United States
–
Forty-eight of the fifty states and the federal district are contiguous and located in North America between Canada and Mexico. The state of Alaska is in the northwest corner of North America, bordered by Canada to the east, the state of Hawaii is an archipelago in the mid-Pacific Ocean. The U. S. territories are scattered about the Pacific Ocean, the geography, climate and wildlife of the country are extremely diverse. At 3.8 million square miles and with over 324 million people, the United States is the worlds third- or fourth-largest country by area, third-largest by land area. It is one of the worlds most ethnically diverse and multicultural nations, paleo-Indians migrated from Asia to the North American mainland at least 15,000 years ago. European colonization began in the 16th century, the United States emerged from 13 British colonies along the East Coast. Numerous disputes between Great Britain and the following the Seven Years War led to the American Revolution. On July 4,1776, during the course of the American Revolutionary War, the war ended in 1783 with recognition of the independence of the United States by Great Britain, representing the first successful war of independence against a European power. The current constitution was adopted in 1788, after the Articles of Confederation, the first ten amendments, collectively named the Bill of Rights, were ratified in 1791 and designed to guarantee many fundamental civil liberties. During the second half of the 19th century, the American Civil War led to the end of slavery in the country. By the end of century, the United States extended into the Pacific Ocean. The Spanish–American War and World War I confirmed the status as a global military power. The end of the Cold War and the dissolution of the Soviet Union in 1991 left the United States as the sole superpower. The U. S. is a member of the United Nations, World Bank, International Monetary Fund, Organization of American States. The United States is a developed country, with the worlds largest economy by nominal GDP. It ranks highly in several measures of performance, including average wage, human development, per capita GDP. While the U. S. economy is considered post-industrial, characterized by the dominance of services and knowledge economy, the United States is a prominent political and cultural force internationally, and a leader in scientific research and technological innovations. In 1507, the German cartographer Martin Waldseemüller produced a map on which he named the lands of the Western Hemisphere America after the Italian explorer and cartographer Amerigo Vespucci

Delaware
–
Delaware is a state located in the Mid-Atlantic and/or Northeastern regions of the United States. It is bordered to the south and west by Maryland, to the northeast by New Jersey, the state takes its name from Thomas West, 3rd Baron De La Warr, an English nobleman and Virginias first colonial governor. Delaware occupies the portion of the Delmarva Peninsula and is the second smallest, the sixth least populous. Delaware is divided into three counties, the lowest number of counties of any state, from north to south, the three counties are New Castle, Kent, and Sussex. While the southern two counties have historically been agricultural, New Castle County has been more industrialized. Before its coastline was explored by Europeans in the 16th century, Delaware was inhabited by groups of Native Americans, including the Lenape in the north. It was initially colonized by Dutch traders at Zwaanendael, near the present town of Lewes, Delaware was one of the 13 colonies participating in the American Revolution. On December 7,1787, Delaware became the first state to ratify the Constitution of the United States, the Delaware Indians, a name used by Europeans for Lenape people indigenous to the Delaware Valley, also derive their name from the same source. The surname de La Warr comes from Sussex and is of Anglo-Norman origin and it came probably from a Norman lieu-dit La Guerre. This toponymic could derive from the Latin word ager, from the Breton gwern or from the Late Latin varectum, the toponyms Gara, Gare, Gaire also appear in old texts cited by Lucien Musset, where the word gara means gore. It could also be linked with a patronymic from the Old Norse verr, Delaware is 96 miles long and ranges from 9 miles to 35 miles across, totaling 1,954 square miles, making it the second-smallest state in the United States after Rhode Island. Delaware is bounded to the north by Pennsylvania, to the east by the Delaware River, Delaware Bay, New Jersey and the Atlantic Ocean, small portions of Delaware are also situated on the eastern side of the Delaware River sharing land boundaries with New Jersey. The state of Delaware, together with the Eastern Shore counties of Maryland, the definition of the northern boundary of the state is unusual. Most of the boundary between Delaware and Pennsylvania was originally defined by an arc extending 12 miles from the cupola of the courthouse in the city of New Castle and this boundary is often referred to as the Twelve-Mile Circle. This is the only nominally circular state boundary in the United States, to the west, a portion of the arc extends past the easternmost edge of Maryland. The remaining western border runs slightly east of due south from its intersection with the arc, the Wedge of land between the northwest part of the arc and the Maryland border was claimed by both Delaware and Pennsylvania until 1921, when Delawares claim was confirmed. Delaware is on a plain, with the lowest mean elevation of any state in the nation. Its highest elevation, located at Ebright Azimuth, near Concord High School, the northernmost part of the state is part of the Piedmont Plateau with hills and rolling surfaces

