Similar Species Comparison
When on the ground, it can be confused with the red-necked stint (Calidris ruficollis), but the long-toed stint is more finely built and slightly smaller.
Breeding Season and Range
The long-toed stint breeds in Siberia during the Northern Hemisphere summer. Little is known about its breeding habits, but its breeding range includes the Chukchi Peninsula, the Koryak Plateau, the Commander Islands, the Kuril Islands, land bordering the Sea of Okhotsk, northern Verkhoyansky District, and the areas around the Ob River and the Irtysh River.
Post-Breeding Migration Routes
After breeding, it migrates southward, passing through China, Indochina, Malaysia, and the Philippines, and westward to Burma, Bangladesh, Nepal, Sri Lanka, and the Maldive Islands.
Winter and Vagrant Range
It is a Northern Hemisphere winter visitor to New Guinea and Australia, and a vagrant to Great Britain, Sweden, South Africa, Melanesia, Hawaii, the northwestern United States, and the vicinity of the Bering Sea.
Overwintering Habitat
In its overwintering range, it uses a variety of wetland habitats, including shallow freshwater or brackish areas, lakes, swamps, floodplains, marshes, lagoons, muddy shores, and sewage ponds.
