Abstract This essay focuses on New World birds caught up in the eighteenth-century transatlantic trade with other living wild creatures, destined for imperial metropoles. Manuscript sources describing this trade, written by political officials, ships’ captains, doctors, naturalists, animal caretakers, and inspectors who cataloged their arrival to Spanish ports, interacted with the animals, tried to keep them alive aboard the ship, and determined their ability to withstand further transport to their final destinations in Madrid and other cities in Spain. In the process, animals caged aboard ship for several weeks or more developed relationships with one another and with their human caretakers. Their lived experiences show the multiple and complicated ways in which individual captured birds and other creatures helped shape those shipboard environments, disrupting systemic human attempts to construct them as colonial animals who functioned solely as scientific or material objects in empire making.

And Migration

The 3rd of August 1492 marked the start of one of the most significant periods of global exploration, travel and migration. Setting sail from Palos on the Portuguese coast, Christopher Columbus, sponsored by King Ferdinand and Queen Isabella of Spain, headed westward bound for the Canary Islands. From the Canaries, Columbus continued his voyage. Thirty-five days after setting sail, he reached the Bahamas. His first landing point, on a small island, known as San Salvador, was used by Columbus as a base to explore and map the islands of this New World, before he and his crew returned to Spain in the spring of 1493.

Female Coloration

The mechanisms underlying evolutionary changes in sexual dimorphism have long been of interest to biologists. A striking gradient in sexual dichromatism exists among songbirds in North America, including the wood-warblers (Parulidae): males are generally more colourful than females at northern latitudes, while the sexes are similarly ornamented at lower latitudes. We use phylogenetically controlled comparative analysis to test three non-mutually exclusive hypotheses for the evolution of sexual dichromatism among wood-warblers. The first two hypotheses focus on the loss of female coloration with the evolution of migration, either owing to the costs imposed by visual predators during migration, or owing to the relaxation of selection for female social signalling at higher latitudes. The third hypothesis focuses on whether sexual dichromatism evolved owing to changes in male ornamentation as the strength of sexual selection increases with breeding latitude. To test these hypotheses, we compared sexual dichromatism to three variables: the presence of migration, migration distance, and breeding latitude. We found that the presence of migration and migration distance were both positively correlated with sexual dichromatism, but models including breeding latitude alone were not strongly supported. Ancestral state reconstruction supports the hypothesis that the ancestral wood-warblers were monochromatic, with both colourful males and females. Combined, these results are consistent with the hypotheses that the evolution of migration is associated with the relaxation of selection for social signalling among females and that there are increased predatory costs along longer migratory routes for colourful females. These results suggest that loss of female ornamentation can be a driver of sexual dichromatism and that social or natural selection may be a stronger contributor to variation in dichromatism than sexual selection.