Sussex County, Delaware
–
Sussex County is a county located in the southern part of the U. S. state of Delaware, on the Delmarva Peninsula. As of the 2010 census, the population was 197,145, the first European settlement in the state of Delaware was founded by the Dutch in 1631 near the present-day town of Lewes on the Atlantic Coast. However, Sussex County was not organized until 1683 under English colonial rule, Sussex County is included in the Salisbury, MD-DE Metropolitan Statistical Area which encompasses much of central Delmarva. Archaeologists estimate that the first inhabitants of Sussex County, the southernmost county in Delaware, various indigenous cultures occupied the area, especially along the river and the coast, often having seasonal fishing villages. Historic Native Americans in Sussex County were members of Algonquian-speaking tribes, the people settled along the numerous bodies of water in the area where they were able to harvest fish, oysters, and other shellfish in the fall and winter. In the warmer months the women planted and cultivated crops, the men hunted deer and other small mammals, as larger game was not present in the area. There is no agreement on which European group was the first to settle in Sussex County, on an expedition for the Dutch West India Company, Henry Hudson recorded discovery in 1609 of what was later named the Delaware River. Attempting to following him, Samuel Argall, an English explorer, was blown off course in 1610 and landed in a bay which he named after the Governor of Virginia, Thomas West. In the first half of 1613, Cornelius Jacobsen Mey, a Dutch navigator, later it was found that what May had named Henlopen was Fenwick Island, protruding into the Atlantic Ocean. The name of the cape was moved to its present location just east of Lewes, Sussex County was the site of the first European settlement in Delaware, a Dutch trading post named Zwaanendael at the present site of Lewes. On June 3,1631, Dutch captain David Pietersen de Vries landed along the shores of the Delaware to establish a colony in the mid-Atlantic of the New World. The colony lasted only until 1632, when De Vries left, upon returning to Zwaanendael that December, he found the Indian tribes had killed his men and burned the colony. The Dutch set about settling the area once again, although the Dutch and Swedes returned to resettle the Delaware River region as early as 1638, much of the Delaware Bay area south of what is today the city of Newcastle was not settled until 1662. At that time, the city of Amsterdam made a grant of land at the Hoernkills to a party of Mennonites. A total of 35 men were to be included in the settlement, led by a Pieter Cornelisz Plockhoy of Zierikzee, and funded by a sizable loan from the city to get them established. This settlement, established in 1663, was organized in part by the Dutch to respond to threats from the English colony of Maryland to the west beginning to assert rights over the area. The English wrested control of New Netherland from the Dutch in 1664 and they destroyed the Mennonite settlement that same year, settlement in the area after the English ejected the Dutch was slow. Lord Baltimore encouraged Marylanders to move east to settle the area, but the land was far removed from other, more established settlements and did not appeal to many new settlers

Wetland
–
A wetland is a land area that is saturated with water, either permanently or seasonally, such that it takes on the characteristics of a distinct ecosystem. The primary factor that distinguishes wetlands from other forms or water bodies is the characteristic vegetation of aquatic plants. Wetlands play a number of roles in the environment, principally water purification, flood control, carbon sink, Wetlands are also considered the most biologically diverse of all ecosystems, serving as home to a wide range of plant and animal life. Wetlands occur naturally on every continent except Antarctica, the largest including the Amazon River basin, the West Siberian Plain, the water found in wetlands can be freshwater, brackish, or saltwater. The main wetland types include swamps, marshes, bogs, and fens, and sub-types include mangrove, carr, pocosin, the UN Millennium Ecosystem Assessment determined that environmental degradation is more prominent within wetland systems than any other ecosystem on Earth. International conservation efforts are being used in conjunction with the development of rapid assessment tools to people about wetland issues. Constructed wetlands can be used to treat municipal and industrial wastewater as well as stormwater runoff and they may also play a role in water-sensitive urban design. A patch of land that develops pools of water after a storm would not be considered a wetland. Wetlands have unique characteristics, they are distinguished from other water bodies or landforms based on their water level. Specifically, wetlands are characterized as having a table that stands at or near the land surface for a long enough period each year to support aquatic plants. A more concise definition is a community composed of hydric soil, Wetlands have also been described as ecotones, providing a transition between dry land and water bodies. In environmental decision-making, there are subsets of definitions that are agreed upon to make regulatory and policy decisions. A wetland is an ecosystem that arises when inundation by water produces soils dominated by anaerobic processes, There are four main kinds of wetlands – marsh, swamp, bog and fen. Some experts also recognize wet meadows and aquatic ecosystems as additional wetland types, the largest wetlands in the world include the swamp forests of the Amazon and the peatlands of Siberia. Under the Ramsar international wetland conservation treaty, wetlands are defined as follows, Article 2.1, may incorporate riparian and coastal zones adjacent to the wetlands, and islands or bodies of marine water deeper than six metres at low tide lying within the wetlands. Although the general definition given above applies around the world, each county, Wetlands generally include swamps, marshes, bogs and similar areas. This definition has been used in the enforcement of the Clean Water Act, some US states, such as Massachusetts and New York, have separate definitions that may differ from the federal governments. It is not uncommon for a wetland to be dry for long portions of the growing season, the most important factor producing wetlands is flooding

