Thorn-tailed Rayadito

The thorn-tailed rayadito (Aphrastura spinicauda), is a species of bird in the family Furnariidae. It is found in temperate forests and subtropical dry shrubland south of 30°S. Some sources suggest it may formerly have occurred in the Falkland Islands. It remains the most common and best-known native bird in temperate forests of Zona Austral and Zona Sur in Chile, often occurring at densities of well over one individual per hectare. == Taxonomy == The thorn-tailed rayadito was formally described in 1789 by the German naturalist Johann Friedrich Gmelin in his revised and expanded edition of Carl Linnaeus's Systema Naturae. He placed it with the wagtails in the genus Motacilla and coined the binomial name Motacilla spinicauda. Gmelin based his description on the "thorn-tailed warbler" that had been described and illustrated by the English ornithologist John Latham in his book A General Synopsis of Birds. The naturalist Joseph Banks had provided Latham with a water-colour drawing of the bird by Georg Forster who had accompanied James Cook on his second voyage to the Pacific Ocean. The picture was drawn in December 1774 at the Tierra del Fuego. This picture is held by the Natural History Museum in London. The thorn-tailed rayadito…
