Slender-billed Gull
The slender-billed gull (''Chroicocephalus genei'') is a mid-sized gull which breeds very locally around the Mediterranean and the north of the western Indian Ocean (e.g. Pakistan) on islands and coastal lagoons. Most of the population is somewhat migratory, wintering further south to as far as North Africa and India. A few birds have wandered to western Europe. A vagrant individual was reportedly seen on Antigua, April 24, 1976 ( AOU, 2000). The genus name '' Chroicocephalus'' is from Ancient Greek ''khroizo'', "to colour", and ''kephale'', "head". The specific ''genei'' commemorates Italian naturalist Giuseppe Gené. Description This species is long with a wingspan. It is therefore slightly larger than the black-headed gull, which it resembles, although it does not have a black hood in summer. It has a pale grey body, white head and breast and black tips to the primary wing feathers. The head and dark red bill have an elongated tapering appearance, and this bird also appea ...

Bahrain
Bahrain, officially the Kingdom of Bahrain, is an island country in West Asia. Situated on the Persian Gulf, it comprises a small archipelago of 50 natural islands and an additional 33 artificial islands, centered on Bahrain Island, which makes up around 83 percent of the country's landmass. Bahrain is situated between Qatar and the northeastern coast of Saudi Arabia, to which it is connected by the King Fahd Causeway. The population of Bahrain is 1,501,635 as of 14 May 2023, of whom 712,362 (47.44%) are Bahraini nationals and 789,273 are expatriates spanning 2,000 ethnicities (52.56% of the country's population of 1,501,635). Bahrain spans some , and is the List of countries and dependencies by area, third-smallest nation in Asia after the Maldives and Singapore. The capital and largest city is Manama. According to archeologist Geoffrey Bibby, Bahrain is the site of the ancient Dilmun civilization. though locally the islands were controlled by the Shia Jarwanids, Jarwanid dyn ...

Giuseppe Gené
Carlo Giuseppe Gené (7 December 1800 – 14 July 1847) was an Italian natural history, naturalist and author. Gené was born at Turbigo in Lombardy and studied at the University of Pavia. He published a number of papers on natural history, particularly entomology. In 1828 he became an assistant lecturer in natural history at the university, and in the following year he traveled to Hungary, returning with a collection of insect specimens. Between 1833 and 1838 he made four trips to Sardinia collecting insects. In 1830 Gené succeeded Franco Andrea Bonelli as professor of zoology and director of the Royal Zoological Museum at Turin. Most of his insect collection is in the Turin Museum of Natural History. Duplicates are in Museo Civico di Storia Naturale di Milano and in Natural History Museum of the University of Pisa, Museo di storia naturale dell'Università di Pisa. The slender-billed gull (''Larus genei'') was named after him. Works *A work on apiculture (1835)''De quibusdam ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Birds Of West Asia
Birds are a group of warm-blooded vertebrates constituting the class Aves (), characterised by feathers, toothless beaked jaws, the laying of hard-shelled eggs, a high metabolic rate, a four-chambered heart, and a strong yet lightweight 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 orders. More than half are passerine or "perching" birds. Birds have wings whose development varies according to species; the only known groups without wings are the extinct moa and elephant birds. Wings, which are modified forelimbs, gave birds the ability to fly, although further evolution has led to the loss of flight in some birds, including ratites, penguins, and diverse endemic island species. The digestive and respiratory systems of birds are also uniquely adapted for flight. Some bird species of aquatic environments, particularly seabirds and some waterbirds, have furth ...

Birds Of Europe
More than 900 species of birds have been observed in Europe. The avifauna of Europe is broadly similar to that of Asia north of the Himalayas and North Africa, both of which also belong to the Palearctic realm. There are also many groups shared with North America. On the other hand, many groups characteristic of the Afrotropical and Indomalayan realms are entirely absent from Europe, including jacanas, darters, trogons, hornbills, honeyguides, barbets (families Lybiidae in Africa and Megalaimidae in Asia), parrots, pittas, cuckooshrikes, broadbills (families Calyptomenidae and Eurylaimidae), drongos, monarch flycatchers, white-eyes, and estrildid finches (although parrots and estrildid finches have been introduced to Europe by humans). Two species that occurred in the European region until recently (post 1800) — the great auk and the Canary Islands oystercatcher — are now globally extinct, while one additional species — the slender-billed curlew — may also ...

