing

    Fruit: mountain ash, crabapple, juniper and buckthorn.

    Flocks roam in search of fruit and arrive wherever a heavy crop hangs on into winter.

  • Rough-legged hawk

    Voles and other small rodents, hunted by hovering over open fields.

    A regular winter visitor from the Arctic whose numbers rise and fall with the rodent cycles in its breeding range.

  • Snow bunting

    Weed and grass seed on bare ground.

    Flocks settle on windswept fields and shorelines where snow blows thin, and move on with each storm.

  • Northern shrike

    Voles and small birds, sometimes cached on thorns.

    A songbird that hunts like a small hawk, coming south in larger numbers when prey in the north is scarce.

Watching

How to watch a snowy owl in Massachusetts

  • Keep about 100 yards away. A snowy owl in winter is resting between hunts and every flush costs it energy it may not have. If it turns to stare, stands up or flies, back off. Binoculars, a scope or a long lens close the distance instead.
  • Stay in the car. On farm roads and at airport edges the car works as a blind; an owl that ignores a parked vehicle will leave when a person steps out. Pull fully off the road and keep to public roads outside fences.
  • Let the owl hunt its own food. Baited owls learn to fly low toward people and cars, which draws them onto roads and runways where collisions kill them.
  • Leave the calls at home. Recorded calls and imitations pull owls off their hunting perches and add stress in the hardest season of the year.
  • Share sightings at the state level. An owl that holds one field for weeks draws crowds once its spot is posted; the state and the date are plenty for the record.
