Wintering of Black-throated Divers (Gavia arctica) on the Eau d'Heure dams (Province of Hainaut) and status in Belgium outside the maritime zone.
Wintering of three Divers, joined by a fourth in January, from 5 December 1982 to 20 March 1983. The status outside the maritime zone is described on the basis of 125 details obtained in Belgium from 1943-44 to 1982-83. The species is at present a winter visitor and exceptionally a winter resident, in very small numbers (1-2 examples at one and the same time, at the most 16 findings during one winter). The increase in the number of records is first and foremost function of the increase in the number of observers.
