Oxyura jamaicensis
Habitat:
  • Ruddy ducks inhabit lowland wetlands with lush emergent vegetation and suitable patches of open water. They favour pools with fairly shallow bottoms and those which are rich in floating and submerged aquatic plants. The birds actively avoid flowing freshwaters and estuaries and saline lagoons.

Description:
  • Ruddy ducks (Oxyura jamaicensis) are small, stout freshwater diving ducks with broad, short wings and narrow, stiff tails. It is a relatively small duck (35-43cm long, with a wingspan of 53-62cm) and is rarely seen away from water.
  • The male is unmistakable, with its bright chestnut red breeding plumage, cobalt blue bill and narrow stiff cocked tail. The female is a duller brown colour.

  • The UK holds 95% of the feral Ruddy Ducks in Europe

Impacts:
  • They threaten the survival of the globally endangered White-headed Duck Oxyura leucocephala with which it hybridises

How did it get here?
  • Natural dispersal from Britain to Northern Ireland.

Is it found in Northern Ireland?
  • It is present in Northern Ireland.
  • Northern Ireland population is estimated at twenty five to thirty pairs with a wintering population of around seventy to seventy five birds. 
  • Numbers may be underestimated due to the secretive nature of the species and it is possible that this species is much rarer in the region.
  • More distribution information can be found at NBN Atlas NI.
