These stocky shorebirds stand out among their fellow migrants in spring, resplendent with rich rufous breasts shading into white on the lower belly. Red knots have short, black bills tapering to a fairly fine tip; short legs give them a low-slung appearance. They are highly gregarious and tend to form tight foraging and roosting flocks.
Found primarily on the coast, they are regular transients in spring and fall. Knots forage on open estuarine tide flats, less commonly on margins of sand ocean beaches. Inland, they are found on margins of sewage ponds and at large brackish lakes such as Malheur and Summer Lakes.
