Sevan National Park
Sevan National Park, is one of the four protected national parks of Armenia, founded in 1978 to protect Lake Sevan and the surrounding areas. It is under the jurisdiction of the Ministry of Environment and includes a research center, which monitors the ecosystems, and undertakes various conservation measures. Licensed fishing on the lake is also regulated. Fauna Mammals Scientific knowledge about the mammals of the Sevan basin is quite poor and fragmental. Wolf, jackal, fox, marten, cat, hare, small rodents are usually mentioned. Avifauna Sevan lake and its vicinity are rich in avifauna. Up to 267 bird species have been recorded in Sevan Basin. The known avifauna can be grouped into the orders: Podicipediformes, Pelecaniformes, Phoenicopteriformes, Falconiformes, Anseriformes, Galliformes, Gruiformes, Charadriiformes, Columbiformes, Cuculiformes, Strigiformes, Caprimulgiformes, Apodiformes, Coraciiformes, Piciformes, and Passeriformes. 56 species are included in the Red Boo ...

Gegharkunik Province
Gegharkunik ( hy, Գեղարքունիք, ) is a province ('' marz'') of Armenia. Its capital and largest city is Gavar. Gegharkunik Province is located at the eastern part of Armenia, bordering Azerbaijan. It includes the exclave of Artsvashen, which has been under Azerbaijani occupation since the First Nagorno-Karabakh War. With an area of , Gegharkunik is the largest province in Armenia. However, approximately 24% or of its territory is covered by Lake Sevan, the largest lake in the South Caucasus and a major tourist attraction of the region. The Yerevan-Sevan-Dilijan republican highway runs through the province. Etymology and symbols The early Armenian history Movses Khorenatsi connected the name of Gegharkunik with Gegham, a 5th-generation descendant of the legendary patriarch and founder of the Armenian nation Hayk. Gegham was the father of Sisak (founder of the Siunia dynasty) and Harma (grandfather of Ara the Beautiful). The Gegham Mountains and the Lake of Gegham ( ...

Falconiformes
The order Falconiformes () is represented by the extant family Falconidae (falcons and caracaras) and a handful of enigmatic Paleogene species. Traditionally, the other bird of prey families Cathartidae (New World vultures and condors), Sagittariidae (secretarybird), Pandionidae (ospreys), Accipitridae (hawks) were classified in Falconiformes. A variety of comparative genome analysis published since 2008, however, found that falcons are part of a clade of birds called Australaves, which also includes seriemas, parrots and passerines. Within Australaves falcons are more closely related to the parrot-passerine clade (Psittacopasserae), which together they form the clade Eufalconimorphae. The hawks and vultures occupy a basal branch in the clade Afroaves in their own clade Accipitrimorphae, closer to owls and woodpeckers. See below cladogram of Telluraves relationships based on Braun & Kimball (2021): The fossil record of Falconiformes ''sensu stricto'' is poorly documented. ...

Armenian Gull
__NOTOC__ The Armenian gull (''Larus armenicus'') is a large gull found in the Caucasus and the Middle East. It was formerly classified as a subspecies of the European herring gull (''L. argentatus''), but is now generally considered to be a separate species, although BirdLife International lumps it with the yellow-legged gull (''L. michahellis''). Description The Armenian gull is a fairly large gull species, though it is on average the smallest of the "herring gull" complex. It can range from , from across the wings, and weighs from . Among standard measurements, its wing chord is , its bill is and its tarsus is .''Gulls of North America, Europe, and Asia'' by Klaus Malling Olsen & Hans Larsson. Princeton University Press (2004). . They are superficially similar to yellow-legged gulls but are slightly smaller with a slightly darker grey back and dark eyes. The area of black on the wingtips is more extensive with smaller white spots. The bill is short with a distinctive blac ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Passeriformes
A passerine () is any bird of the order Passeriformes (; from Latin 'sparrow' and '-shaped'), which includes more than half of all bird species. Sometimes known as perching birds, passerines are distinguished from other orders of birds by the arrangement of their toes (three pointing forward and one back), which facilitates perching. With more than 140 families and some 6,500 identified species, Passeriformes is the largest clade of birds and among the most diverse clades of terrestrial vertebrates, representing 60% of birds.Ericson, P.G.P. et al. (2003Evolution, biogeography, and patterns of diversification in passerine birds ''J. Avian Biol'', 34:3–15.Selvatti, A.P. et al. (2015"A Paleogene origin for crown passerines and the diversification of the Oscines in the New World" ''Molecular Phylogenetics and Evolution'', 88:1–15. Passerines are divided into three clades: Acanthisitti (New Zealand wrens), Tyranni (suboscines), and Passeri (oscines or songbirds). The passerin ...

