Having the patience to proceed in strict silence along the many paths of Mount Etna, each visitor could have the opportunity to observe some prominent elements of the variegated wildlife of the volcano. Among the easier visible species, the birds: if you are lucky, you could be able to observe the golden eagle (Aquila chrysaetos) twirling up in the sky, while the easier birds to see are the Sicilian partridge (Alectoris greca whitakeri), the crossbill (Loxia curvirostra) and the sparrow hawk (Accipiter nisus). Among the mammals, the red fox (Vulpes vulpes), the weasel (Mustela nivalis) and the fascinating wild cat (Felis sylvestris). Amphibians and reptiles are also very common such as the Sicilian green toad (Bufo siculus), the Mediterranean painted frog (Discoglossus pictus), the Sicilian pond turtle (Emys trinacris) and the dangerous southern viper (Vipera hugyi). Almost impossible to mention all the invertebrate species, represented by colourful butterflies, including the endemic Etna aurora (Anthosharis damone), hundreds of species of Orthoptera, like the gigantic Saga pedo, and many other insects.
