Moluccan megapode

The Moluccan megapode (Eulipoa wallacei), also known as Wallace's scrubfowl, Moluccan scrubfowl or painted megapode, is a small, approximately 31 cm long, olive-brown megapode. The genus Eulipoa is monotypic, but the Moluccan megapode is sometimes placed in Megapodius instead. Both sexes are similar with an olive-brown plumage, bluish-grey below, white undertail coverts, brown iris, bare pink facial skin, bluish-yellow bill and dark olive legs. There are light grey stripes on reddish-maroon feathers on its back. The young has brownish plumage, a black bill, legs and hazel iris.

An Indonesian endemic, the Moluccan megapode is confined to hill and mountain forests on the Maluku Islands of Halmahera, Buru, Seram, Ambon, Ternate, Haruku and Bacan. It also found on Misool Island in West Papua province.

The Moluccan megapode is the only megapode known to lay its eggs nocturnally. The nesting grounds are usually located in sun-exposed beach or volcanic soils.

Due to ongoing habitat loss, limited range and overhunting in some areas, the Moluccan megapode is evaluated as Vulnerable on the IUCN Red List of Threatened Species.

Buru

Buru (formerly spelled Boeroe, Boro, or Bouru) is the third largest island within Maluku Islands of Indonesia. It lies between the Banda Sea to the south and Seram Sea to the north, west of Ambon and Seram islands. The island belongs to Maluku province (Indonesian: Provinsi Maluku) and includes the Buru (Indonesian: Kabupaten Buru) and South Buru (Indonesian: Kabupaten Buru Selatan) regencies. Their administrative centers, Namlea and Namrole, respectively, have ports and the largest towns of the island. There is a military airport at Namlea which supports civilian cargo transportation.

About a third of the population is indigenous, mostly Buru, but also Lisela, Ambelau and Kayeli people. The rest of population are immigrants from Java and nearby Maluku Islands. Religious affiliation is evenly split between Christianity and Sunni Islam, with some remnants of traditional beliefs. While local languages and dialects are spoken within individual communities, the national Indonesian language is used among the communities and by the administration. Most of the island is covered with forests rich in tropical flora and fauna. From the present 179 bird and 25 mammal species, about 14 are found either on Buru only or also on a few nearby islands, the most notable being the wild pig Buru babirusa. There is little industry on the island, and most population is engaged in growing rice, maize, sweet potato, beans, coconuts, cocoa, coffee, clove and nutmeg. Other significant activities are animal farming and fishing.

The island was first mentioned around 1365. Between 1658 and 1942, it was colonised by the Dutch East India Company and then by the Crown of the Netherlands. The Dutch administration relocated many local villages to the newly built island capital at Kayeli Bay for working at clove plantations. It also promoted the hierarchy among the indigenous people with selected loyal rajas placed above the heads of the local clans. The island was occupied by the Japanese forces between 1942 and 1945 and in 1950 became part of independent Indonesia. During former president Suharto's New Order administration in the 1960s–1970s, Buru was the site of a prison used to hold thousands of political prisoners. While held at Buru, writer Pramoedya Ananta Toer wrote most of his novels, including Buru Quartet.

List of Galliformes

The Galliformes are a clade of bird species of cosmopolitan distribution that, with the Anseriformes, belong to the branch Galloanserae. The group have more than 270 living species and includes the megapodes, chachalacas, guans, curassows, turkeys, grouse, New World quails, pheasants, partridges and guineafowl. They are, with Neoaves, the two main lineages of Neognathae. Extinct species assignment follows the Mikko's Phylogeny Archive and Paleofile.com websites.

List of Galliformes by population

This is a list of Galliformes species by global population. While numbers are estimates, they have been made by the experts in their fields. For more information on how these estimates were ascertained, see Wikipedia's articles on population biology and population ecology.

This list is not comprehensive, as not all Galliformes have had their numbers quantified.

List of bird genera

List of bird genera concerns the chordata class of aves or birds, characterised by feathers, a beak with no teeth, the laying of hard-shelled eggs, and a high metabolic rate.

List of birds by common name

In this list of birds by common name, a total of 9,722 extant and recently extinct bird species are recognised, belonging to a total of 204 families.

List of vulnerable birds

As of May 2019, the International Union for Conservation of Nature (IUCN) lists 799 vulnerable avian species. 7.1% of all evaluated avian species are listed as vulnerable.

No subpopulations of birds have been evaluated by the IUCN.

For a species to be assessed as vulnerable to extinction the best available evidence must meet quantitative criteria set by the IUCN designed to reflect "a high risk of extinction in the wild". Endangered and critically endangered species also meet the quantitative criteria of vulnerable species, and are listed separately. See: List of endangered birds, List of critically endangered birds. Vulnerable, endangered and critically endangered species are collectively referred to as threatened species by the IUCN.

Additionally 61 avian species (0.59% of those evaluated) are listed as data deficient, meaning there is insufficient information for a full assessment of conservation status. As these species typically have small distributions and/or populations, they are intrinsically likely to be threatened, according to the IUCN. While the category of data deficient indicates that no assessment of extinction risk has been made for the taxa, the IUCN notes that it may be appropriate to give them "the same degree of attention as threatened taxa, at least until their status can be assessed."This is a complete list of vulnerable avian species evaluated by the IUCN. Where possible common names for taxa are given while links point to the scientific name used by the IUCN.

