Hares, deer, mouflons
The European hare (Lepus europaeus sp.) lived on the island and between 1902 and 1908 the Aksis deer (Aksis aksis), the fallow deer (Dama dama) and the mouflon (Ovis musimon) were imported, so their descendants still adorn the forests, parks and glades of Brijuni and are part of its identity.
Autochthonous world of birds
The autochthonous birds are quite well represented. Some of the smaller islands are excellent habitats where gulls and sea swallows nest, as well as some rare genuses of cormorants. Brijuni are also important seasonal habitats of northern bird species and the most interesting is the locality of Saline. It is a very damp area with three marshy lakes of 8 acres of fenced area with the aim of forming an ornithological reservation. The biggest lake is overgrown with reed and is a good nestling ground for pratincoles, quails, coots, grebes and wild ducks.
In the swamp ooze and shallow water the birds find insects, mosquito larvae and gambusias, small fish that have had an important role in the recovery of the island from malaria at the beginning of the century. I In this fenced area the underbrush and the low plant cover can grow undisturbed because there is no influence of game, therefore this habitat is ideal for many species of warblers, nightingales, blackbirds, chiffchaffs and other songbirds.
In the crowns of pines we can find nests of sparrow hawks, goshawks and common buzzards. Of other predatory birds there are the marsh harriers and moor harriers.
By the end of the summer many different bird species come to Soline on their way to the south.
Already in August we can see widgeons, whistling ducks, diving ducks and swallow ducks.
Of herons we can see the little egret, the common heron, the yellow-crowned night heron and the rook.
The arrival of the great white egrets, the black storks and the bitterns indicates that this area is also important for such rare and endangered species, which here find their peace and enough quantities of food.
