The numbers of this species (and of curlew sandpiper) depend on the population of lemmings. In poor lemming years, predatory species such as skuas and snowy owls take Arctic-breeding waders instead.
It is gregarious in winter, sometimes forming large flocks with other Calidris waders, particularly dunlin, on coastal mudflats or the edges of inland pools.
The little stint is one of the species to which the Agreement on the Conservation of African-Eurasian Migratory Waterbirds (AEWA) applies.
