Abstract

The author presents results of the Hungarian Waterfowl Monitoring (HWM) referring to the season 2005/2006. This treatment does not cover geese, the latter being the subject of another publication. Basic data obtained at the 49 sites (Table 1. and Map 1.) are presented for each observed site in Table 3-25. The tables are followed by statements concerning each of the species in regard of population size (Hungary total), population dynamics (Hungary total), territorial dispersion of each species, dynamics characteristic for the certain sites of observations, and on the basis of maximum numbers of various species at the respective sites: designation of areas bearing international importance according to Ramsar Convention Criterion 6. (see Table 2.)(Wetlands International, 2006). The facts mentioned afore are presented for each of the species by means of figures, tables and maps (Table 26-63., Map 2-39. Figure 1-56.) In the framework of the Hungarian Waterfowl Monitoring performed in 2005/2006 we did not obtain data on the following species: Great Northern Diver (Gavia immer), Bewick’s Swan (Cygnus columbianus), Pink-footed Goose (Anser brachyrhynchus), Canada Goose (Branta canadensis), Marbled Teal (Marmaronetta angustirostris), King Eider (Somateria spectabilis) and White-headed Duck (Oxyura leucocephala). Lack of data on the 7 species listed above is due to the fact that on the days of synchronous counts of the HWM no individuals of these species were to be seen. As the results of the Hungarian Goose Monitoring are assessed separately, the present paper comprises the results of observations on 37 species. The order of rank of observed waterfowl species as well as the dynamics of the order (Table 65-67.) shows clearly whether species declared huntable are really those with highest numbers. In the report international significance of each site is defined according to 1% Ramsar Convention Criterion 6. For each site those species are listed on the basis of which the aforementioned statement has been made.
