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. Greater North America 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.
Continental 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, African slaves, immigrants from Europe, Asia, and descendants of these respective groups.

The Canada jay (Perisoreus canadensis), also known as the gray jay, grey jay, camp robber, or whisky jack, is a passerine bird of the family Corvidae. It is found in boreal forests of North America north to the tree line, and in the Rocky Mountains subalpine zone south to New Mexico and Arizona. A fairly large songbird, the Canada jay has pale grey underparts, darker grey upperparts, and a grey-white head with a darker grey nape. It is one of three members of the genus Perisoreus, a genus more closely related to the magpie genus Cyanopica than to other birds known as jays. The Canada jay itself has nine recognized subspecies.
Canada jays live year-round on permanent territories in coniferous forests, surviving in winter months on food cached throughout their territory in warmer periods. The birds form monogamous mating pairs, with pairs accompanied on their territories by a third juvenile from the previous season. Canada jays adapt to human activity in their territories and are known to approach humans for food, inspiring a list of colloquial names including "lumberjack", "camp robber", and "venison-hawk". The International Union for Conservation of Nature (IUCN) considers the Canada jay a least-concern species, but populations in southern ranges may be affected adversely by global warming.

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".

The foundation line of breeding stock was first imported from Italy into Canada in 1979, and into the United States in the early 1980s. Piedmontese cattle are distinguished by a unique, naturally occurring gene identified as the myostatin allele mutation, or inactive myostatin gene. Myostatin prohibits muscle growth whereas an inactive gene has the opposite effect. Purebred Piedmontese are homozygous, (2 copy), which means they have two identical alleles present for this unique gene. Research indicates the presence of the myostatin allele mutation produces morphological characteristics unique to the breed, such as double-muscling, beef tenderness, reduced fat content and high yield. According to the North American Piedmontese Association (NAPA), they are the first breed registry to base animal registration requirements on the presence of this specific gene which can be easily verified by DNA testing.
