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,
Hutton's shearwater a white underbelly and brown collar, dark borders to the underwing, dark grey bill, and pinkish dark-webbed feet; it can be distinguished from fluttering shearwater by its dark grey "armpits". At a breeding colony it has a loud cackling call. Hutton's shearwater feeds in the open ocean largely on small fish and krill, diving up to 20 m. "Puffinus huttoni" have long bills, which are adapted to catch prey more or less underwater by plunging from a few meters above the surface or by paddling slowly forwards searching with their head submerged, then diving using partly opened wings for propulsion.
