What to look for in nature in Idaho this November

When do bald eagles gather at Lake Coeur d’Alene?

• Wolf Lodge Bay and Higgens Point

  Arrivals from mid-November; the biggest counts usually late November through December · East end of Lake Coeur d’Alene, about 11 miles east of the city off Interstate 90, exit 22, then Highway 97

  The BLM has counted eagles around Wolf Lodge Bay since 1974. Its tally for the 2025–26 season peaked at 294 on November 26, then fell to 157 a week later and to 20 by December 19. The record so far is 409 birds (363 adults and 46 juveniles) on December 20, 2023, so the timing of the peak moves from year to year with the fish. The agency suggests three places to watch: Higgens Point, the Mineral Ridge boat ramp and the Mineral Ridge trailhead. Stay inside the car when birds are close, park well off the road, and never stop on the interstate or on Highway 97 to look.

• Lake Pend Oreille

  Late November onward · Bays and creek mouths around the lake, north of Coeur d’Alene

  The same pattern plays out on Idaho’s largest lake, where kokanee also spawn along gravel shorelines and in the creeks. Fish and Game has described big groups of eagles collecting on both lakes and says spawned-out kokanee stay available to them well into January. When the fish run out, many of the birds drift south toward southern Idaho, Utah and the Klamath Basin.

• How to tell an adult from a young eagle

  All winter · Any shoreline perch

  Only adults, at about five years old, wear the white head and tail. Younger birds are mottled brown and white and are easily mistaken for golden eagles. The BLM logs adults and juveniles separately: young birds were about one in nine during the 2023 record count but one in four on December 10, 2025. Count both on a crowded snag and write down the ratio, just as the surveyors do.

Where can you see trumpeter swans and big flocks of geese in Idaho?

• Trumpeter swans on the Henrys Fork

  Arriving in early November; present through March · Island Park, between Last Chance and Harriman State Park; also the South Fork and Teton River corridors

  The Henrys Fork rises from huge springs, so it runs at a steady temperature and stays ice-free where other rivers lock up. That keeps the underwater plants the swans eat within reach all winter. A Friends of Harriman State Park board member who watches them each fall writes that the first birds appear in early November, flying in from nesting marshes in Canada and Alaska. In its 2013 winter newsletter, Idaho Fish and Game put the number wintering along the stretch past Harriman at roughly 450, and said one midwinter aerial survey had found nearly 60 percent of the Rocky Mountain population, then about 5,500 birds, on rivers of the Upper Snake. Listen for the call: low, bugling and a little like a toy horn.

• Geese and ducks on Lake Lowell

  Geese peak in mid-November; ducks build toward a mid-December peak · Deer Flat National Wildlife Refuge, Lake Lowell, south of Nampa

  The refuge says Canada geese on the lake top out at around 15,000 by the middle of November, while ducks, mostly mallards, keep arriving until mid-December, when there can be as many as 150,000. Bald eagles follow them in to pick off the weak and injured. The lake has been closed to boats since October, so the birds rest undisturbed on open water; a still, cold morning gives the best looks.

• Swans and waterfowl at Camas refuge

  Late fall migration · Camas National Wildlife Refuge near Hamer, north of Idaho Falls

  Camas has a 3.5-mile and a 7-mile auto route through marsh and meadow and is open daily from just before sunrise until just after sunset. Tundra swans pass through in fall alongside the resident trumpeters, and the two take care to tell apart; a tundra is smaller and many show a dab of yellow on the bare skin before the eye. Call the refuge before driving out late in the month, since water and ice change fast.

Where do salmon spawn in Idaho in November?

• Fall Chinook below Hells Canyon Dam

  Spawning from about early October through November · The Snake River from Hells Canyon Dam down toward Lewiston, and the lower Clearwater, Grande Ronde and Salmon rivers

  NOAA Fisheries’ 2025 status summary describes these salmon spawning from early October through November in the mainstem Snake, with eggs that hatch over the winter and young fish that leave for the ocean in late spring. Idaho Power holds the river at a steady flow from Hells Canyon Dam during the spawning season so the nests, called redds, are not left high and dry. The story is a qualified comeback: only 78 wild fall Chinook passed Lower Granite Dam in 1990, and 6,755 naturally produced adults returned in 2024. The redds are deep and hard to see from shore, so the best way to share in it is a jet-boat or float trip, or simply a stop at a Hells Canyon overlook to think about what is happening in the gravel below.