Megapode

The megapodes, also known as incubator birds or mound-builders, are stocky, medium-large, chicken-like birds with small heads and large feet in the family Megapodiidae. Their name literally means "large foot" (Greek: mega = large, poda = foot), and is a reference to the heavy legs and feet typical of these terrestrial birds. All are browsers, and all but the malleefowl occupy wooded habitats. Most are brown or black in color. Megapodes are superprecocial, hatching from their eggs in the most mature condition of any bird. They hatch with open eyes, bodily coordination and strength, full wing feathers, and downy body feathers, and are able to run, pursue prey, and in some species, fly on the same day they hatch.

Scrubfowl

The scrubfowl are the genus Megapodius of the mound-builders, stocky, medium-large chicken-like birds with small heads and large feet in the family Megapodiidae. They are found from south-east Asia to north Australia and islands in the west Pacific.

They do not incubate their eggs with their body heat in the orthodox way, but bury them. They are best known for building a massive mound of decaying vegetation, which the male attends, adding or removing litter to regulate the internal heat while the eggs hatch. The species in taxonomic order are:

†Pile-builder scrubfowl (Megapodius molistructor)

†Viti Levu scrubfowl (Megapodius amissus)In all of the above, the name "scrubfowl" is sometimes exchanged with "megapode". Traditionally, most have been listed as subspecies of M. freycinet, but today all major authorities consider this incorrect. Nevertheless, there are unresolved issues within the genus, and for example the taxon forstenii has been considered a subspecies of M. freycinet, a subspecies of M. cumingii, or a monotypic species. An additional species, the Moluccan megapode, has sometimes been placed in Megapodius, but today most place it in the genus Eulipoa instead. The maleo is also associated with these genera, and together the three form a group.

Tremp Formation

The Tremp Formation (Spanish: Formación de Tremp, Catalan: Formació de Tremp), alternatively described as Tremp Group (Spanish: Grupo Tremp), is a geological formation in the comarca Pallars Jussà, Lleida, Spain. The formation is restricted to the Tremp or Tremp-Graus Basin (Catalan: Conca de Tremp), a piggyback foreland basin in the Catalonian Pre-Pyrenees. The formation dates to the Maastrichtian to Thanetian, thus the formation includes the Cretaceous-Paleogene boundary that has been well studied in the area, using paleomagnetism and carbon and oxygen isotopes. The formation comprises several lithologies, from sandstone, conglomerates and shales to marls, siltstones, limestones and lignite and gypsum beds and ranges between 250 and 800 metres (820 and 2,620 ft) in thickness. The Tremp Formation was deposited in a continental to marginally marine fluvial-lacustrine environment characterized by estuarine to deltaic settings.

The Tremp Basin evolved into a sedimentary depression with the break-up of Pangea and the spreading of the North American and Eurasian Plates in the Early Jurassic. Rifting between Africa and Europe in the Early Cretaceous created the isolated Iberian microplate, where the Tremp Basin was located in the northeastern corner in a back-arc basin tectonic regime. Between the middle Albian and early Cenomanian, a series of pull-apart basins developed, producing a local unconformity in the Tremp Basin. A first phase of tectonic compression commenced in the Cenomanian, lasting until the late Santonian, around 85 Ma, when Iberia started to rotate counterclockwise towards Europe, producing a series of piggyback basins in the southern Pre-Pyrenees. A more tectonically quiet posterior phase provided the Tremp Basin with a shallowing-upward sequence of marine carbonates until the moment of deposition of the Tremp Formation, in the lower section still marginally marine, but becoming more continental and lagoonal towards the top.

Shortly after deposition of the Tremp Formation, the Boixols Thrust, active to the north of the Tremp Basin and represented by the Sant Corneli anticline, started a phase of tectonic inversion, placing upper Santonian rocks on top of the northern Tremp Formation. The main phase of movement of another major thrust fault, the Montsec to the south of the Tremp Basin, happened not before the Early Eocene. Subsequently, the western Tremp Basin was covered by thick layers of conglomerates, creating a purely continental foreland basin, a trend observed going westward in the neighboring foreland basins of Ainsa and Jaca.

A rich and diverse assemblage of fossils has been reported from the formation, among which more than 1000 dinosaur bones, tracks dating up to just 300,000 years before the Cretaceous-Paleogene boundary, and many well-preserved eggs and nesting sites in situ, spread out over an area of 6,000 square metres (65,000 sq ft). Multiple specimens and newly described genera and species of crocodylians, mammals, turtles, lizards, amphibians and fish complete the rich vertebrate faunal assemblage of the Tremp Formation. Additionally, fresh-to-brackish water clams as Corbicula laletana, bivalves of Hippurites castroi, gastropods, plant remains and cyanobacteria as Girvanella were found in the Tremp Formation. The unique paleoenvironment, well-exposed geology, and importance as national heritage has sparked proposals to designate the Tremp Formation and its region as a protected geological site of interest since 2004, much like the Aliaga geological park and others in Spain.Due to the exposure, the interaction of tectonics and sedimentation and access, the formation is among the best studied stratigraphic units in Europe, with many universities performing geological fieldwork and professional geologists studying the different lithologies of the Tremp Formation. The abundant paleontological finds are displayed in the local natural science museums of Tremp and Isona, where educational programs have been established explaining the geology and paleobiology of the area. In 2016, the Tremp Basin and surrounding areas were filed to become a Global Geopark, and on April 17, 2018, UNESCO accepted this proposal and designated the site Conca de Tremp-Montsec Global Geopark. Spain hosts the second-most Global Geoparks in the world, after China.