Chroicocephalus
''Chroicocephalus'' is a genus of medium to relatively small gulls which were included in the genus ''Larus'' until genetic evidence published in 2005 showed that ''Larus'' as then constituted was paraphyly, paraphyletic. Ten species are currently accepted. The genus name ''Chroicocephalus'' is from Ancient Greek ''khroizo'', "to colour", and ''kephale'', "head". Taxonomy The species now placed in this genus were formerly assigned to the genus ''Larus''. A molecular phylogenetic study published in 2005 found that ''Larus'', as then constituted, was paraphyletic. In the resulting rearrangement to create monophyletic genera, the genus ''Chroicocephalus'' with resurrected to contain a clade of species, all of which have black heads. The genus ''Chroicocephalus'' had been introduced in 1836 by the English naturalist Thomas Campbell Eyton. Although he listed two species in the new genus, he did not specify a type species, type. In 1840 George Robert Gray, George Gray designated the typ ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
AEWA
The Agreement on the Conservation of African-Eurasian Migratory Waterbirds, or African-Eurasian Waterbird Agreement (AEWA), is an independent international treaty developed under the auspices of the United Nations Environment Programme's Convention on Migratory Species. Background The Agreement on the Conservation of African-Eurasian Migratory Waterbirds was drafted on 19 June 1995 in The Hague, Netherlands, in order to coordinate efforts to conserve bird species migrating between European and African nations. Description The AEWA is an independent treaty under the auspices of the Convention on Migratory Species, of the United Nations Environment Programme. The agreement focuses on bird species that depend on wetlands for at least part of their lifecycle and cross international borders in their migration patterns. As of 2023 it covered 255 species. As of July 2023, its scope covered territories in 119 Range States stretching from the Arctic to South Africa, encompassing the ...

Colony (biology)
In biology, a colony is composed of two or more Biological specificity#Conspecific, conspecific individuals living in close association with, or connected to, one another. This association is usually for mutual benefit such as stronger defense or the ability to attack bigger prey. Colonies can form in various shapes and ways depending on the organism involved. For instance, the bacterial colony is a cluster of identical cells (clones). These colonies often form and grow on the surface of (or within) a solid medium, usually derived from a single parent cell. Colonies, in the context of development, may be composed of two or more unitary (or solitary) organisms or be Modularity, modular organisms. Unitary organisms have determinate development (set life stages) from zygote to adult form and individuals or groups of individuals (colonies) are visually distinct. Modular organisms have indeterminate growth forms (life stages not set) through repeated iteration of genetically identi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Predation
Predation is a biological interaction in which one organism, the predator, kills and eats another organism, its prey. It is one of a family of common List of feeding behaviours, feeding behaviours that includes parasitism and micropredation (which usually do not kill the Host (biology), host) and parasitoidism (which always does, eventually). It is distinct from Scavenger, scavenging on dead prey, though many predators also scavenge; it overlaps with Herbivore, herbivory, as Seed predation, seed predators and destructive frugivores are predators. Predation behavior varies significantly depending on the organism. Many predators, especially carnivores, have evolved distinct hunting strategy, hunting strategies. Pursuit predation involves the active search for and pursuit of prey, whilst ambush predation, ambush predators instead wait for prey to present an opportunity for capture, and often use stealth or aggressive mimicry. Other predators are opportunism, opportunistic or om ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mediterranean Sea
The Mediterranean Sea ( ) is a sea connected to the Atlantic Ocean, surrounded by the Mediterranean basin and almost completely enclosed by land: on the east by the Levant in West Asia, on the north by Anatolia in West Asia and Southern Europe, on the south by North Africa, and on the west almost by the Morocco–Spain border. The Mediterranean Sea covers an area of about , representing 0.7% of the global ocean surface, but its connection to the Atlantic via the Strait of Gibraltar—the narrow strait that connects the Atlantic Ocean to the Mediterranean Sea and separates the Iberian Peninsula in Europe from Morocco in Africa—is only wide. Geological evidence indicates that around 5.9 million years ago, the Mediterranean was cut off from the Atlantic and was partly or completely desiccation, desiccated over a period of some 600,000 years during the Messinian salinity crisis before being refilled by the Zanclean flood about 5.3 million years ago. The sea was an important ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
