Coquerel's Coua
Coquerel's coua (''Coua coquereli'') is a species of cuckoo in the family Cuculidae. It is Endemism, endemic to Madagascar. Its habitat is subtropical or tropical dry forests. It was named in 1867 by the French naturalist Alfred Grandidier in honor of the French navy surgeon and naturalist Charles Coquerel. Description Coquerel's coua is approximately in length and has a large blue patch of bare skin around the eye, a characteristic of the ''Coua'' genus that is similar to African turacos. The plumage is silky, the crown is black, the upper parts and tail are light brown or greyish-brown, and the lower breast and belly is suffused with red. The iris is red and the beak and legs are slaty grey. As a member of the cuckoo family, it has a reversible third toe and resembles the coucal in its method of scrambling through tangled bushes and lianas while searching for food. Observations indicate that it can climb about above the ground. Distribution and habitat Coquerel's coua is Ende ...

Alfred Grandidier
Alfred Grandidier (20 December 1836 – 13 September 1921) was a French natural history, naturalist and List of explorers, explorer. From a very wealthy family, at the age of 20, he and his brother, Ernest Grandidier (1833–1912), undertook a voyage around the world. At first they were led by the astronomer and physicist Pierre Jules César Janssen (1824–1907), but when Janssen fell sick and had to return to France after about six months, the brothers continued the journey. They visited South America in 1858 and 1859 and in particular the Andes, Peru, Chile, Bolivia, Argentina and Brazil. During this voyage they gathered a significant collection of specimens which were analyzed, in 1860, by Ernest. The two brothers parted ways after this. Ernest Grandidier went to China and collected a vast number of specimens which are now in the Louvre and the Guimet Museum, Guimet museum. Alfred travelled to India, reaching it in 1863. He had intended to explore the high plateau of Tibet ...

Monogamy In Animals
Some animal species have a monogamous mating system, in which pairs bond to raise offspring. This is associated, usually implicitly, with sexual monogamy. Monogamous mating Monogamy is defined as a pair bond between two adult animals of the same species. This pair may cohabitate in an area or territory for some duration of time, and in some cases may copulate and reproduce with only each other. Monogamy may either be short-term, lasting one to a few seasons or long-term, lasting many seasons and in extreme cases, life-long. Monogamy can be partitioned into two categories, social monogamy and genetic monogamy which may occur together in some combination, or completely independently of one another.Ophir, Alexander G., Phelps, Steven M., Sorin, Anna Bess & O. Wolff, J. (2008)Social but not genetic monogamy is associated with greater breeding success in prairie voles/ref> As an example, in the cichlid species '' Variabilichromis moorii'', a monogamous pair will care for eggs and y ...

Taxa Named By Alfred Grandidier
In biology, a taxon (back-formation from ''taxonomy''; : taxa) is a group of one or more populations of an organism or organisms seen by taxonomists to form a unit. Although neither is required, a taxon is usually known by a particular name and given a particular ranking, especially if and when it is accepted or becomes established. It is very common, however, for taxonomists to remain at odds over what belongs to a taxon and the criteria used for inclusion, especially in the context of rank-based (" Linnaean") nomenclature (much less so under phylogenetic nomenclature). If a taxon is given a formal scientific name, its use is then governed by one of the nomenclature codes specifying which scientific name is correct for a particular grouping. Initial attempts at classifying and ordering organisms (plants and animals) were presumably set forth in prehistoric times by hunter-gatherers, as suggested by the fairly sophisticated folk taxonomies. Much later, Aristotle, and later still ...

Endemic Birds Of Madagascar
Endemism is the state of a species being found only in a single defined geographic location, such as an island, state, nation, country or other defined zone; organisms that are indigenous to a place are not endemic to it if they are also found elsewhere. For example, the Cape sugarbird is found exclusively in southwestern South Africa and is therefore said to be ''endemic'' to that particular part of the world. An endemic species can also be referred to as an ''endemism'' or, in scientific literature, as an ''endemite''. Similarly, many species found in the Western ghats of India are examples of endemism. Endemism is an important concept in conservation biology for measuring biodiversity in a particular place and evaluating the risk of extinction for species. Endemism is also of interest in evolutionary biology, because it provides clues about how changes in the environment cause species to undergo range shifts (potentially expanding their range into a larger area or becomin ...

