Abstract

Wetlands are a critical part of our natural environment. They protect our shores from wave action, reduce the impacts of floods, absorb pollutants and improve water quality. They provide habitat for birds and plants and many contain a wide diversity of life, supporting plants and birds that are found nowhere else. Identifying of habitat ecology and needs of birds, especially those in vulnerable situation is of great importance for protection and management programs as well as continuous monitoring. For conducting this study, the Shirinsoo lagoon was investigated. Random sampling was done for identifying, counting and recording of composition of aquatic migratory birds’ populations in study site with monthly frequency. Variation in number of species was the core part of sampling process. According to the results, total birds of the shirinsoo lagoon are 2725 bird individuals from 54 bird species. Accordingly, the largest population of migratory species was observed in the November and the lowest one was recorded in the February. This study indicated that largest population is Chlidonias leucoptera with a number of 295 and the lowest one is Grus grus and Gallinula chloropus with observed population of only one individual during the whole year. According to observation of birds diversity this lagoon have a major role in the migration course and reproducing of waders and aquatic birds.
