Passage: The spotted green pigeon or Liverpool pigeon (Caloenas maculata) is a species of pigeon which is most likely extinct. It was first mentioned and described in 1783 by John Latham, who had seen two specimens of unknown provenance and a drawing depicting the bird. The taxonomic relationships of the bird were long obscure, and early writers suggested many different possibilities, though the idea that it was related to the Nicobar pigeon (C. nicobarica) prevailed, and it was therefore placed in the same genus, Caloenas. Today, the species is only known from a specimen kept in World Museum, Liverpool. Overlooked for much of the 20th century, it was recognised as a valid extinct species by the IUCN Red List only in 2008. In 2014 a genetic study confirmed it as a distinct species related to the Nicobar pigeon, and showed that the two were the closest relatives of the extinct dodo and Rodrigues solitaire.
 Link Information: The animal order Columbiformes is also constituted of pigeons and doves, and includes about 42 genera and 310 species.
 Question: How many species of pigeons are there?
Answer: 310

Passage: An avid sportsman, Pierre Lorillard and his brother, George Lyndes Lorillard, were both major figures in Thoroughbred horse racing. In 1874, Pierre's horse, Saxon, won the Belmont Stakes. Although his horse Parole finished fourth in the 1876 Kentucky Derby, it went on to race with considerable success both in the United States and in Europe. In the 19th century, shipping horses from New York to Louisville, Kentucky was a major undertaking and as the Preakness Stakes and the Belmont Stakes were both held in the New York City area in the period, neither of the Lorillard brothers entered horses again in the Kentucky Derby. Pierre Lorillard established Rancocas Stable, named for the New Jersey town where he owned a country house. He spent time in Paris and in England where, in 1881, his horse Iroquois became the first American-owned and bred horse to win a European classic race. Ridden by the champion English jockey Fred Archer, Iroquois won The Derby and then went on to capture the St. Leger Stakes as well. Lorillard had other successes in England, notably with the horse named for the actor David Garrick, which won the 1901 Chester Cup ridden by American jockey, Danny Maher.
