Aphrastura Spinicauda
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 commonest and best-known native bird in temperate forests of Zona Austral and Zona Sur in Chile,Ridgely, Robert S. and Tudor, Guy; ''Field Guide to the Songbirds of South America: The Passerines''; pp. 285-286. often occurring at densities of well over one individual per hectare. Description The thorn-tailed rayadito is approximately in length including the tail, and an average adult weighs around , with males being around 10 percent heavier than females.Moreno, Juan, Merino, Santiago, Lobato, Elisa, Rodríguez-Gironés, Miguel A. and Vásquez Rodrigo A.; "Sexual dimorphism and parental roles in the thorn-tailed rayadito (Furnariidae)" in '' The Condor'' 109(2):312-320 (2007) The most distinctive feature o ...

Diego Ramírez Islands
The Diego Ramírez Islands ( es, Islas Diego Ramírez) are a small group of subantarctic islands located in the southernmost extreme of Chile. History The islands were first sighted on 12 February 1619 by the Spanish Garcia de Nodal expedition, and named after the cosmographer of the expedition, Diego Ramírez de Arellano. They were cited as the southernmost land mass plotted as of that time, and retained the distinction for 156 years, until the discovery of the South Sandwich Islands in 1775. In 1892, the Chilean government rented the islands to Pedro Pablo Benavides for fishing and on condition that a lighthouse, a port, and a school would be built. Later the rent was transferred to Koenigswerther and Pasinowich. The Chilean Navy established a meteorological station above Caleta Condell, a small cove on the northeastern side of Isla Gonzalo (Gonzalo Island), in 1957, and resupplies it several times each year.Dingwall (1995), p. 109. This is the southernmost inhabited outpost ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Des Murs's Wiretail
Des Murs's wiretail (''Sylviorthorhynchus desmursii'') is a small passerine bird of southern South America which belongs to the ovenbird (family), ovenbird family Furnariidae. Molecular phylogenetics places it within the Synallaxinae and indicates that the genus diverged from the ''Leptasthenura'' about 14-15 million years ago. Description It is long, with the very long tail accounting for about two-thirds of this, but weighs as little as .Johnson, Alfredo William (author) and Goodall, J.D. (illustrator); ''The birds of Chile and adjacent regions of Argentina, Bolivia, and Peru'', Volume II; pp. 171-173. The tail consists of just six feathers which are very narrow and filament-like: so few rectrices are elsewhere seen only in the emu-wrens of Australia. The two central feathers are greatly elongated while the two outer feathers are very short. The plain plumage is reddish-brown above, paler on the underparts. There is a pale stripe above the eye. The bird is small and rounded wit ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Nest Box
A nest is a structure built for certain animals to hold eggs or young. Although nests are most closely associated with birds, members of all classes of vertebrates and some invertebrates construct nests. They may be composed of organic material such as twigs, grass, and leaves, or may be a simple depression in the ground, or a hole in a rock, tree, or building. Human-made materials, such as string, plastic, cloth, or paper, may also be used. Nests can be found in all types of habitat. Nest building is driven by a biological urge known as the nesting instinct in birds and mammals. Generally each species has a distinctive style of nest. Nest complexity is roughly correlated with the level of parental care by adults. Nest building is considered a key adaptive advantage among birds, and they exhibit the most variation in their nests ranging from simple holes in the ground to elaborate communal nests hosting hundreds of individuals. Nests of prairie dogs and several social insect ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Amazon Basin
The Amazon basin is the part of South America drained by the Amazon River and its tributaries. The Amazon drainage basin covers an area of about , or about 35.5 percent of the South American continent. It is located in the countries of Bolivia, Brazil, Colombia, Ecuador, Guyana, Peru, Suriname, and Venezuela. Most of the basin is covered by the Amazon rainforest, also known as Amazonia. With a area of dense tropical forest, this is the largest rainforest in the world. Geography The Amazon River begins in the Andes Mountains at the west of the basin with its main tributary the Marañón River and Apurimac River in Peru. The highest point in the watershed of the Amazon is the second biggest peak of Yerupajá at . With a length of about before it drains into the Atlantic Ocean, it is one of the two longest rivers in the world. A team of scientists has claimed that the Amazon is longer than the Nile, but debate about its exact length continues. The Amazon system ...

Austrocedrus
''Austrocedrus'' is a genus of conifer belonging to the cypress family ( Cupressaceae). It has only one species, ''Austrocedrus chilensis'', native to the Valdivian temperate rain forests and the adjacent drier steppe-forests of central-southern Chile and western Argentina from 33°S to 44°S latitude. It is known in its native area as ciprés de la cordillera or cordilleran cypress, and elsewhere by the scientific name as Austrocedrus, or sometimes as Chilean incense-cedar or Chilean cedar.Farjon, A.

It is a member of subfamily Callitroideae, a group of distinct southern hemisphere genera associated with the Antarctic flora. It is closely related to the New Zealand and New Caledonian genus ''Libocedrus'', and some botanists treat it within this genus, as ''Libocedrus chilensis'', though it resem ...

Striped Woodpecker
The striped woodpecker (''Veniliornis lignarius'') is a species of bird in subfamily Picinae of the woodpecker family Picidae. It is found in Argentina, Bolivia, and Chile. Taxonomy and systematics The striped woodpecker was originally described as ''Picus Lignarius''. It was later placed in ''Dyctiopicus'', which was merged into ''Dendrocopos'', which in turn was merged into ''Picoides'' where it and its sister species the checkered woodpecker (''V. mixtus'') were considered outliers. In 2006, Moore et al. published research on mtDNA COI and Cyt ''b'' sequences which suggested that the two belong in genus ''Veniliornis''. That treatment is now (2023) followed by the International Ornithological Committee and BirdLife International's ''Handbook of the Birds of the World''.HBW and BirdLife International (2022) Handbook of the Birds of the World and BirdLife International digital checklist of the birds of the world.
