Number Density, Dynamics, Concentration Places and Status of Species from the Genera Diving Ducks (Aythya Boil, 1822) and Mergansers (Merqus Linn., 1758) in the South Part of the Azerbaijan Sector of Caspian Sea

Abstract

The information about the number, density, the largest concentration places, and the status of species of genera Aythya and Merqus in the South part of the Azerbaijan sector of the Caspian Sea presented in the paper. It was revealed that 4 species of Aythya and 3 species of Merqus live in Azerbaijan .Four species of the genus diving ducks (common pochard - Aythya ferina Linn., 1758, white-eyed pochard - Aytha nyroca Ciuld, 1770, tufted duck - Aythya fuligula Linn., 1758, greater scaup - Aythya marila Linn., 1761) is spread in the southern coast of the Azerbaijan sector of the Caspian Sea. One of these species (the white-eyed pochard) is found annually, and the other is found both in winter and during migration [1]. The white-eyed pochard is included both in the Red Book of Azerbaijan and in the Red List of the International Union for Conservation of Nature [2, 3]. The common pochard is included only in the Red Book of the International Union for Conservation of Nature [3].
