The Srebarna Nature Reserve is a freshwater lake adjacent to the Danube and extending over 600 ha. It is the breeding ground of almost 100 species of birds, many of which are rare or endangered. Some 80 other bird species migrate and seek refuge there every winter. Among the most interesting bird species are the Dalmatian pelican, great egret, night heron, purple heron, glossy ibis and white spoonbill.
The reserve was set up primarily to protect the rich diversity of wildfowl, the bird species represent half of the Bulgarian avifauna. Species found in Srebarna include mute swan, a variety of geese and ducks, red-necked grebe, two of the three European species of marsh tern, and bearded tit. Otter is occasionally found in the reserve. White-fronted goose, red-breasted goose and blue throat have become established as wintering species.
Since 1983 it is a Unesco site.
