Ramsar Convention
The Ramsar Convention on Wetlands of International Importance Especially as Waterfowl Habitat is an international treaty for the conservation and sustainable use of Ramsar sites (wetlands). It is also known as the Convention on Wetlands. It is named after the city of Ramsar in Iran, where the convention was signed in 1971. Every three years, representatives of the contracting parties meet as the Conference of the Contracting Parties (COP), the policy-making organ of the convention which adopts decisions (resolutions and recommendations) to administer the work of the convention and improve the way in which the parties are able to implement its objectives. COP12 was held in Punta del Este, Uruguay, in 2015. COP13 was held in Dubai, United Arab Emirates, in October 2018. List of wetlands of international importance The list of wetlands of international importance included 2,331 Ramsar sites in May 2018 covering over .

Northern Pintail
The pintail or northern pintail (''Anas acuta'') is a duck species with wide geographic distribution that breeds in the northern areas of Europe and across the Palearctic and North America. It is migratory and winters south of its breeding range to the equator. Unusually for a bird with such a large range, it has no geographical subspecies if the possibly conspecific duck Eaton's pintail is considered to be a separate species. This is a large duck, and the male's long central tail feathers give rise to the species' English and scientific names. Both sexes have blue-grey bills and grey legs and feet. The drake is more striking, having a thin white stripe running from the back of its chocolate-coloured head down its neck to its mostly white undercarriage. The drake also has attractive grey, brown, and black patterning on its back and sides. The hen's plumage is more subtle and subdued, with drab brown feathers similar to those of other female dabbling ducks. Hens make a coarse ...

Lesser Yellow-headed Vulture
The lesser yellow-headed vulture (''Cathartes burrovianus'') also known as the savannah vulture, is a species of bird in the New World vulture family Cathartidae. It was considered to be the same species as the greater yellow-headed vulture until they were split in 1964. It is found in Mexico, Central America, and South America in seasonally wet or flooded lowland grassland, swamps, and heavily degraded former forest. It is a large bird, with a wingspan of . The body plumage is black, and the head and neck, which are featherless, are pale orange with red or blue areas. It lacks a syrinx, so therefore its vocalizations are limited to grunts or low hisses. The lesser yellow-headed vulture feeds on carrion and locates carcasses by sight and by smell, an ability which is rare in birds. It is dependent on larger vultures, such as the king vulture, to open the hides of larger animal carcasses as its bill is not strong enough to do this. Like other New World vultures, the lesser yellow ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Peregrine Falcon
The peregrine falcon (''Falco peregrinus''), also known as the peregrine, and historically as the duck hawk in North America, is a Cosmopolitan distribution, cosmopolitan bird of prey (Bird of prey, raptor) in the family (biology), family Falconidae. A large, Corvus (genus), crow-sized falcon, it has a blue-grey back, barred white underparts, and a black head. The peregrine is renowned for its speed, reaching over during its characteristic hunting stoop (high-speed dive), making it the fastest bird in the world, as well as the Fastest animals, fastest member of the animal kingdom. According to a ''National Geographic (U.S. TV channel), National Geographic'' TV program, the highest measured speed of a peregrine falcon is . As is typical for avivore, bird-eating raptors, peregrine falcons are Sexual dimorphism, sexually dimorphic, with females being considerably larger than males. The peregrine's breeding range includes land regions from the Arctic tundra to the tropics. It can b ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Eastern Kingbird
The eastern kingbird (''Tyrannus tyrannus'') is a large tyrant flycatcher native to the Americas. The bird is predominantly dark gray with white underbelly and pointed wings. Eastern kingbirds are conspicuous and are commonly found in open areas with scattered trees and bushes, where they perch while foraging for insects. The Eastern kingbird is migratory, with its breeding range spread across North America and its wintering range in Central and South America. Taxonomy The eastern kingbird was Species description, described by the Swedish naturalist Carl Linnaeus in 1758 in the 10th edition of Systema Naturae, tenth edition of his ''Systema Naturae'' under the binomial nomenclature, binomial name of ''Lanius tyrannus''. The present genus ''Tyrannus'' was introduced in 1799 by the French naturalist Bernard Germain de Lacépède with the eastern kingbird as the type species. The species is monotypic; no subspecies are recognised. Description Adults are grey-black on the upperparts ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Scissor-tailed Flycatcher
The scissor-tailed flycatcher (''Tyrannus forficatus''), also known as the Texas bird-of-paradise and swallow-tailed flycatcher, is a long-tailed bird of the genus ''Tyrannus'', whose members are collectively referred to as kingbirds. The kingbirds are a group of large insectivorous (insect-eating) birds in the tyrant flycatcher (Tyrannidae) family. The scissor-tailed flycatcher is found in North and Central America. Latin name and etymology Its former Latin name was ''Muscivora forficata''. The former genus name ''Muscivora'' derives from the Latin words for 'fly' () and 'to devour' (), while the species name ''forficata'' derives from the Latin word for 'scissors' (). The scissortail is now considered to be a member of the ''Tyrannus'', or 'tyrant-like' genus. This genus earned its name because several of its species are extremely aggressive on their breeding territories, where they will attack larger birds such as crows, hawks and owls.

