The North America Portal

North America is a continent in the Northern and Western Hemispheres. North America is bordered to the north by the Arctic Ocean, to the east by the Atlantic Ocean, to the southeast by South America and the Caribbean Sea, and to the west and south by the Pacific Ocean. The region includes the Bahamas, Bermuda, Canada, the Caribbean, Central America, Clipperton Island, Greenland, Mexico, Saint Pierre and Miquelon, Turks and Caicos Islands, and the United States.

North America covers an area of about 24,709,000 square kilometers (9,540,000 square miles), representing approximately 16.5% of the Earth's land area and 4.8% of its total surface area. It is the third-largest continent by size after Asia and Africa, and the fourth-largest continent by population after Asia, Africa, and Europe. , North America's population was estimated as over 592 million people in 23 independent states, or about 7.5% of the world's population. In human geography, the terms "North America" and "North American" sometimes refer to just Canada, the United States, Mexico, and Greenland.

It is unknown with certainty how and when first human populations first reached North America. People were known to live in the Americas at least 20,000 years ago, but various evidence points to possibly earlier dates. The Paleo-Indian period in North America followed the Last Glacial Period, and lasted until about 10,000 years ago when the Archaic period began. The classic stage followed the Archaic period, and lasted from approximately the 6th to 13th centuries. Beginning in 1000 AD, the Norse were the first Europeans to begin exploring and ultimately colonizing areas of North America.

In 1492, the exploratory voyages of Christopher Columbus led to a transatlantic exchange, including migrations of European settlers during the Age of Discovery and the early modern period. Present-day cultural and ethnic patterns reflect interactions between European colonists, indigenous peoples, enslaved Africans, immigrants from Europe, Asia, and descendants of these respective groups.

Cardellina rubra melanauris
Sinaloa, Mexico

The red warbler (Cardellina rubra) is a small passerine bird of the New World warbler family Parulidae endemic to the highlands of Mexico, north of the Isthmus of Tehuantepec. It is closely related to, and forms a superspecies with, the pink-headed warbler of southern Mexico and Guatemala. There are three subspecies, found in disjunct populations, which differ in the color of their ear patch and in the brightness and tone of their body plumage. The adult is bright red, with a white or gray ear patch, depending on the subspecies; young birds are pinkish-brown, with a whitish ear patch and two pale wingbars.

Breeding typically occurs between February and May. The female lays three or four eggs in a domed nest, which she builds on the ground. Though she alone incubates the eggs, both sexes feed the young and remove fecal sacs from the nest. The young fledge within 10–11 days of hatching. The red warbler is an insectivore, gleaning primarily in understory shrubs. Although this bird is considered to be a least-concern species according to the International Union for Conservation of Nature (IUCN), its numbers are thought to be declining due to habitat destruction.

A daguerreotype of the United States Capitol in 1846, with the original green copper dome as designed by Charles Bulfinch. Over time, extensions to both the north and south wings, made to accommodate the addition of new states to the Union, made the dome aesthetically displeasing, and as a result, it was replaced by a white cast iron dome which was completed in 1866.

Adams circa 1870

Daniel Lucius "Doc" Adams (November 1, 1814 – January 3, 1899) was an American baseball player and executive who is regarded by historians as an important figure in the sport's early years. For most of his career he was a member of the New York Knickerbockers. He first played for the New York Base Ball Club in 1840 and started his Knickerbockers career five years later, continuing to play for the club into his forties and to take part in inter-squad practice games and matches against opposing teams. Researchers have called Adams the creator of the shortstop position, which he used to field short throws from outfielders. In addition to his playing career, Adams manufactured baseballs and oversaw bat production; he also occasionally acted as an umpire.

From 1847 to 1861, the Knickerbockers selected Adams as their president six times, and as a vice president, treasurer, or director in six other years. As president of the club, Adams was an advocate of rule changes in baseball that resulted in nine-man teams and nine-inning games. When the National Association of Base Ball Players (NABBP) was formed in 1858, he led the rules and regulations committee of the new organization. In his role, Adams ruled that the fields' bases should be 90 feet (27 m) apart, the modern distance, and supported the elimination of the "bound rule", which allowed for balls caught after one bounce to be recorded as outs. He resigned from his positions with the Knickerbockers and NABBP in 1862. Adams' contributions in creating baseball's rules went largely unrecognized for decades after his 1899 death, but in 1980 a letter about him appeared in The New York Times; by 1993, researcher John Thorn had written about Adams' role. Other historians have given him credit for helping to develop the sport, and Thorn has called Adams "first among the Fathers of Baseball". (Full article...)
