Fall Bird Migration in Montana: Where To Watch

Q: Where are Montana migration counts published?

Bridger Mountains fall count, published Daily through the fall season, reported to HawkCount. A count is a reading of one day at one place, and the totals can double or halve between one week and the next as fronts pass, so the trend across the season is the useful reading rather than any single figure. The count page is linked from this page.

Where to stand

Public viewing sites in Montana

Every place below is one an agency itself describes for watching the fall passage, with the agency named and linked, the species it documents there, the months it names as the peak, and the facility that exists: a tour route, a platform, a tower, a visitor centre. Where the agency wrote a sentence worth reading, it is quoted exactly.

The refuge dates its tundra swans to the day rather than the season, putting their return from the Alaskan breeding grounds late in September and their departure in mid to late November. Most visitors work the 15 mile auto tour route.

“They leave their breeding grounds in Alaska early fall and appear again at Bowdoin Refuge late in September and stay through mid to late November.”

The count runs from late August to the end of October. Sharp-shinned hawks average several hundred a season and broad-wingeds a couple of dozen, but the flyway is known for golden eagles, and the Bridger Raptor Festival falls inside the season.

“The Bridger Mountains site lies within the Gallatin National Forest on the east slope of the mountain range, about 25 km north of Bozeman and 3 km north of Saddle Peak.”

The season runs from late August into the first week of November. Sharp-shinned hawks are the volume bird here, averaging over 1,500 a season against a few dozen broad-wingeds, and the site sits high enough that the weather sets the day.

Before you drive out to Montana

Viewing in Montana is run by U.S. Fish and Wildlife Service, Bowdoin National Wildlife Refuge, whose own page is the one to read the night before.

That page carries the current picture: whether the auto tour route or platform is open, which units are closed for the season, festival dates, and where the agency counts birds, this week’s count.

Never assume a bird. Cranes, geese and swans move with the weather, so a staging area that held thousands on Tuesday can be nearly empty on Saturday after a front passes, and a warm autumn holds birds to the north for weeks. Never assume access either: a refuge road can be gated, flooded or closed for a unit without notice. Check with the agency before you travel, and stay on the platform, road or tour route it designates when you get there.

The map

Montana sites, refuges and the reporting record

Viewing sites in Montana, with the national wildlife refuges in the state drawn underneath. The coloured grid is where people have uploaded a verified sandhill crane record to iNaturalist in September, October, November and December, brighter where more have been logged. It is a map of reports rather than of birds: it thickens around refuges, car parks and towns because that is where observers stand, and it shows past reports rather than birds present today. Pins are public viewing sites an agency itself describes; grey dots are US Fish and Wildlife Service refuges and hatcheries, drawn because the refuge system is where most of the staging happens.

When

When the passage peaks in Montana

U.S. Fish and Wildlife Service, Bowdoin National Wildlife Refuge puts the Montana peak at Late September through mid or late November for the swans at Bowdoin, and late August through October on the Bridger ridge. That describes a pattern across past autumns. The week itself swings with the weather: a cold front to the north moves cranes and geese south in a single night, and a warm spell holds them for weeks. Dawn and the last hour before dusk are when cranes and geese move between the fields and the water, and that movement is the spectacle the platforms are built for.

Montana runs two autumns at once, several hundred miles apart. On the Hi-Line, Bowdoin dates its tundra swans to the day rather than the season: down from the Alaskan breeding grounds late in September, gone by mid to late November, seen from a 15 mile auto tour route east of Malta. Along the mountain fronts, the raptors move. The Bridger count works a ridge in the Gallatin National Forest above the ski area north of Bozeman, on a flyway known for the largest concentration of golden eagles in the lower 48, and Jewel Basin works the flank of Mount Aeneas over the Flathead Valley, where sharp-shinned hawks average over 1,500 a season.

Below, one curve per species the agencies document in Montana: every research grade observation members of the public have uploaded to iNaturalist for the state, by calendar month across every year the platform holds, with September to December shaded. Counts of uploads, so they measure observers as well as birds, and the shape is worth reading where the absolute numbers are not.

