Calvià to the islands. Local native plant species include holm oak ("Quercus ilex") and various pine species. There are over 1,000 animal species; notable among them are the seabirds Cory's shearwater ("Calonectris diomedea"), various cormorants ("Phalacrocorax"), the common swift ("Apus apus"), and the Manx shearwater ("Puffinus puffinus") as well as numerous reptiles, such as the endemic Lilford's wall lizard ("Podarcis lilfordi") found on several of the islets of the archipelago. The islets are also home to one of Spain's few colonies of Hermann's tortoise ("Testudo hermanni"; other colonies are in Murcia and Almería). Although the vegetation on the cliffs is sparse,
Wedge-tailed shearwater (in common with the other shearwaters) as an adaptation for swimming. This species is related to the pan-Pacific Buller's shearwater, which differs much in colour pattern, but also has a wedge tail and a thin black bill. They make up the "Thyellodroma" group, a superspecies of the large shearwaters that were for a long time included in the genus "Puffinus". Wedge-tailed shearwaters feed pelagically on fish, squid and crustaceans. Their diet is 66% fish, of which the most commonly taken is goatfish. It was thought that the species mostly took food from surface feeding, observations of feeding wedge-tails suggested that
