Western science has played a fundamental role in the creation of the modern world.1 The emergence of modern science in Europe in the Renaissance accompanied and helped propel European overseas expansion.2 It played an important role in the conquest and colonization of Latin America, and in the "second conquest" in the aftermath of independence in the nineteenth century. Despite its importance, the history of science in Latin America has been inadequately cultivated, especially in comparison to themes such as land tenure, labor systems, slavery, and political power. A few Latin American nations-most notably Argentina, Mexico, Cuba, and Venezuela-have venerable traditions in the publication of works on the history of science that in some cases date back to the beginnings of the discipline in the early twentieth century.3 Only in recent years, however, have North American scholars begun to turn their attention to the history of Latin American science rather than the more intensely studied scientific traditions of Europe and the United States

In a 1924 essay, the botanist Henri Pittier worried that many of Latin America's tropical products—particularly its plants—lacked a ‘civil status.’ By this, Pittier meant that they had not yet been identified and named scientifically. He likened the plants’ lack of a botanical ‘civil status’ to a person's lacking a passport or credentials that proved their citizenship. This was more than a casual analogy. Over the previous half-century, many states in Latin America had begun to take inventories of their plants, just as they had begun taking censuses of their citizens, and surveying and mapping their national territories. These botanical inventories helped states establish control over the natural world, just as censuses helped the state establish control over civil society. Between 1885 and 1935, governments throughout Latin America began to fund botanical research institutions and to finance the publication of national floras. Pittier had been actively involved in this process: he had helped establish national natural history museums in Costa Rica and Venezuela, and wrote or edited three national flora: the Primitiae Florae Costaricensis (1891-1901), the Ensayo sobre las plantas usuales de Costa Rica (1908), and the Manual de las plantas usuales de Venezuela (1926). National floras such as these were not simply ‘entertainment for intellectuals’ but also part of broader programs by Latin American governments to incorporate the natural world into the national political and economic order.

By the 1960s many biologists affiliated with North American institutions were intent upon establishing a new kind of field station within tropical America. Conditions at such new stations contrasted with those at tropical medicine research centers, commodity-oriented agricultural research stations like those run by the United Fruit Company, or established botanical centers such as the Atkins Garden and Research Laboratory in Cuba. Absent were the arboreta, the crop demonstration plots, full-scale expatriate residences and most home comforts. Absent too were the nearby plantations served by the economic botany practiced at the agricultural stations.

Let us keep a place where real research men can find quiet, keen intellectual stimulation, freedom from any outside distraction." This was the response of a prominent North American naturalist opposed to a 1924 proposal to build facilities for women at the Barro Colorado Island Biological Laboratory in Panama. In the first decades of the twentieth-century, in the aftermath of the Spanish-American War and as the United States built the Panama Canal, the American tropics became a major focus for North American politics and natural history, with government funding and logistical support from the military for scientific expeditions. As the North American western frontier closed, the New World tropics—or Neotropics—assumed the role that the West had played for an earlier generation of nineteenth-century explorers. In a post-Darwinian world, a field trip to the tropics with its rich biodiversity had become a rite of passage and a route to fame for young North American naturalists. And in the decades during and after the successful campaign for women's suffrage in the United States, tensions between men and women ran high, in the home, at the ballot box, and at the field station.

Among all the zoological species, birds are the easiest to observe and study. Their diurnal habits, the songs, and visual features make them conspicuous. These characteristics have made birds one of the bestknown animal groups even though ornithologists do not make up a large community among zoologists. For Ernst Mayr, an ornithologist who has made significant contributions that go beyond his own field, the accessibility of birds to research has allowed ornithologists to make important discoveries in several new fields of biology, ranging “from new systematics and speciation research to endocrinology and behavioral biology.”