Tundra swan

124 research grade tundra swans observations have been uploaded to iNaturalist for Montana across every year the platform holds, and 40 percent of them fall in the four shaded autumn months. The busiest month in the record is March. An autumn month carries about 1.31 times as many uploads as an average month outside autumn. People upload most of everything in July, so a bar that rises after that is the stronger signal. Counts of what people reported, measuring observers as well as birds. See the autumn records.

Broad-winged hawk

19 research grade broad-winged hawks observations have been uploaded to iNaturalist for Montana across every year the platform holds, and 16 percent of them fall in the four shaded autumn months. With fewer than 60 records the series is too thin to summarise, so the bars stand on their own. Counts of what people reported, measuring observers as well as birds. See the autumn records.

Sharp-shinned hawk

227 research grade sharp-shinned hawks observations have been uploaded to iNaturalist for Montana across every year the platform holds, and 41 percent of them fall in the four shaded autumn months. The busiest month in the record is January. An autumn month carries about 1.36 times as many uploads as an average month outside autumn. People upload most of everything in July, so a bar that rises after that is the stronger signal. Counts of what people reported, measuring observers as well as birds. See the autumn records.

The movement is watched from the designated pullout or platform: the birds settle on shallow water for the night, and the roost itself is the one place a viewing site is never placed. “Sandhill cranes flying over Sherburne National Wildlife Refuge (24542820818)” by USFWS Midwest Region from United States, CC BY 2.0

Latest reports

What people have reported in Montana lately

The most recent research grade autumn observation of each species that anyone has uploaded to iNaturalist for Montana, as a date and the platform’s own coarse locality. Evidence that people do find tundra swan and broad-winged hawk here. Each is one bird on one past day: the flocks move with the weather, so where they are this week is what the agency page and its counts answer.

Questions about Montana

Where can I watch fall migration in Montana?

Montana has 3 agency designated viewing sites in this inventory, 1 of them on federal land: Bowdoin National Wildlife Refuge, Bridger Mountains hawk count and Jewel Basin hawk count. Every one is a place U.S. Fish and Wildlife Service, Bowdoin National Wildlife Refuge or another public agency itself describes for wildlife viewing, listed above with the facility that exists there, the months the agency names and a link to the agency page. Montana runs two autumns at once: tundra swans down from Alaska onto the Hi-Line wetlands from late September, and raptors along the mountain fronts, where one count sits above a ski area north of Bozeman.

When is the fall migration peak in Montana?

U.S. Fish and Wildlife Service, Bowdoin National Wildlife Refuge puts the Montana peak at Late September through mid or late November for the swans at Bowdoin, and late August through October on the Bridger ridge. That describes a pattern across past autumns, and the week itself swings with the weather: a cold front to the north moves cranes and geese south in a single night, and a warm spell holds them for weeks. The months named site by site above are the agency's own for each place, and the agency page carries what it says about this season.

Which species are documented at the Montana sites?

Tundra swans at 1 site, broad-winged hawks at 2 sites and sharp-shinned hawks at 2 sites. The species listed for each site are the ones the agency itself documents there in the fall, so a site may hold other migrants the agency page happens to leave out. The month curves further down show when people have reported each of these species in Montana, as a count of uploads to iNaturalist across every year the platform holds.

Will I definitely see tundra swans in Montana?

A sighting is never certain. Migrating birds move with weather fronts, so a staging area that held thousands on Tuesday can be nearly empty on Saturday after a front passes, and a warm autumn holds birds to the north for weeks. The sites above are the places where an agency has recorded enough birds often enough to build viewing provision, which is the best odds available anywhere. Arrive at first light or in the last hour before dusk, when cranes and geese move between the fields and the water, bring more magnification than you think you need, and stay on the platform, road or tour route the agency designates.

Who publishes current conditions for Montana?

U.S. Fish and Wildlife Service, Bowdoin National Wildlife Refuge, linked from the note on this page and from each site above. Its pages carry the things that change: refuge road and auto tour status, seasonal closures of units, festival dates, and in several states a dated crane or goose count from the refuge staff. Those change faster than any third party page can follow, so the agency page is the one to read before you travel.
