Abstract
The Great Cormorant Phalacrocorax carbo is a wide spread breeding species in Mongolia with a progressive population trend. Observations of the Mongolian-German Biological Expeditions were analyzed and summarized with data from literature. About 1,500 young birds were ringed in 2016 and 2017. One important recovery was coming from the wintering area Mai Po Marshes Nature Reserve of Hong Kong. It is unclear if all Mongolian Cormorants are flying at the same route to their wintering region in South China. The main feeding fishes in Mongolia belong to endemic species of the genus Oreoleuciscus (Cyprinidae). Measurements of 113 eggs from Tolbo- and 155 eggs from Bööncsagaan-nuur were compared with statements of European collections. There were no great differences, but a higher variation in the measurements of Mongolian Cormorant eggs.
