Pelicans flock by the thousands in Oklahoma, raptors soar across mountain ridges in Montana, whales make their final splash off Massachusetts and the forests across several States echo with the primal bugle of rutting elk and moose.
The first week of October isn’t just another page on the calendar. This week offers a rare convergence of wildlife spectacles that you may have never heard of before.
American White Pelicans Flock To Oklahoma
Each fall, as many as 50,000 American white pelicans arrive at Salt Plains National Wildlife Refuge in north-central Oklahoma.
The salt flats and reservoirs serve as the perfect refueling stop on their way from the northern prairies to the Gulf Coast and Mexico.
Every year, the town of Grove hosts a Pelican Festival in Wolf Creek Park by Grand Lake to celebrate this spectacle. This year marks its 42nd anniversary, running from October 2 to 5, 2025.
If you are already taking a fall road trip down to Oklahoma, it may be worth timing it around the first week of October to spot pelicans in the sky.
Thousands Of Raptors Circling High Above In Montana
The Bridger Raptor Festival on October 4–5 celebrates the largest known Golden Eagle migration in the United States, with an average annual count of 1,200 to 1,500 birds.
However, Golden Eagles are not the only birds flying on the Bridger Flyway this time of the year. Add the same number of hawks, falcons, and other eagle species, such as Bald Eagles or Rough-legged Hawk, and you will get 2,000-3,500 birds gliding effortlessly along the ridgeline.
The last 10 days of September and the first 10 days of October are peak birdwatching times in Bozeman, Montana. It is indeed a short window to witness this unique wildlife moment.
Last-Chance To See Humpback Whales Off Massachusetts
Humpback whales feed all summer into fall off the coast of Massachusetts in Stellwagen Bank National Marine Sanctuary, one of their main feeding grounds in the Atlantic.
However, in October, most of them begin heading south. By mid-October, they are almost all gone.
If you are in Cape Cod or by Gulf of Maine, this week is one of the last chances to go on a whale watching tour before the whales disappear into the Caribbean for winter breeding.
Swimming with whales is prohibited in the U.S., but boat-based tours still offer unforgettable encounters as the giants breach and splash.
For anyone who hasn’t checked whales off their list this year, this is the deadline nature set for you, at least in Maine. Before reaching the Caribbean, humpbacks trace a path along several U.S. coasts.
Peak Elk Rut Echoes In The Valleys
Few natural events, especially during fall, are as theatrical as the elk rut. The piercing bugle of males, the clash of antlers and the raw battles for dominance define the first week of October across numerous U.S. National Parks.
Moraine Park and Horseshoe Park are two famous stages of elk mating season in Rocky Mountain National Park, Colorado. Each year, the spectacle draws thousands of onlookers. Noting here that all visitors need time-entry tickets until October 13, 2025.
Cataloochee Valley and the fields near Oconaluftee are the places to be if you want to witness the elk rut in Great Smoky Mountains National Park.
In Grand Teton National Park, Wyoming, early October is the peak in Willow Flats and along the Snake River bottoms.
The rut also remains intense in early October in Yellowstone National Park. Mammoth Hot Springs, Hayden Valley, and Lamar Valley are alive with activity.
Giants of the North Rut In Maine
While Alaska’s moose rut winds down by early October, visitors can still catch this wildlife moment in Maine.
The Pine Tree State is home to 40,000-60,000 moose, the largest population in the Lower 48.
The North Woods are alive with bulls weighing over half a ton. Along U.S. Route 201, around Moosehead Lake, and in Baxter State Park, the first two weeks of October are prime for seeing bulls locking antlers or calling for mates.
It’s one of America’s most raw and unfiltered wildlife displays. But once mid-October passes, the spectacle fades for another year.
