Adolphe Delessert
Adolphe François Delessert (15 September 1809 – 6 April 1869) was a French explorer and naturalist. A nephew of Baron Benjamin Delessert, he accompanied Perrottet on a journey to India and Southeast Asia. During the course of five years that began on 24 April 1834, he collected several new species of plants and animals including the Wayanad laughingthrush which he collected on the slopes of the Nilgiris and was named by Thomas C. Jerdon as ''Garrulax delesserti'' in his honour. He travelled through Mauritius, Reunion Island, Penang, Pondicherry, Malay Peninsula, Singapore, Java, and Madras returning on 30 April 1839. He used German botanical artist Jean-Christophe Heyland (1791–1866), for some of the illustrations in his books. In 1843 he published a book ''Souvenirs d'un Voyage dans l'Inde exécuté de 1834 à 1839'' about his travels and included illustrations including landscapes by V. Dollet and animals by JG Prêtre.

Bumthang Valley
Bumthang Valley is the main inhabited valley in the Bumthang district of Bhutan. History Bumthang is one of the most beautiful and sacred valleys in Bhutan. The main town in the valley is Jakar. Bhutan's only brewery, brewing Red Panda wheat beer, is in Jakar. Bumthang is divided into four '' gewogs'', namely Chhoekhor, Tang, Chhume and Ura. The valley is broad with various habitats including coniferous woodland. The language spoken in Bumthang is known as Bumthang Kha, a Tibeto-Burman language. Each of the four valleys of Bumthang has its own dialect. Jampa Lhakhang The Jampa Lhakhang temple is located in the heart of Jakar Valley, it was built in the early 7th century by the dharma king Songtsen Gempo. He commissioned the creation of 108 temples at the same time to successive circles in order to pin down and evil demoness who was seen to be blocking the spread of Buddhism. This monastery is one of two such temples that survive in Bhutan. the other being Kichu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Magpie
Magpies are birds of various species of the family Corvidae. Like other members of their family, they are widely considered to be intelligent creatures. The Eurasian magpie, for instance, is thought to rank among the world's most intelligent creatures, and is one of the few nonmammalian species able to recognize itself in a mirror test. Magpies have shown the ability to make and use tools, imitate human speech, grieve, play games, and work in teams. They are particularly well known for their songs and were once popular as cagebirds. In addition to other members of the genus '' Pica'', corvids considered magpies are in the genera '' Cissa'', '' Urocissa'', and '' Cyanopica''. Magpies of the genus ''Pica'' are generally found in temperate regions of Europe, Asia, and western North America, with populations also present in Tibet and high-elevation areas of Kashmir. Magpies of the genus ''Cyanopica'' are found in East Asia and the Iberian Peninsula. The birds called magpies in Au ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Eurasian Magpie
The Eurasian magpie or common magpie (''Pica pica'') is a resident breeding bird throughout the northern part of the Eurasian continent. It is one of several birds in the crow family (corvids) designated magpies, and belongs to the Holarctic radiation of "monochrome" magpies. In Europe, "magpie" is used by English speakers as a synonym for the Eurasian magpie: the only other magpie in Europe is the Iberian magpie (''Cyanopica cooki''), which is limited to the Iberian Peninsula. Despite having a shared name and similar colouration, it is not closely related to the Australian magpie. The Eurasian magpie is one of the most intelligent birds. The expansion of its nidopallium is approximately the same in its relative size as the brain of chimpanzees, gorillas, orangutans and humans. It is the only non-mammalian species known to pass the mirror test. Taxonomy and systematics The magpie was described and illustrated by Swiss naturalist Conrad Gessner in his '' Historiae animali ...

Molecular Phylogenetic
Molecular phylogenetics () is the branch of phylogeny that analyzes genetic, hereditary molecular differences, predominantly in DNA sequences, to gain information on an organism's evolutionary relationships. From these analyses, it is possible to determine the processes by which diversity among species has been achieved. The result of a molecular phylogenetic analysis is expressed in a phylogenetic tree. Molecular phylogenetics is one aspect of molecular systematics, a broader term that also includes the use of molecular data in taxonomy and biogeography. Molecular phylogenetics and molecular evolution correlate. Molecular evolution is the process of selective changes (mutations) at a molecular level (genes, proteins, etc.) throughout various branches in the tree of life (evolution). Molecular phylogenetics makes inferences of the evolutionary relationships that arise due to molecular evolution and results in the construction of a phylogenetic tree.

Sister Taxon
In phylogenetics, a sister group or sister taxon, also called an adelphotaxon, comprises the closest relative(s) of another given unit in an evolutionary tree. Definition The expression is most easily illustrated by a cladogram: Taxon A and taxon B are sister groups to each other. Taxa A and B, together with any other extant or extinct descendants of their most recent common ancestor (MRCA), form a monophyletic group, the clade AB. Clade AB and taxon C are also sister groups. Taxa A, B, and C, together with all other descendants of their MRCA form the clade ABC. The whole clade ABC is itself a subtree of a larger tree which offers yet more sister group relationships, both among the leaves and among larger, more deeply rooted clades. The tree structure shown connects through its root to the rest of the universal tree of life. In cladistic standards, taxa A, B, and C may represent specimens, species, genera, or any other taxonomic units. If A and B are at the same taxonomic ...

Asir Magpie
The Asir magpie (''Pica asirensis''), also known as the Arabian magpie, is a highly endangered species of magpie endemic to Saudi Arabia. It is only found in the country's southwestern highlands, in the Asir Region. It occurs only in African juniper forest in well-vegetated wadis and valleys. It was formerly classified as a subspecies of the Eurasian magpie (''Pica pica''), and still is by many authorities. This species is highly threatened by habitat destruction, as its native forests are not regenerating. Tourism development and climate change are also posing a threat. Only 135 pairs (270 mature individuals) are known to survive in the wild, and this number is declining. A molecular phylogenetic study published in 2018 found that the Asir magpie was a sister taxon to the black-rumped magpie that is found on the Tibetan Plateau. Description The Asir magpie (''Pica asirensis'') is about long, and its approximate weight is . Its head, neck, back, front chest, and feet are al ...

Pica (genus)
''Pica'' is a genus of seven species of birds in the family Corvidae in both the New World and the Old. It is one of several corvid genera whose members are known as magpies. ''Pica'' have long tails and predominantly black and white markings. After ''Corvus'', this genus is the second most widespread within the Corvidae family, being distributed across Eurasia, north Africa, and western North America. Molecular phylogeny suggests that ''Pica'' is most closely related to nutcrackers (''Nucifraga''), jackdaws ('' Coloeus'') and crows and ravens ('' Corvus''). Taxonomy The genus ''Pica'' was introduced by the French zoologist Mathurin Jacques Brisson in 1760. He derived the name by tautonymy from the specific epithet of the Eurasian magpie ''Corvus pica'' which was introduced by Linnaeus in 1758. ''Pica'' is the Latin word for the Eurasian magpie. In 2018, a molecular phylogenetic study found that the Eurasian magpie consisted of multiple species including the Maghreb magpie, ...

Birds are a group of warm-blooded vertebrates constituting the class (biology), class Aves (), characterised by feathers, toothless beaked jaws, the Oviparity, laying of Eggshell, hard-shelled eggs, a high Metabolism, metabolic rate, a four-chambered heart, and a strong yet lightweight Bird skeleton, 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 Order (biology), orders. More than half are passerine or "perching" birds. Birds have Bird wing, wings whose development varies according to species; the only known groups without wings are the extinct moa and elephant birds.