• Kokanee on the lakeshores

  Shoreline spawning peaks around Thanksgiving · Lake Pend Oreille, Lake Coeur d’Alene and Priest Lake

  While the stream runs near Sandpoint and Boise finished weeks ago, the big-lake kokanee spawn late on underwater gravel beaches. You will rarely see the spawning itself; the clue is a line of eagles perched along one stretch of shore.

• Steelhead in a lean year

  Fall season continues into December · Clearwater, Salmon and Snake rivers

  Fish and Game forecast 61,500 steelhead at Bonneville Dam in 2026, the lowest on record, though more than 90 percent are big two-ocean fish. The statewide limit is two a day, and on the Clearwater only one of those may be longer than 28 inches. The bigger B-index fish, the ones Clearwater anglers wait for, are forecast at just 8,100. Check the current rules before any trip; the department has been adjusting them during the season.

When is the deer and bighorn sheep rut in Idaho?

• Bighorn rams clashing

  November and December · Salmon River road downstream of North Fork; Highway 93 between Kriley Gulch and Tower Rock; the Buffalo Jump area off Highway 75 south of Challis; Morgan Creek north of Challis

  Idaho Fish and Game points to these roadside stretches of the upper Salmon for watching the rut. Mature rams square off, rear up on their hind legs and drop forward into each other with a crack you can hear across the river, sometimes for hours. Use binoculars from a pullout; the sheep often feed on slopes right above the highway, and stopping in a traffic lane on a canyon curve is the real danger here.

• Mule deer bucks on the move

  Rut in November and December · Foothills and winter range statewide, from the Boise Front to the Snake River Plain

  Mule deer breed in November and December, and Yellowstone’s biologists note that most of their deer leave the high country for lower winter range as the cold sets in; Idaho’s herds do the same. Rutting bucks with swollen necks follow does in the open, often at midday, and they cross roads without looking. Slow down at dusk on highways through the foothills, and watch for the big, mule-like ears and black-tipped tail that separate them from white-tailed deer.

• White-tailed deer in the north

  Rut peaks in November · Farm edges and river bottoms in the Panhandle, Palouse and Clearwater country

  The north is white-tailed deer country, and the general white-tailed season there runs to December 1 because the rut makes bucks visible. Look for scrapes (pawed patches of bare dirt under a low branch) and rubs, saplings with the bark shredded by antlers, along field edges.

• Bears going to bed

  October to December · Mountains statewide; grizzlies in the Selkirks, Cabinet-Yaak and the Yellowstone border country

  The U.S. Fish and Wildlife Service says grizzlies in the lower 48 states den between October and December, females before males, and stay in for four to six months without eating, drinking or relieving themselves. They usually dig on steep, high slopes where drifting snow piles deep. A bear out in late November is usually a male in no hurry, so keep carrying spray on Panhandle and Island Park trails until there is real snow on the ground.

Which winter birds come to Idaho backyards in November?

• Project FeederWatch

  November 1 through April 30 · Any yard, balcony or schoolyard with a feeder or a berry bush

  The Cornell Lab of Ornithology runs FeederWatch through the winter, and you pick your own count days. Its six-month season begins on the same Sunday the clocks change, so the first count may be in the new afternoon dark. There is a modest annual fee that pays for the project.

• Finches and crossbills

  All winter · Conifers in the mountains and in town

  The Finch Research Network’s 2026–27 forecast concentrates on the East, but it flags a widespread failure of pine cones (limber, whitebark, ponderosa and pinyon) across the interior mountain West. That pushed some red crossbills east this summer and may leave Idaho’s mountain forests quieter than usual. Spruce and fir cones are a different story, so listen for crossbills’ hard “kip” notes wherever those trees have a crop, and report any evening grosbeaks or redpolls to eBird.

