Fall Bird Migration in Idaho: Where To Watch

Q: Where are Idaho migration counts published?

Lucky Peak fall count, published Daily from late August to the end of October, 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 Idaho

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.

Sandhill crane

Peak months as the agency page describes them.

The refuge is known for its sandhill cranes, which use the marsh as a migration stopover as well as breeding ground, but its seasonal writing gives the fall to elk and changing aspen rather than to a crane month. Wildlife is viewed from the county road that encircles the marsh, open sunrise to sunset.

Before you drive out to Idaho

Viewing in Idaho is run by U.S. Fish and Wildlife Service, Grays Lake 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

Idaho sites, refuges and the reporting record

Viewing sites in Idaho, 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 Idaho

U.S. Fish and Wildlife Service, Grays Lake National Wildlife Refuge puts the Idaho peak at Late August through October on Lucky Peak; the refuge names cranes as a migration stopover without fixing a fall month. 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.

Idaho's two autumn sites have almost nothing in common. Grays Lake, in a high basin in the southeast, is the largest hardstem bulrush marsh in North America and is known for its sandhill cranes, which use it as a migration stopover as well as a breeding ground. The refuge's own seasonal writing gives the fall to bugling elk and changing aspen rather than to a crane month, and the marsh is watched from the county road that encircles it. Lucky Peak is the opposite: a 6,000 foot summit ten kilometres from downtown Boise, counted daily from late August to the end of October, where sharp-shinned hawks have topped 2,900 in a season.

Below, one curve per species the agencies document in Idaho: 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.

Sandhill crane

922 research grade sandhill cranes observations have been uploaded to iNaturalist for Idaho across every year the platform holds, and 12 percent of them fall in the four shaded autumn months. The busiest month in the record is April. An autumn month carries about 0.27 times as many uploads as an average month outside autumn. People upload most of everything in June, 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

21 research grade broad-winged hawks observations have been uploaded to iNaturalist for Idaho across every year the platform holds, and 52 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

340 research grade sharp-shinned hawks observations have been uploaded to iNaturalist for Idaho across every year the platform holds, and 48 percent of them fall in the four shaded autumn months. The busiest month in the record is December. An autumn month carries about 1.82 times as many uploads as an average month outside autumn. People upload most of everything in June, 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 Idaho lately

The most recent research grade autumn observation of each species that anyone has uploaded to iNaturalist for Idaho, as a date and the platform’s own coarse locality. Evidence that people do find sandhill crane 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 Idaho

Where can I watch fall migration in Idaho?

Idaho has 2 agency designated viewing sites in this inventory, 1 of them on federal land: Grays Lake National Wildlife Refuge and Lucky Peak hawk count. Every one is a place U.S. Fish and Wildlife Service, Grays Lake 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. Idaho has the largest hardstem bulrush marsh in North America and a sandhill crane population to match, plus a hawk count on a 6,000 foot peak ten kilometres east of Boise.

When is the fall migration peak in Idaho?

U.S. Fish and Wildlife Service, Grays Lake National Wildlife Refuge puts the Idaho peak at Late August through October on Lucky Peak; the refuge names cranes as a migration stopover without fixing a fall month. 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 Idaho sites?

Sandhill cranes at 1 site, broad-winged hawks at 1 site and sharp-shinned hawks at 1 site. 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 Idaho, as a count of uploads to iNaturalist across every year the platform holds.

Will I definitely see sandhill cranes in Idaho?

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 Idaho?

U.S. Fish and Wildlife Service, Grays Lake 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.