Piciformes
Nine families of largely arboreal birds make up the order Piciformes , the best-known of them being the Picidae, which includes the woodpeckers and close relatives. The Piciformes contain about 71 living genera with a little over 450 species, of which the Picidae (woodpeckers and relatives) make up about half. In general, the Piciformes are insectivorous, although the barbets and toucans mostly eat fruit and the honeyguides are unique among birds in being able to digest beeswax (although insects make up the bulk of their diet). Nearly all Piciformes have parrot-like zygodactyl feet—two toes forward and two back, an arrangement that has obvious advantages for birds that spend much of their time on tree trunks. An exception are a few species of three-toed woodpeckers. The jacamars aside, Piciformes do not have down feathers at any age, only true feathers. They range in size from the rufous piculet at 8 centimetres in length, and weighing 7 grams, to the toco toucan, at ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Coraciiformes
The Coraciiformes are a group of usually colourful birds including the kingfishers, the bee-eaters, the rollers, the motmots, and the todies. They generally have syndactyly, with three forward-pointing toes (and toes 3 & 4 fused at their base), though in many kingfishers one of these is missing. The members of this order are linked by their “slamming” behaviour, thrashing their prey onto surfaces to disarm or incapacitate them. This is largely an Old World order, with the representation in the New World limited to the dozen or so species of todies and motmots, and a mere handful of the more than a hundred species of kingfishers. The name Coraciiformes means " raven-like". Specifically, it comes from the Latin language "corax", meaning "raven" and Latin "forma", meaning "form", which is the standard ending for bird orders. Systematics This order has been seen to be something of a mixed assortment, and the Coraciiformes may be considered as including only the rollers. ...

Apodiformes
Traditionally, the bird order Apodiformes contained three living families: the swifts (Apodidae), the treeswifts (Hemiprocnidae), and the hummingbirds (Trochilidae). In the Sibley-Ahlquist taxonomy, this order is raised to a superorder Apodimorphae in which hummingbirds are separated as a new order, Trochiliformes. With nearly 450 species identified to date, they are the most diverse order of birds after the passerines. Description As their name ("footless" in Greek) suggests, their legs are small and have limited function aside from perching. The feet are covered with bare skin rather than the scales (scutes) that other birds have. Another shared characteristic is long wings with short, stout humerus bones. The evolution of these wing characteristics has provided the hummingbird with ideal wings for hovering.Mayr, Gerald (2003): Phylogeny of early tertiary swifts and hummingbirds (Aves: Apodiformes).

Caprimulgiformes
Nightjars are medium-sized nocturnal or crepuscular birds in the family Caprimulgidae and order Caprimulgiformes, characterised by long wings, short legs, and very short bills. They are sometimes called goatsuckers, due to the ancient folk tale that they sucked the milk from goats (the Latin for goatsucker is ''caprimulgus''), or bugeaters, their primary source of food being insects. Some New World species are called nighthawks. The English word "nightjar" originally referred to the European nightjar. Nightjars are found all around the world, with the exception of Antarctica and certain island groups such as the Seychelles. They can be found in a variety of habitats, most commonly the open country with some vegetation. They usually nest on the ground, with a habit of resting and roosting on roads. The subfamilies of nightjars have similar characteristics, including small feet, of little use for walking, and long, pointed wings. Typical nightjars, though, have rictal bristle ...

Cuculiformes
Cuckoos are birds in the Cuculidae family, the sole taxon in the order Cuculiformes . The cuckoo family includes the common or European cuckoo, roadrunners, koels, malkohas, couas, coucals and anis. The coucals and anis are sometimes separated as distinct families, the Centropodidae and Crotophagidae respectively. The cuckoo order Cuculiformes is one of three that make up the Otidimorphae, the other two being the turacos and the bustards. The family Cuculidae contains 150 species which are divided into 33 genera. The cuckoos are generally medium-sized slender birds. Most species live in trees, though a sizeable minority are ground-dwelling. The family has a cosmopolitan distribution; the majority of species are tropical. Some species are migratory. The cuckoos feed on insects, insect larvae and a variety of other animals, as well as fruit. Some species are brood parasites, laying their eggs in the nests of other species and giving rise to the metaphor ''cuckoo's egg'', b ...

Columbiformes
Columbidae () is a bird family consisting of doves and pigeons. It is the only family in the order Columbiformes. These are stout-bodied birds with short necks and short slender bills that in some species feature fleshy ceres. They primarily feed on seeds, fruits, and plants. The family occurs worldwide, but the greatest variety is in the Indomalayan and Australasian realms. The family contains 344 species divided into 50 genera. Thirteen of the species are extinct. In English, the smaller species tend to be called "doves" and the larger ones "pigeons". However, the distinction is not consistent, and does not exist in most other languages. Historically, the common names for these birds involve a great deal of variation between the terms. The bird most commonly referred to as just "pigeon" is the domestic pigeon, which is common in many cities as the feral pigeon. Doves and pigeons build relatively flimsy nests, often using sticks and other debris, which may be placed on bran ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Charadriiformes
Charadriiformes (, from ''Charadrius'', the type genus of family Charadriidae) is a diverse order of small to medium-large birds. It includes about 390 species and has members in all parts of the world. Most charadriiform birds live near water and eat invertebrates or other small animals; however, some are pelagic (seabirds), others frequent deserts, and a few are found in dense forest. Members of this group can also collectively be referred to as shorebirds. Taxonomy, systematics and evolution The order was formerly divided into three suborders: * The waders (or "Charadrii"): typical shorebirds, most of which feed by probing in the mud or picking items off the surface in both coastal and freshwater environments. * The gulls and their allies (or " Lari"): these are generally larger species which take fish from the sea. Several gulls and skuas will also take food items from beaches, or rob smaller species, and some have become adapted to inland environments. * The auks (or "Alcae" ...
