Résumé :	This paper presents recent data for the White-headed Duck Oxyura leucocephala in the Tengiz-Korgalzhyn Region, Central Kazakhstan. Most data were collected during surveys in the summer and autumn (July-October) 1999-2002. The region proved to hold significant numbers of the Central Asian population of White-headed Duck in late summer/autumn. Numbers peak in September. It is estimated that 4,000-4,500 birds are present at this time of the year. The size of the local breeding population is unknown. It is assumed that both the local population and birds from northern Kazakhstan and southern Siberia contribute to the autumn gatherings. Most autumn aggregations were found on lakes outside the Korgalzhynskij Nature Reserve (Zapovednik), while the reserve itself holds the main breeding sites. As it is essential to maintain numbers to ensure the survival of the Central Asian population, threats and conservation actions are discussed. The legal protection status seems favourable for the protection of the population. The main threats stem from water supply and management. Further problems include disturbance by hunters and fishermen.
