Ornithological reserve Swan's Islands has
international significance, and it is part of the Crimean nature reserve,
although it is located not on the very north-west coast, but is removed from
the coast by 3.5 kilometers in the Karkinitsky Bay. Swan's Isles consist of six
separate islands stretching along the bay for 8 kilometers. The largest of the
group's islands is the fourth, its length is about 3.5 kilometers, and the
width is about 350 meters.
Around the reserve Swan's Islands, both on the water
and on the shore, the boundaries of the guard zone are defined.
The islands were formed as a result of sediments of
shells and sand, so the species, and most importantly, the number of islands
can change with time. Above the surface of the water, almost all the islands
rise equally - 1-2 meters.
The island land and the surrounding water have rich
animal and vegetable food, and the shallow and warm waters of the bay attract a
variety of birds, mostly waterfowl, to this part of the Black Sea. The security
zone of Swan's Islands is approximately 52 hectares. Therefore, 320 species of
birds feathery feel here, and about 25 species of ships are coming to the
nesting grounds.
Swan's islands can boast of being the largest
wintering and nesting site for swamp and waterfowl in Crimea. In addition, this
ornithological reserve is on the way, which every year makes migratory birds,
trying to go to wintering from European countries to Africa and Asia.
For nesting Swan's islands have chosen silver gulls,
gull-laughing gulls, black-headed gulls, white and gray herons, pelicans,
waders, flamingos and other birds. But most of all Lebyazhy Islands are proud
of swans-doves. The Crimea became a real pilgrimage site for these birds, and
over 6,000 gather here during the summer season. On the islands in the
Karkinitsky Bay, swan-doves don’t nest, but only survive moulting, during which
birds are very vulnerable. And in the last days of autumn, these Crimean
islands are occupied by swan-swimmers, who make here a short stop before a long
flight to wintering places.
In addition to birds, in this ornithological reserve,
dolphins, such as whitefish and bottlenose dolphins, as well as porpoises, a
white chorus and a large jerboa, found themselves in the Black Sea. They
inhabit the Swan Islands and reptiles - yellow-belly skid, steppe viper, and,
of course, many fish, in particular rare Black Sea salmon and others.
