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,
Audubon's shearwater homogeneous north-western Indian Ocean range, but not in the ecologically more diverse and by far larger Pacific range of "dichrous". These unresolved problems notwithstanding, this clade – possibly including the preceding one – has been proposed to constitute a separate species, the tropical shearwater or Baillon's shearwater, "Puffinus bailloni". These taxa could not be included in the most recent studies due to lack of material. The case of "gunax" seems fairly straightforward – as certainly as this can possibly be said in the absence of new data, it belongs to the "bailloni" clade either as a distinct subspecies, or, more
