Context paragraphs:
St. George and the Dragon (ballad): "St. George and the Dragon," or "An Excellent Ballad of St. George and the Dragon" is a 17th-century ballad that considers the account of England's patron saint, St. George, and his infamous defeat of a dragon.  Printed on a broadside, "St. George and the Dragon" is a ballad with less of a narrative about the St. George and the Dragon episode in the Romance genre, and more of a continued assertion that St. George's defeat of the dragon is the most heroic episode in known myth or history.  The collections of various libraries house surviving copies of the ballad printed on broadsides, including the British Library, the National Library of Scotland, and the Huntington Library.  Online copies of the ballad facsimiles are also available.

Migratory woodland caribou: The migratory woodland caribou refer to two herds of caribou, that are included in the migratory woodland ecotype of the subspecies "Rangifer tarandus caribou" or Woodland caribou.  that exist in Nunavik, Québec and Labrador, the Leaf River Caribou Herd (LRCH) and the George River caribou herd (GRCH), south of Ungava Bay.  "Rangifer tarandus caribou" is further divided into three ecotypes: – migratory barren-ground ecotype, the mountain ecotype or woodland (montane) and the forest-dwelling ecotype (boreal caribou).  The "George River herd which morphologically and genetically belong to the woodland caribou subspecies, at one time represented the largest caribou herd in the world and migrating thousands of kilometers from boreal forest to open tundra, where most females calve within a three-week period.  This behaviour is more like barren-ground caribou subspecies."  They argued that "understanding ecotype in relation to existing ecological constraints and releases may be more important than the taxonomic relationships between populations."  The migratory George River caribou herd travel thousands of kilometers moving from wintering grounds to calving grounds near the Inuit hamlet of Kangiqsualujjuaq, Nunavik (also known as George River hamlet).  In Nunavik, northern Québec and Labrador the caribou population varies considerably with their numbers peaking in the later decades of each of the 18th, 19th and 20th centuries.  In 1984, about 10 000 caribou of the George River herd drowned during their bi-annual crossing of the Caniapiscau River during the James Bay hydro project flooding operation.  The most recent decline at the turn of the 20th century caused much hardship for the Inuit and Cree communities of Nunavik, who hunt them for subsistence.
