Xəzərin cənub-qərb sahilində suyun səviyyəsinin enməsinin ördəklər (Anatidae) fəsiləsindən Azərbaycanın "Qırmızı kitab"ına daxil edilən növlərin əsas qışlama yerlərinə təsiri

The effect of the lowering of the water level in the Caspian Sea in 2020-2024 on the main wintering places of the Anatidae family included in the Red Book (2023) on the south-western coast of the Caspian Sea was studied. 10 migratory-wintering species from the Anatidae family on the south-western coast of the Caspian Sea have been included in the Red Book of Azerbaijan (Branta ruficollis, Anser erythropus, Cygnus olor, Cygnus bewickii, Marmaronetta angustirostris, Aythya ferina, Aythya nyroca, Clangula hyemalis, Melanitta fusca, Oxyura leucocephala). A sedentary population of one of these species, Aythya, also inhabits the area. These wintering species migrate from Northern and Central Europe, Russia and Northern Kazakhstan. The lowering of the water level on the southwestern coast of the Caspian Sea has led to a decrease in the area of the main wintering places of these birds and has led to a change in their trophic and biotope relationships.
