National Geographic : 1963 Jan
Mr. Greenewalt, with whom he has collabo rated since 1956 (see article beginning on next page). Dr. Ruschi says, "Brazil is too big for any one to say that all the flora and fauna of a given area have been described. I am certain that we shall continue to find new species for a long time to come." "Augusto Ruschi, Naturalist" As I write this in the guesthouse of the Mello Leito Museum of Biology in Santa Teresa, a sudden movement catches my eye. Beyond the plate-glass window, a green hum mingbird hangs suspended six inches from my face and stares at me impudently, as if to ask, "What do you know of me?" Thanks to the patient observations of many men over many years, and modern techniques such as high-speed photography and electron microscopy, we already know a great deal. But just as surely we shall con tinue to learn even more through the bril liantly intuitive studies of the man who signs himself simply, "Augusto Ruschi, naturalist." THE END "Extinct" hummingbird, Augastes luma chellus, the hooded vizor bearer, entertains Andre and Augusto Ruschi, sons of the man who rediscovered the lost species. Green throat and blue side feathers mark Colibri delphinae greenewalti, a subspecies discovered by Dr. Ruschi and named for his friend Crawford H. Greenewalt, dis tinguished author of the article that follows.
