How to tell it apart

What does a Ruff look like?

The Ruff is a medium-sized bird, about 22–32 cm long and weighing 70–250 g, identified by its pot-bellied shape, small head, long neck; prominent white ovals on tail sides; juvenile: Warm buff breast and flanks; and variable leg colour (yellow, orange, green).

The ruff is a medium-sized wading bird that breeds in marshes and wet meadows across northern Eurasia. This highly gregarious sandpiper is migratory and sometimes forms huge flocks in its winter grounds, which include southern and western Europe, Africa, southern Asia and Australia.

  1. 01

    Pot-bellied shape, small head, long neck

    A heavy, compact body combined with a disproportionately small head and noticeably long neck creates a unique, often hunched profile.

  2. 02

    Prominent white ovals on tail sides

    In flight, two distinct white oval patches are visible on either side of the dark central rump and tail.

  3. 03

    Juvenile: Warm buff breast and flanks

    Young birds display a strong buff wash on the breast and flanks, contrasting with neatly scaled grey-brown upperparts.

  4. 04

    Variable leg colour (yellow, orange, green)

    Leg colour is highly variable, ranging from bright yellowish-orange to dull pinkish, and sometimes dark greenish, especially in juveniles.

Field tips

behaviour

  • Often stands in an exaggerated, upright posture when wary, making the head look disproportionately small for the body.

flight

  • Flight is characterized by deep, slow, and deliberate wingbeats; watch for diagnostic white oval patches on either side of a dark central tail stripe.

plumage

  • The upperparts feature a prominent 'scaly' pattern caused by dark feather centers with broad, pale buff or greyish-brown fringes.

size_and_shape

  • Look for a distinctively pot-bellied and heavy-bodied silhouette paired with a disproportionately small head, medium-length bill, and a longish neck.
  • This species exhibits striking sexual size dimorphism; males are noticeably larger and bulkier than the females, which is often obvious when observing mixed groups.
