Canary Islands ocean in the middle of the islands of La Gomera, Tenerife and La Palma; where the laurisilva forests grow. The seven major islands, one minor island, and several small islets were originally volcanic islands, formed by the Canary hotspot. The Canary Islands is the only place in Spain where volcanic eruptions have been recorded during the Modern Era, with some volcanoes still active (El Hierro, 2011). Volcanic islands such as those in the Canary chain often have steep ocean cliffs caused by catastrophic debris avalanches and landslides. The Teide volcano on Tenerife is the highest mountain in Spain, and the
European storm petrel resembles the chatter-call. Chicks give a whistling "pee-pee-pee" call when being fed, and a faster version of this vocalisation is used by adults and young to signal distress. Storm petrels breed only in the Western Palaearctic on islands off the Atlantic and Mediterranean coasts of Europe. The largest colonies are in the Faroe Islands (150,000-400,000 pairs), United Kingdom (20,000-150,000), Ireland (50,000-100,000) and Iceland (50,000-100,000), with smaller breeding areas off Norway, Malta, Spain, the Canary Islands, Italy, France and Greece. The strongholds of the "melitensis" subspecies are the island of Filfla (Malta), Sicily and the Balearic Islands, with smaller sites elsewhere
