Well, I became interested in ornithology I suppose, because birds are so remarkably diverse, so active, and my original interest in reptiles is still very strong but if you’re a herpetologist and I suppose I was better qualified as a herpetologist than anything else when I became interested in ornithology, you soon realize that they’re pretty boring in the place like St. Louis in the winter time when they all are hibernating and their range of activity is not to be compared or their diversity in that area, which, that of birds. So I found birds, absolutely marvelous representation of life, as it interested me and by studying birds and their enormous ranges, their migrations from Arctic to Antarctic, the global perception one obtains is, really very helpful in giving one insights in what is happening to nature. So, I guess I’m not on all unhappy with my eventual focus on birds, but I have to say I’ve done quite a bit of work with mammals too. So now you are hired by the New York Zoo Society.
