Peruvian Pelican
The Peruvian pelican (''Pelecanus thagus'') is a member of the pelican family. It lives on the west coast of South America, breeding in loose colonies from about 33.5° in central Chile to Piura in northern Peru, and occurring as a visitor in southern Chile and Ecuador. Handbook of the Birds of the World AlivePeruvian pelican.Retrieved 21 May 2017. Description These birds are dark in colour with a white stripe from the top of the bill up to the crown and down the sides of the neck. They have long tufted feathers on the top of their heads.

Juan Ignacio Molina
Fr. Juan Ignacio Molina (; (June 24, 1740 – September 12, 1829) was a Chilean Jesuit priest, naturalist, historian, translator, geographer, botanist, ornithologist, and linguist. He is usually referred to as Abate Molina (a form of Abbot Molina), and is also sometimes known by the Italian form of his name, Giovanni Ignazio Molina. He was one of the precursors of the theory of the gradual evolution of species, 44 years before Darwin, who repeatedly quoted him in "The Origin of Species". Biography Early years Molina was born at Guaraculén, a big farm located near Villa Alegre (General Captaincy of Chile), where he lived until he was 5 years old. In the current province of Linares, in the Maule Region of Chile. His parents were Agustín Molina and Francisca González Bruna. From an early age he was attracted to the nature of his environment, and in addition to his school work, he enjoyed observing nature on the family farm, which he visited periodically, alternating with ...

Avian Clutch Size
Clutch size refers to the number of eggs laid in a single brood by a nesting pair of birds. The numbers laid by a particular species in a given location are usually well defined by evolutionary trade-offs with many factors involved, including resource availability and energetic constraints. Several patterns of variation have been noted and the relationship between latitude and clutch size has been a topic of interest in avian reproduction and evolution. David Lack and R.E. Moreau were among the first to investigate the effect of latitude on the number of eggs per nest. Since Lack's first paper in the mid-1940s there has been extensive research on the pattern of increasing clutch size with increasing latitude. The proximate and ultimate causes for this pattern have been a subject of intense debate involving the development of ideas on group, individual, and gene-centric views of selection. Food limitation and nest predation hypotheses David Lack observed a direct relationship ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ballestas Islands
The Ballestas Islands (Spanish: ''Islas Ballestas'') are a group of small islands near the town of Paracas within the Paracas District of the Pisco Province in the Ica Region, on the south coast of Peru. Geography Composed largely of rock formations and covering an estimated area of 0.12 km², these islands are an important sanctuary for marine fauna like the guanay guano bird, the blue-footed booby and the tendril. Other notable species include Humboldt penguins and two varieties of seals (fur seals and sea lions), amongst other mammals. Access These islands are accessible from the resort town of Paracas (near Pisco) by tour boat which typically lasts 2 hours. During the visits it is not uncommon for the sea lions to approach the tourist boats and make spectacles for the visiting tourists.

Near Threatened
A near-threatened species is a species which has been categorized as "Near Threatened" (NT) by the International Union for Conservation of Nature as that may be vulnerable to endangerment in the near future, but it does not currently qualify for the threatened status. The IUCN notes the importance of re-evaluating near-threatened taxon at appropriate intervals. The rationale used for near-threatened taxa usually includes the criteria of vulnerable which are plausible or nearly met, such as reduction in numbers or range. Near-threatened species evaluated from 2001 onwards may also be ones which are dependent on conservation efforts to prevent their becoming threatened, whereas before this conservation-dependent species were given a separate category ("Conservation Dependent"). Additionally, the 402 conservation-dependent taxa may also be considered near-threatened.

