Fauna of Alonnisos
Fauna of Alonnisos
The fauna of Alonissos - mammals, birds and reptiles - belong to a silent and invisible world, which escapes our perception and senses. Only large birds, when they pass over, can be noticed by the careful observer.
It took years of in-depth observations, activated on the occasion of the establishment and management of the Alonissos and Northern Sporades Marine Park, to draw up the basic lists of animal species - this chapter is based on these works.
The general picture of the terrestrial fauna is what one would expect for the geographical and ecological profile of the island, while the marine fauna attests with its richness and rarity the correctness of the protection measures for the area.
Due to the small size, the geographical isolation and the centuries-old human presence on Alonissos, the mammals that live on the island are limited to small carnivores (martens, weasels), insectivores (hedgehogs, bats, shrews) and rodents. As in many other islands, Wild rabbit (Oryctolagus cuniculus) thrives here.
Wild goats (Capra aegagrus), i.e. domestic goat, which has returned to a semi-wild state, roam freely on Peristera Island (and perhaps on other islands).
The area is also home to a remarkable variety and populations of dolphins, with the Common dolphin (Delphinus delphis), the Bottlenose dolphin (Tursiops truncatus) and the Striped dolphin (Stenella coeruleoalba) being the most abundant.
The avifauna of Alonissos is quite rich and interesting. The species that have been observed here show three different patterns of presence: first, the resident or migratory birds that stay on the island, second the birds of the coastal wetlands and the sea, which also stay for some time on or near the land, and last, the birds that pass through migration and are occasionally observed.
The raptors are represented with a few resident species, such as the Kestrel (Falco tinnunculus), the Peregrine falcon (Falco peregrinus) and the Common buzard (Buteo buteo). In late Spring arrive the birds of pray that stay on the island, like Short-toed eagle (Circaetus gallicus) and Eleonora's falcon (Falco eleonorae), which nests in the Aegean islets. Finally, there are reports of the Red-footed falcon (Falco vespertinus), which is observed during its migration to Northern Europe, but also of the Lesser kestrel (Falco naumanni), which comes to Central Greece in the summer. There have also been observations of the Goshawk (Accipiter gentilis) and the Sparrowhawk (Accipiter nisus), which probably spend some time on the island, hunting in the clearings of the forest and the scrubland. Nocturnal birds of pray are represented by the Little owl (Athene noctua) and the Scops owl (Otus scops).
Among the seabirds that one could see in these areas most noteworthy are the Scopoli's shearwate (Calonectris diomedea), the Storm petrel (Hydrobates pelagicus), the Audouin's gull (Larus audouinii), the Little gull (Larus minutus) and the Yelkouan shearwater (Puffinus yelkouan).
Finally, some rare visitors have been reported, such as the Osprey (Pandion haliaetus) and the Great white pelican (Pelecanus onocrotalus).
In the vast shrubland, the observer will guess the presence of the tiny Warblers, hiding themselves behind the branches, with the most notable being the Blackcap (Sylvia atricapilla), the Rüppell's warbler (Sylvia rueppelli), the Garden warbler (Sylvia borin), the Western subalpine warbler (Sylvia cantillans), the Common chiffchaff (Phylloscopus collybita) and the Willow warbler (Phylloscopus trochilus).
In Chora we will see the Common swifts (Apus apus) and the Alpine swift (Tachymarptis melba), together with the swallows (Common house martins, Red-rumped swallow and common Barn Swallows), speeding through the air.
Reptiles find in Alonissos ideal climatic conditions, but also their favorite variety of shady and bright environments, where they can choose the best conditions and temperatures, depending on the time of day.
The geographical isolation of the island, however, has a limiting effect on the number of species and thus the reptile fauna of the area consists of 14 species - six lezards, two turtles and six snakes.
Lizards are represented in Alonissos by the Erhard's wall lizard (Podarcis erhardii), the European copper skink (Ablepharus kitaibelii), the Balkan green lizard (Lacerta trilineata), the Kotschy's gecko (Mediodactylus kotschyi, in the Sporades the fuchsi subspecies has been identified) and the Mediterranean house gecko (Hemidactylus turcicus).