Bird
–
Birds, a subgroup of Reptiles, are the last living examples of Dinosaurs. Birds live worldwide and range in size from the 5 cm bee hummingbird to the 2.75 m ostrich. They rank as the class of tetrapods with the most living species, at ten thousand. Birds are the closest living relatives of crocodilians, the fossil record indicates that birds evolved from feathered ancestors within the theropod group of saurischian dinosaurs. True birds first appeared during the Cretaceous period, around 100 million years ago, Birds, especially those in the southern continents, survived this event and then migrated to other parts of the world while diversifying during periods of global cooling. Primitive bird-like dinosaurs that lie outside class Aves proper, in the broader group Avialae, have been found dating back to the mid-Jurassic period, around 170 million years ago. Birds have wings which are more or less developed depending on the 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 evolved for swimming. Many species annually migrate great distances, Birds are social, communicating with visual signals, calls, and bird songs, and participating in such social behaviours as cooperative breeding and hunting, flocking, and mobbing of predators. The vast majority of species are socially monogamous, usually for one breeding season at a time, sometimes for years. Other species have breeding systems that are polygynous or, rarely, Birds produce offspring by laying eggs which are fertilised through sexual reproduction. They are usually laid in a nest and incubated by the parents, most birds have an extended period of parental care after hatching. Some birds, such as hens, lay eggs even when not fertilised, songbirds, parrots, and other species are popular as pets. Guano is harvested for use as a fertiliser, Birds prominently figure throughout human culture. About 120–130 species have become extinct due to human activity since the 17th century, human activity threatens about 1,200 bird species with extinction, though efforts are underway to protect them. Recreational birdwatching is an important part of the ecotourism industry, the first classification of birds was developed by Francis Willughby and John Ray in their 1676 volume Ornithologiae. Carl Linnaeus modified that work in 1758 to devise the taxonomic classification system currently in use, Birds are categorised as the biological class Aves in Linnaean taxonomy. Phylogenetic taxonomy places Aves in the dinosaur clade Theropoda, Aves and a sister group, the clade Crocodilia, contain the only living representatives of the reptile clade Archosauria

Great blue heron
–
It is a rare vagrant to coastal Spain, the Azores, and areas of far southern Europe. An all-white population found only in the Caribbean and Florida was once treated as a separate species, the great blue heron was one of the many species originally described by Carl Linnaeus in his 18th-century work, Systema Naturae. The scientific name comes from Latin ardea, and Ancient Greek erodios and it forms a superspecies with this and also with the cocoi heron from South America, which differs in having more extensive black on the head, and a white breast and neck. It has head-to-tail length of 91–137 cm, a wingspan of 167–201 cm, a height of 115–138 cm, in British Columbia, adult males averaged 2.48 kg and adult females 2.11 kg. The feathers on the neck are long and plume-like, it also has plumes on the lower back at the start of the breeding season. The bill is yellowish, becoming orange briefly at the start of the breeding season. Immature birds are duller in color, with a dull blackish-gray crown, and the pattern is only weakly defined, they have no plumes. Among standard measurements, the chord is 43–49.2 cm, the tail is 15. 2–19.5 cm, the culmen is 12. 3–15.2 cm. The herons stride is around 22 cm, almost in a straight line, two of the three front toes are generally closer together. In a track, the front toes, as well as the back, the subspecies differ only slightly in size and plumage tone, with the exception of subspecies A. h. occidentalis, which also has a distinct white morph, known as the great white heron. It is found only in south Florida and some parts of the Caribbean, the great white heron differs from other great blues in bill morphology, head plume length, and in having a total lack of pigment in its plumage. It averages somewhat larger than the sympatric race A. h. wardi and may be the largest race in the species. In a survey of A. h. occidentalis in Florida, males were found to average 3.02 kg and females average 2.57 kg and this is mainly found near salt water, and was long thought to be a separate species. Birds intermediate between the normal morph and the white morph are known as Würdemanns heron, these birds resemble a normal great blue with a white head. The theory that great white herons may be a species from great blue heron has again been given some support by David Sibley. The great white heron could be confused with great egret, but is larger, the reddish egret and little blue heron could be mistaken for the great blue heron, but are much smaller, and lack white on the head and yellow in the bill. In the southern reaches of its range, the great blue sometimes overlaps in range with the closely related, the cocoi is distinguished by a striking white neck and solid black crown, but the duller juveniles are more easily confused. More superficially similar is the slightly smaller grey heron, which may sometimes vagrate to the coasts of North America