IUCN Red List
The International Union for Conservation of Nature (IUCN) Red List of Threatened Species, also known as the IUCN Red List or Red Data Book, founded in 1964, is the world's most comprehensive inventory of the global conservation status of biological species. It uses a set of precise criteria to evaluate the extinction risk of thousands of species and subspecies. These criteria are relevant to all species and all regions of the world. With its strong scientific base, the IUCN Red List is recognized as the most authoritative guide to the status of biological diversity. A series of Regional Red Lists are produced by countries or organizations, which assess the risk of extinction to species within a political management unit. The aim of the IUCN Red List is to convey the urgency of conservation issues to the public and policy makers, as well as help the international community to reduce species extinction. According to IUCN the formally stated goals of the Red List are to provi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cannibalism (zoology)
Cannibalism is the act of consuming another individual of the same species as food. Cannibalism is a common ecological interaction in the animal kingdom and has been recorded in more than 1,500 species. Human cannibalism is well documented, both in ancient and in recent times. The rate of cannibalism increases in nutritionally poor environments as individuals turn to members of their own species as an additional food source.Elgar, M.A. & Crespi, B.J. (1992) ''Cannibalism: ecology and evolution among diverse taxa'', Oxford University Press, Oxford ngland New York. Cannibalism regulates population numbers, whereby resources such as food, shelter and territory become more readily available with the decrease of potential competition. Although it may benefit the individual, it has been shown that the presence of cannibalism decreases the expected survival rate of the whole population and increases the risk of consuming a relative. Other negative effects may include the increased ri ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gray Gull
The grey gull, also known as garuma gull (''Leucophaeus modestus'') is a medium-sized gull native to South America. Unusual among gulls, it breeds inland in the extremely dry Atacama Desert in northern Chile, although it is present as a non-breeding bird along much of the Pacific coast of South America. Description The sexes are similar in grey gulls. Adults grow to a length of about and weigh some . The head is white in summer but brownish-grey in winter. The body and wings are grey with the dorsal surface rather darker than the ventral region. The flight feathers are black and the inner primaries and the secondaries have white tips, visible in flight. The tail has a band of black with a white trailing edge. The legs and beak are black and the iris is brown.Josep del Hoyo, Andrew Elliott, Jordi Sargatal (Eds.): ''Handbook of the Birds of the World''. Volume 3: Hoatzin to Auks. Lynx Edicions 1996, , p. 602 The call is similar to that of the laughing gull (''Leucophaeus atricilla ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Peruvian Diving Petrel
The Peruvian diving petrel (''Pelecanoides garnotii'') (local name in Peru: potoyunco) is a small seabird that feeds in offshore waters in the Humboldt Current off Peru and Chile. Taxonomy The Peruvian diving petrel was formally described in 1828 by the French naturalists René Lesson and Prosper Garnot under the binomial name ''Puffinuria garnotti''. In his book ''Manuel d'ornithologie'' Lesson quotes the text of a description written by Garnot. The Peruvian diving petrel is now placed in the genus '' Pelecanoides'' was originally introduced in 1799 by the French naturalist Bernard Germain de Lacépède for the common diving petrel. Page numbering starts at one for each of the three sections. The species is monotypic: no subspecies are recognised. Description Peruvian diving petrel is in overall length. Like the rest of the diving petrels it is a nondescript bird, with a dark back and pale belly, and blue feet, and can be separated from the rest of its family only by differenc ...

Imperial Shag
The imperial shag or imperial cormorant (''Leucocarbo atriceps'') is a black and white cormorant native to southern South America, primarily in rocky coastal regions, but locally also at large inland lakes. Some taxonomic authorities, including the International Ornithologists' Union, place it in the genus ''Leucocarbo'', others in the genus ''Phalacrocorax''. It is also known as the blue-eyed shag, blue-eyed cormorant and by many other names, and is one of a larger group of cormorants called blue-eyed shags. The taxonomy is very complex, and several former subspecies are often considered separate species. Taxonomy The taxonomy is very complex and species-limits within this group remain unresolved. Some taxonomic authorities, including the International Ornithologists' Union, split the group into the species listed below. Others consider the all or part of the group conspecific. The following are considered part of this group: * Imperial shag, ''Leucocarbo (atriceps) atriceps'', ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
