To understand the setting of the discovery and of the early voyages to Brazil we must go back to some of the circumstances which preceded, and review the conditions in Europe at that time. The discoveries of the Portuguese navigators mark an epoch in world history. Had Columbus not persuaded the Spaniards to finance his voyage to the Spice Islands by a western route, the Portuguese might easily have claimed the discovery of both North and South America within a decade following Columbus’ landfall. Both continents would probably have been visited in 1500 when Gaspar Corte-Real reached Newfoundland and Pedro Alvares Cabral, Brazil. The former voyage was but a continuation of others westward over the Atlantic and the latter was only an incident in the Voyages to India. Furthermore, the delusion of reaching Asia would have been avoided. The exploration of the Americas would then have been carried on in an orderly manner with the realization that a new world had been found. However, the Portuguese are not best known for their voyages to America, but for the first accurate knowledge of both the West and East coasts of Africa, of the Indian Ocean and of the Spice Islands. They continued these voyages even farther, up the coast of China, and in 1542 they were the first Europeans to set foot in Japan. These achievements, of which any nation might justly be proud, were made by a country which then numbered between one and two million people.

Gerald Handerson Thayer (1883–1939) was an artist, writer and naturalist who worked in North and South America, Europe and the West Indies. In the Lesser Antilles, Thayer made substantial contributions to the knowledge and conservation of birds in St Vincent and the Grenadines. Thayer observed and collected birds throughout much of St Vincent and on many of the Grenadines from January 1924 through to December 1925. Although he produced a preliminary manuscript containing interesting distributional notes and which is an early record of the region's ornithology, Thayer never published the results of his work in the islands. Some 413 bird and bird egg specimens have survived from his work in St Vincent and the Grenadines and are now housed in the American Museum of Natural History (New York City) and the Museum of Comparative Zoology (Cambridge, Massachusetts). Four hundred and fifty eight specimens of birds and eggs collected by Gerald and his father, Abbott, from other countries are held in museums in the United States.

In a spirited treatise on the ‘Origin of our Animal World’ Prof. L. Rütimeyer, in the year 1867, described the geological development and distribution of the mammalia, and the relationship of the different faunas of the past with each other and with that now existing. Although, since the appearance of that masterly sketch the palæontological material has been, at least, doubled through new discoveries in Europe and more especially in North and South America, this unexpected increase has in most instances only served as a confirmation of the views which Rutimeyer advanced on more limited experience. At present, Africa forms the only great gap in our knowledge of the fossil mammalia; all the remaining parts of the world can show materials more or less abundantly, from which the course followed by the mammalia in their geological development can be traced with approximate certainty.
