Abstract
I represent several areas of concern regarding the
importation of exotic animals into the United States.
I am primarily a Professor of Biology, a zoogeographer
and ecologist, and I am well aware of the history and
ecology of alien species. As a Director of the San
Francisco Zoological Society and involved in educational
and research programs at the San Francisco Zoo,
I have a deep interest in the functions of zoos. I am
also involved in aviculture both as a research zoologist
and as a breeder of birds.
