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,
Procellariidae with "Pseudobulweria" being phylogenetically closer to the "Puffinus" shearwaters than the "Pterodroma" gadfly petrels, and "Aphrodroma" (the Kerguelen petrel) possibly being closely related to the shearwaters or the fulmars. The prions, according to Nunn and Stanley, were among the larger shearwater group. The "Calonectris" shearwaters were placed close to the two "Puffinus" clades (closer to the Puffinus, or small, clade) and both were distant to the "Procellaria" shearwaters. The relationships between the genera and within the genera are still the subject of debate, with researchers lumping and splitting the species and genera within the family and arguing about the position
