Agelasticus Xanthophthalmus
The pale-eyed blackbird (''Agelasticus xanthophthalmus'') is a species of bird in the family Icteridae. It is found in Ecuador and Peru where its natural habitat is swamps. An inconspicuous bird of very local occurrence, it was first described in 1969 by American ornithologist Lester L. Short. Description The adult pale-eyed blackbird is entirely black in both sexes. It has white or pale buff coloured irises to its eyes which are very distinctive and distinguish it from other black birds found in the area such as the velvet-fronted grackle and the shiny cowbird which have dark eyes. Juveniles and immature birds are brownish-black with underparts streaked with yellow or buff. The call is a loud metallic "tew-tew-tew-tew" similar to that of a black-capped donacobius. It is usually sung from the top of a shrub. Distribution and habitat The pale-eyed blackbird is found in a restricted area of eastern Peru and Ecuador. Its habitat is marshy areas round lagoons and oxbow lakes and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Limoncocha National Biological Reserve
Limoncocha National Biological Reserve is a nature reserve is located 229 miles from Quito, Ecuador. The reserve includes over 11,000 acres (44 km2) of land in the Shushufindi Canton, Sucumbíos Province. Fauna There is a large concentration of Fauna in and around the reserve. The over 347 species of bird that live in the reserve make Birdwatching very popular attraction. Limoncocha also holds a large number of tortoises and a diverse population of fish. Flora The park is a largely water environment so a large portion of the Flora in the Nature reserve is either aquatic or semi-aquatic in nature. As with much of Ecuador towering trees provide homes for hundreds of types of animals. The microscopic algae in the water gives it a lemon green color. Attractions Much of the reserve is a lagoon style landscape that was formed by the ancient course of the Napo River.

Birds Described In 1969
Birds are a group of warm-blooded vertebrates constituting the class Aves (), characterised by feathers, toothless beaked jaws, the laying of hard-shelled eggs, a high metabolic rate, a four-chambered heart, and a strong yet lightweight skeleton. Birds live worldwide and range in size from the bee hummingbird to the common ostrich. There are over 11,000 living species and they are split into 44 orders. More than half are passerine or "perching" birds. Birds have wings whose development varies according to species; the only known groups without wings are the extinct moa and elephant birds. Wings, which are modified forelimbs, gave birds the ability to fly, although further evolution has led to the loss of flight in some birds, including ratites, penguins, and diverse endemic island species. The digestive and respiratory systems of birds are also uniquely adapted for flight. Some bird species of aquatic environments, particularly seabirds and some waterbirds, have further ...

Agelasticus
''Agelasticus'' is a genus of birds in the New World blackbird and oriole family Icteridae. They have slender forms and narrow bills. Male plumage is mostly or entirely black while that of females is generally brown and streaky. Females are responsible for building the nest, unlike some of their close relatives.

Least-concern Species
A least-concern species is a species that has been evaluated and categorized by the International Union for Conservation of Nature (IUCN) as not being a focus of wildlife conservation because the specific species is still plentiful in the wild. They do not qualify as threatened, near threatened, or (before 2001) conservation dependent. Species cannot be assigned the "Least Concern" category unless they have had their population status evaluated. That is, adequate information is needed to make a direct, or indirect, assessment of its risk of extinction based on its distribution or population status. Evaluation Since 2001 the category has had the abbreviation "LC", following the IUCN 2001 Categories & Criteria (version 3.1). Before 2001 "least concern" was a subcategory of the " Lower Risk" category and assigned the code "LR/lc" or lc. Around 20% of least concern taxa (3261 of 15,636) in the IUCN database still use the code "LR/lc", which indicates they have not been re- ...

International Union For Conservation Of Nature
The International Union for Conservation of Nature (IUCN) is an international organization working in the field of nature conservation and sustainable use of natural resources. Founded in 1948, IUCN has become the global authority on the status of the natural world and the measures needed to safeguard it. It is involved in data gathering and analysis, research, field projects, advocacy, and education. IUCN's mission is to "influence, encourage and assist societies throughout the world to conserve nature and to ensure that any use of natural resources is equitable and ecologically sustainable". Over the past decades, IUCN has widened its focus beyond conservation ecology and now incorporates issues related to sustainable development in its projects. IUCN does not itself aim to mobilize the public in support of nature conservation. It tries to influence the actions of governments, business and other stakeholders by providing information and advice and through building partners ...

Madre De Dios River
The Madre de Dios River () is a river shared by Bolivia and Peru which is homonymous to the Peruvian region it runs through. On Bolivian territory, it receives the Beni River, close to the town of Riberalta, which later joins with the Mamore River to become the Madeira River after the confluence. The Madeira is a tributary to the Amazon River. The Madre de Dios is an important waterway for the department of Madre de Dios, particularly Puerto Maldonado, the largest town in the area, and the capital of the department. Mango farming and gold mining are among the many industries on its banks. Other important industries the Madre de Dios provides are selective logging and farming, both of which are serious environmental problems. Along the length of the river, there are several national parks and reserves, notably Tambopata-Candamo National Park, Manu National Park (also known as Manu Biosphere Reserve) and Bahuaja-Sonene National Park. Hydrography The Madre de Dios serves as ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tambopata National Reserve
Tambopata National Reserve () is a Peruvian nature reserve located in the southeastern region of Madre de Dios. It was established on September 4, 2000, by decree of President Alberto Fujimori.

Napo River
The Napo River () is a tributary to the Amazon River that rises in Ecuador on the flanks of the east Andean volcanoes of Antisana, Sincholagua and Cotopaxi. The total length is . The river drains an area of ca 103,000 km2. The mean annual discharge at Mazán . Geography Before it reaches the plains it receives a great number of small streams from impenetrable, saturated and much broken mountainous districts, where the dense and varied vegetation seems to fight for every piece of ground. From the north it is joined by the Coca River, having its sources in the gorges of Cayambe volcano on the equator, and also a powerful river, the Aguarico having its headwaters between Cayambe and the Colombia frontier. From the west, it receives a secondary tributary, the Curaray, from the Andean slopes, between Cotopaxi and the Tungurahua volcano. From its Coca branch to the mouth of the Curaray the Napo is full of snags and shelving sandbanks and throws out numerous canoes among jung ...

Oxbow Lake
An oxbow lake is a U-shaped lake or stream pool, pool that forms when a wide meander of a river is meander cutoff, cut off, creating a free-standing body of water. The word "oxbow" can also refer to a U-shaped bend in a river or stream, whether or not it is cut off from the main stream. It takes its name from an oxbow which is part of a harness for oxen to pull a plough or cart. In South Texas, oxbows left by the Rio Grande are called ''resaca (channel), resacas''. In Australia, oxbow lakes are called billabongs. Geology An oxbow lake forms when a meandering river erodes through the neck of one of its meanders. This takes place because meanders tend to grow and become more curved over time. The river then follows a shorter course that bypasses the meander. The entrances to the abandoned meander eventually silt up, forming an oxbow lake. Oxbow lakes are stillwater lakes, with no current flowing through them, which causes the lake bed to gradually accumulate silt, becoming a ...