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 ...

Cuckoo Roller
The cuckoo-roller or courol (''Leptosomus discolor'')del Hoyo, J. Elliott, A. & Sargatal, J. (2001) is the only bird in the family Leptosomidae , which was previously often placed in the order Coraciiformes but is now placed in its own order Leptosomiformes. The cuckoo-roller is at the root of a group that contains the Trogoniformes, Bucerotiformes, Piciformes, and Coraciiformes. Despite its name, the Cuckoo-roller does not share close evolutionary origins with cuckoos or rollers. It is a medium-large bird, inhabiting forests and woodlands in Madagascar and the Comoro Islands. Three subspecies are described: the nominate ''L. d. discolor'' is found in Madagascar and Mayotte Island, ''L. d. intermedius'' on Anjouan, and ''L. d. gracilis'' of Grand Comoro. Based on its smaller size, differences in the plumage, and minor difference in the voice, the last of these is sometimes considered a separate species, the Comoro cuckoo-roller (''L. gracilis''). Description The cuckoo-ro ...

Leioheterodon Madagascariensis
''Leioheterodon madagascariensis'', the Malagasy, Madagascar or Madagascan giant hognose (snake), is a harmless species of pseudoxyrhophiid snake endemic to the island nation of Madagascar. The species is also found on the country's smaller islands of Nosy Be, Nosy Mangabe, and Nosy Sakatia, as well as on the Comoros archipelago, in the Mozambique Channel. It is thought, by some, to have been introduced to the Grande Comoro. Mature giant hognose snakes can measure between 130 and 180 cm (4 ft. to nearly 6 ft., or between 1-2 meters) in length, and be roughly the thickness of an average adult human's arm. Similarly to the ''Heterodon'' or ''Lystrophis'' genera of new-world hognoses, the Madagascar giant hognose, when threatened, will raise its head, open its mouth and inflate the skin around its neck and chin, superficially mimicking a cobra (or even a bearded dragon) in defensive posture, in an attempt to look larger and more intimidating. This snake is considered to be o ...

Common Brown Lemur
The common brown lemur (''Eulemur fulvus'') is a species of lemur in the family Lemuridae. It is found in Madagascar and has been introduced to Mayotte. Taxonomy Five additional currently recognized species of lemur were until 2001 considered subspecies of ''E. fulvus''. These are: * White-fronted brown lemur, ''E. albifrons'' * Gray-headed lemur, ''E. cinereiceps'' * Collared brown lemur, ''E. collaris'' * Red-fronted brown lemur, ''E. rufus'' * Sanford's brown lemur, ''E. sanfordi'' However, a number of zoologists believe that ''E. albifrons'' and ''E. rufus'' should continue to be considered subspecies of ''E. fulvus''. Physical description The common brown lemur has a total length of , including of tail. Weight ranges from . Common brown lemurs are unique amongst ''Eulemur'' in that they exhibit little-to-no sexual dichromatism: in both males and females, the face, muzzle and crown are dark gray or black, with white or tan "cheeks" of varying thickness. Some individuals m ...

Small Indian Civet
The small Indian civet (''Viverricula indica'') is a civet native to South and Southeast Asia. It is listed as Least Concern on the IUCN Red List because of its widespread distribution, widespread habitat use and healthy populations living in agricultural and secondary landscapes of many range states. This is the only species in genus ''Viverricula''. Characteristics The small Indian civet has a rather coarse fur that is brownish grey to pale yellowish brown, with usually several longitudinal black or brown bands on the back and longitudinal rows of spots on the sides. Usually there are five or six distinct bands on the back and four or five rows of spots on each side. Some have indistinct lines and spots, with the dorsal bands wanting. Generally there are two dark stripes from behind the ear to the shoulders, and often a third in front, crossing the throat. Its underfur is brown or grey, often grey on the upper parts of the body and brown on the lower. The grey hairs on the u ...
