THE ASSESSMENT OF THE TROPHIC RELATIONSHIPS OF THE MIGRATORY-NESTING BIRDS POPULATIONS BELONGING TO THE FAMILY OF ARDEIDAE IN THE GIZILAGHAJ BAY

Abstract

In 2013-2023, in the Gizilaghaj Bay located on the South-Western coast of the Caspian Sea, the trophic relationships of the migratory and nesting bird populations belonging to the Ardeidae family (Botarus stellaris, Ixobrychus minutus, Nycticorax nycticorax, Ardeola ralloides, Bubulcus ibis, Egretta garzetta, Ardea alba, Ardea cinerea, Ardea purpurea) were evaluated with 100 points. It was evaluated 40-60 (sufficient) in 36 species, the main food objects of which are plants, in 9 species 60-80 (good). It was evaluated 40-60 (sufficient) in 12 species of birds, the main food objects of which are invertebrates, 60-80 (good) in the populations of 114 species and 80-100 (very good) in 10 bird species. It was evaluated 0-20 (very bad) in 14 species, the main food objects of which are vertebrates, 20-40 (bad) in 18 species, 40-60 (sufficient) in 56 species and 60-80 (good) in 10 species.
