At the time of human arrival, the only terrestrial mammals native to the Balearic Islands were the dwarf goat-antelope Myotragus, the giant dormouse Hypnomys, and the shrew Nesiotites hidalgo which were found on Mallorca and Menorca, which became extinct shortly after human arrival. The only other terrestrial vertebrates native to the islands are Lilford’s wall lizard, which today is confined to offshore islets surrounding Mallorca and Menorca, the Ibiza wall lizard native to the Pityusics, and the Majorcan midwife toad, today only found in the mountains of Mallorca. An extinct dwarf subspecies of Lataste’s viper, Vipera latastei ebusitana, was also native to the Pityusics until it became extinct after human settlement. The Balearic warbler is an endemic bird species found on the islands excluding Menorca. Seabirds nesting on the islands include the Balearic shearwater, European storm petrel, Scopoli’s shearwater, European shag, Audouin’s gull and the yellow-legged gull.
