The Xantus’s Hummingbird. These birds were named after the Hungarian naturalist, JohnXantus. John Xantus (October 5, 1825 – December 13, 1894) collected and named many previously unrecognized animals and plants in the southwestern U.S. and Mexico. John Xantus was born in 1825 of a well-to-do middle-class Hungarian family. During the revolution of 1848, he fought with the rebels against the Austro-Hungarian government and had to go into exile as a result. He fled by way of Amsterdam to England, and thereafter, in 1852, to the United States.
|In 1859 Baird arranged for Xantus to make an expedition to Baja California, which was then almost unknown. On this trip he set up a base of operations at Cabo San Lucas at the extreme southern tip of the Baja Peninsula. Thence he explored the entire surrounding region as well as many of adjacent islands. Baird commented that during this time Xantus collected “many new species” then unknown back at the Smithsonian, not only of birds, which were his first interest, but also of plants and animals of almost every other description. Baird stated that during this trip Xantus made “the addition of a larger number of new animals to our fauna than has been made by one person. After his return from Baja in 1861, Xantus went to work for the U.S. Department of State and in the following year was sent to the American consulate in southern Mexico. However, two years later, due to the French intervention that took place in Mexico, the consulate was closed and Xantus decided to return to his native Hungary.|