• Get ready for the Christmas Bird Count

  December 14, 2026, to January 5, 2027 · Count circles across Idaho

  National Audubon’s count runs from mid-December into early January each year, and the local circles fill their teams in November. Contact your nearest Audubon chapter now if you want to join a field party or count at your feeder inside a circle.

What is in Idaho’s night sky in November?

• The Beaver Moon, a supermoon

  Evenings of Monday, November 23, and Tuesday, November 24 · Rising in the east-northeast around sunset

  The moon is exactly full around sunrise on Tuesday the 24th, so the evenings on either side both look round, Tuesday’s a little closer to the moment. Perigee, the nearest point of the lunar orbit, follows on Wednesday afternoon, near enough to earn the supermoon label, though December’s Cold Moon will come closer still. In the small hours of the 24th it slides past the Pleiades, though its glare all but drowns the little cluster. The New Moon a fortnight earlier is the odd one out on Idaho calendars: just after midnight on the 9th in Boise, but still the evening of the 8th in Coeur d’Alene.

• Leonid meteors

  Before dawn on Wednesday, November 18 (active November 6 to 30) · Rising in the east after midnight; look anywhere high

  On the IMO’s reckoning the Leonids crest at about 4:45 p.m. MST on the 17th, while the sun is still up over Boise, so Idahoans should plan on the next morning instead. A half-lit moon drops behind the western hills near midnight, and from then until the eastern sky pales Leo climbs through true darkness. Fifteen an hour from a black-sky site would be a decent haul; no outburst is due. Leonids hit the air at tremendous speed and now and then leave a smoky trail that glows for a second or two.

• Taurid fireballs

  Southern Taurids peak about November 5, Northern Taurids about November 12 · Taurus, high in the east and south by late evening

  The two Taurid streams are crumbs of Comet Encke and a good night brings perhaps half a dozen meteors an hour. What they lack in number they make up in style: they drift slowly, and a few blaze as fireballs. With the new moon falling between the two peaks, the nights around November 8 and 9 are dark from dusk to dawn.

• Mars meets Jupiter; Venus blazes at dawn

  Mornings of November 15 and 16; Venus all month · East and southeast before sunrise

  The morning sky is the busy one. Jupiter and fainter, orange Mars sit in Leo and pass just over a degree apart on the evening of the 15th Mountain time, so look before dawn on the 15th and the 16th when the pair are up. Venus, low in the east-southeast and climbing higher each morning, is near its brightest from about November 24 to 27, and on the 9th it passes close to Spica, the brightest star in Virgo. Mercury pops up briefly too: try about 45 minutes before sunrise between the 18th and the 25th, very low above the eastern horizon. The only bright planet in the evening is Saturn, in the south after dark.

• Uranus at its best

  Opposition on November 25 · In Taurus, not far from the Pleiades

  Uranus reaches opposition on the 25th, among the stars of Taurus below the Pleiades. Binoculars and a finder chart turn it into a faint blue-green dot; leave it until early December, when the moon is out of the evening sky.

What trees and shrubs are worth a look in Idaho in November?

• Tamaracks dropping their needles

  Early November · Northern and west-central Idaho, from McCall to the Panhandle

  Western larch is a conifer that sheds every needle each autumn, and the last gold usually hangs on into the first days of November before a windstorm brings it down. Afterward the trees look dead until spring. Look at a bare twig with a hand lens: each needle grew from a little peg-like knob, and next year’s cluster of soft needles will sprout from the same spot.

• Big sagebrush, winter’s pantry

  Seeds ripen from October through December · Across southern Idaho’s high desert

  Sagebrush keeps its silvery leaves all winter, and the USDA calls it perhaps the most important shrub on western rangelands. Mule deer, elk, pronghorn and bighorn sheep browse it when grass is buried, and greater sage-grouse live almost entirely on its leaves in winter. Its seeds ripen late in the fall, so November is when the tiny seed heads on the flower stalks shed. Rub a leaf between your fingers; the smell after rain or snow is the smell of the Idaho desert.
