Dalmatian Pelican

The Dalmatian pelican, also known as the curly-headed pelican, is the largest member of the pelican family and among the heaviest flying birds in the world. With a wingspan typically ranging between 2.7 and 3.2 metres, it ranks among the largest soaring birds. These pelicans are known for their graceful flight and often travel in synchronised flocks. With a range spanning across much of Central Eurasia, from the eastern Mediterranean in the west to the Taiwan Strait in the east, and from the Persian Gulf in the south to Siberia in the north, it is a short-to-medium-distance migrant between breeding and overwintering areas.
