A Steller's sea eagle from the Russian Far East was photographed in interior Alaska in August 2020, then Texas, then Quebec, then Nova Scotia, then Massachusetts, then the coast of Maine. Wing markings confirmed it was the same bird. It has been wandering North America for over five years, roughly 5,000 miles from the nearest breeding population, and it keeps coming back to the same stretch of Maine coastline every winter. Birders nicknamed it Stella. Bald eagles perched next to it looked like pigeons.
A Steller's sea eagle is not a bird most North Americans have any frame of reference for. It weighs up to fifteen pounds. Its wingspan reaches eight feet. Its bill is a massive golden wedge that looks like it was designed to open armored fish. It is about a foot longer and taller than an adult bald eagle and up to five pounds heavier. There are roughly 4,000 left in the wild, all of them in the coastal forests and river systems of Kamchatka, the Sea of Okhotsk, and the Kuril Islands in the Russian Far East. Some winter in Japan and Korea. None of them are supposed to be in North America. A few have shown up on the Aleutian Islands and the western Alaska coast over the years, but always on the Pacific side, always briefly, and always alone.
On August 30, 2020, a photographer captured an adult Steller's sea eagle along the Denali Highway in interior Alaska. That was already unusual. Previous North American sightings had all been coastal. This bird was deep inland. Then in March 2021, photos surfaced from Coleto Creek in southeastern Texas. A Steller's sea eagle, 3,000 miles from Denali, perched over a reservoir in cattle country. The Texas sighting was a single anonymous photo and could not be confirmed as the same individual. Three months later, birders found a Steller's sea eagle on the Restigouche River at the New Brunswick-Quebec border. It stayed in the Quebec region for six weeks. Enough photographs were taken during those weeks to compare individual feather patterns with the Alaska bird. The wing markings matched. It was the same eagle.
In November 2021, it appeared on the Avon River in Nova Scotia for two days and vanished. In mid-December, a photographer named David Ennis found it on the Taunton River in southeastern Massachusetts. Two juvenile bald eagles were perched in a tree along the river. The Steller's sea eagle was on the same branch. The size difference was so extreme that the bald eagles, seven-foot wingspan, ten pounds, one of the largest raptors in North America, looked undersized beside it. MassWildlife confirmed it was the first record of the species in Massachusetts and in eastern North America.
On December 31, 2021, the eagle was spotted at Five Islands in Georgetown, Maine, by a local resident named Linda Tharp. The birding world lost its composure. Hundreds of people drove to Georgetown on New Year's Day. The eagle stayed on the Maine coast for nearly two months, fishing in the Sheepscot River, perching in shoreline spruce trees, and drawing crowds that overwhelmed the parking at every accessible overlook. It was seen almost daily until late February, then it disappeared.
It came back. In the spring of 2022, the eagle flew north through Nova Scotia and spent the summer in Trinity, Newfoundland, feeding on spawning capelin alongside bald eagles on the rocky cliffs. The following winter, it returned to Georgetown, Maine, to the same river where it had spent the previous January. Same trees. Same fishing spots. Two winters in a row, 5,000 miles from the Sea of Okhotsk, and the bird came back to the same stretch of Maine coastline as if it had filed a forwarding address.
It returned to Trinity, Newfoundland, again in the summer of 2023. In the winter of 2023-2024, it was spotted in the Codroy Valley on Newfoundland's west coast. In December 2024, it was photographed at Terra Nova National Park.
Nobody knows why it is here. Steller's sea eagles do not migrate to North America. The species has no historical range on this continent. The working theory is that the bird, likely a young adult when it first appeared, drifted east from Kamchatka or the Aleutians during a weather event or a failed migration and simply never corrected. It found fish. It found coastline. It found bald eagles it could dominate at every carcass and every river. Nothing in North America is large enough to threaten it. Nothing competes with it for food. It is the biggest raptor on the continent by a wide margin and it has no reason to leave.
The bird is still being tracked through eBird sightings and feather-matched photographs. It appears healthy. It has survived at least five North American winters, fed itself consistently, and established a pattern of seasonal movement between Newfoundland in summer and the Maine or Nova Scotia coast in winter. It built a migration route on a continent where its species has never migrated, using landmarks it taught itself, returning to specific rivers and specific trees year after year, alone, the only one of its kind within 5,000 miles.