Great Black Hawk
The great black hawk (''Buteogallus urubitinga'') is a bird of prey in the family Accipitridae, which also includes the eagles, hawks, and Old World vultures. Taxonomy The great black hawk was Species description, formally described in 1788 by the German naturalist Johann Friedrich Gmelin in his revised and expanded edition of Carl Linnaeus's ''Systema Naturae''. He placed it with the eagles, hawks and relatives in the genus ''Falco (bird), Falco'' and coined the binomial nomenclature, binomial name ''Falco urubitinga''. Gmelin's description was ultimately based on the "urubitinga" that had been described in 1648 by the German naturalist Georg Marcgrave in his ''Historia Naturalis Brasiliae''. The great black hawk is now one of nine species placed in the genus ''Buteogallus'' was introduced in 1830 by the French naturalist René Lesson. The name genus is a portmanteau of ''Buteo'', a genus introduced in 1779 by Bernard Germain de Lacépède for the buzzards and the genus ''Gallus ...

White-winged Dove
The white-winged dove (''Zenaida asiatica'') is a dove whose native range extends from the Southwestern United States through Mexico, Central America, and the Caribbean. They are large for doves, and can be distinguished from similar doves by the distinctive white edge on their wings. They have a blue eyering, and red eyes. The plumage is brownish-gray to gray. Juveniles are duller in color, and have brown eyes. The call is likened to English phrase "who cooks for you". There are three subspecies. It was first described by George Edwards in 1743, and given its binomial name by Linnaeus in 1756. It was moved into the genus ''Zenaida'' in 1838. They inhabit a variety of environments, including desert, scrub, and urban. Their diet consists mostly of grains, but will also include pollen and nectar, especially from the saguaro cactus, which is a vital source of water. The expansion of humans has greatly affected the white-winged dove. Prior to human presence, their range closely ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Least Bittern
The least bittern (''Ixobrychus exilis'') is a small heron, the smallest member of the family Ardeidae found in the Americas. Taxonomy The least bittern was formally described in 1789 by the German naturalist Johann Friedrich Gmelin in his revised and expanded edition of Carl Linnaeus's ''Systema Naturae''. He placed it with the herons, cranes, storks and bitterns in the genus '' Ardea'' and coined the binomial name ''Ardea exilis''. Gmelin based his description on the "minute bittern" from Jamaica that had been included by the English ornithologist John Latham in his multi-volume work ''A General Synopsis of Birds''. Latham did not specify how he had obtained the specimen. The least bittern is now one of ten species placed in the genus ''Ixobrychus'' that was introduced in 1828 by the Swedish naturalist Gustaf Johan Billberg. The genus name combines the Ancient Greek ''ixias'', a reed-like plant and ''brukhomai'', to bellow. The specific epithet ''exilis'' is Latin meaning "l ...
