The Danube delta provides a critical refuge for several globally threatened species. It is home to about 330 bird species, including 70% of the world’s white pelican population and 60% of the world’s pygmy cormorants. The delta is home to a remarkable population of glossy ibis, spoonbill, different species of egrets and herons. Most of the European freshwater fish species (around 70 species) exist in the delta.
