Editing Juan Fernández Islands (section)

===Fauna===
The Juan Fernández Islands have a very limited fauna, with no native land [[mammal]]s, [[reptile]]s, or [[amphibia]]ns. Seventeen land and sea-bird species breed on the islands. The island has three endemic bird species, and three endemic subspecies. Introduced fauna by humans include [[rat]]s and [[goat]]s. [[Robinson Crusoe Island]] is home to an endemic and endangered [[hummingbird]], the [[Juan Fernández firecrown]] (''Sephanoides fernandensis''). This large [[hummingbird]], about {{convert|11|cm|0|abbr=on}} long, is thought to number only about 500 individuals. The other endemic bird species are the [[Juan Fernández tit-tyrant]] (''[[Anairetes]] fernandezianus'') of Robinson Crusoe Island, and the [[Masafuera rayadito]] (''Aphrastura masafuerae'') of Alejandro Selkirk Island.<ref>{{Cite web|url=http://tropicalconservationscience.mongabay.com/content/v7/TCS-2014-Vol7(4)_677-689_Gonzalez.pdf|title=Gonzalez J.

The endemic Juan-Fernandez spiny lobster (without claws) lives in the marine waters (''[[Jasus frontalis]]''). The [[Juan Fernández fur seal]] (''Arctophoca philippii'') also lives on the islands. This species was nearly exterminated in the sixteenth to nineteenth century, but it was rediscovered in 1965. A census in 1970 found about 750 [[fur seal]]s living there. Only two were sighted on the [[Desventuradas Islands]], located some {{convert|780|km|mi|0|abbr=on}} to the north. The actual population of the Desventuradas may be higher, because the species tends to hide in sea caves. There seems to be a yearly population increase of 16–17 percent.
