John Xantus was a Hungarian Zoologist who was exiled in 1851 and came to live in the United States. Here he went on to give his name to a number of animals, so many that I could probably fill a (relatively small) encyclopedia volume with his X's alone. Among these discoveries were this, the Xantus's Hummingbird.
The Xantus's Hummingbird is endemic to Baja California, although he sometimes strays up the west coast to Canada during the summer months. Like most hummingbirds, his diet consists predominantly on nectar, supped in flight with his extendable tongue. He is also noted to take insects on the wing, especially when feeding offspring. The nest is cup-shaped and lined with feathers, spiderwebs and animal hair, with the outside including moss for camouflage. In this the female lays two eggs.
