How to recognize it
-
Medium-sized wader with a small head, long neck, and fairly solid body.
-
In spring, the male is unmistakable, with a full neck ruff and long head plumes.
-
Females and birds outside breeding plumage are grey-brown above and pale below.
-
In flight, look for a narrow pale wing bar and white patches at the base of the tail.
-
Flight is marked by slow, deep wingbeats.
About the species
The Ruff is a medium-sized wader with a small head, long neck, and fairly solid body. In spring, males change dramatically, developing a full neck ruff and long head plumes, with much brighter breeding plumage.
Ruffs are generally quiet birds. At the lek, males spend most of their time displaying to one another, hopping, flaring their ruffs, and crouching in front of rivals. Outside the breeding season they are much less conspicuous, moving briskly across shallow water and wet ground and sometimes feeding after dark.
During migration, Ruffs can gather in large flocks.
In summer they feed mainly on insects and larvae, while in winter they take more seeds and other plant material. In most parts of their range they are migratory, although some populations stay year-round.
Did you know?

Named after a fashionable collar
The English name Ruff was first recorded in 1634. It comes from the ruff — the large pleated collar fashionable in Europe from the mid-16th to the mid-17th century. The male’s ornamental neck feathers closely resemble this piece of clothing.

The female has her own name
The female Ruff has a separate English name of her own — reeve. Its origin is uncertain. The word may be related to shire-reeve, an old English official title, while the male’s elaborate plumage was compared with formal robes.

Every male has his own breeding look
Each male has his own breeding look: the ruff and head plumes may be black, chestnut, or white, and can be plain, barred, or irregularly patterned. This extreme variation is thought to help males recognize one another at communal leks. That may be especially useful in a species that displays in groups but is usually very quiet.

Where to find
-
Ruffs favour open wet habitats such as shallow water, muddy shorelines, wet meadows, and marshes.
-
They often feed along the water’s edge and beside reeds, moving briskly and picking small invertebrates from the surface and mud.
-
In spring, displaying males can be seen on suitable wet grassland, flaring their ruffs, hopping, and crouching in front of rivals.
-
During migration, Ruffs often gather in groups on flooded ground, temporary pools, and shallow wetlands.
