Hi, my name is Andre Wille. For as long as I can remember, I have been fascinated with the mysterious continent of Antarctica. I also have a passion for birds. When I learned that I would have the opportunity to study penguins in Antarctica, I was pretty excited. My interest in birds (as well as natural science in general) has taken me to many places around the world. I have worked in such locations as the California coast and the upper Amazon. In California I worked with the Peregrine Fund returning peregrine falcons to the wild. On the head waters of the Amazon I worked in a place called Manu, learning about the reproductive biology of parrots. These experiences and others have had a very powerful effect on my life. Ten years ago I decided to become a high school teacher so that I could share my love of biology as well as my concern for the world's vanishing wild places. Since that time, I have worked at Basalt High School teaching biology, chemistry, and physical science.

In addition to my interest in the sciences, I am very active in wilderness pursuits such as rock and ice climbing, high altitude mountaineering, back country skiing and white water kayaking. With my wife and two daughters (ages 2 and 6), I also enjoy hiking, skiing, and rafting. Living in the mountains of Colorado, these activities are all just out the back door. At my school, I sponsor an outdoor club to expose my students to the wild playground and outdoor classroom that surrounds us. I find that when my students experience nature first-hand, they really appreciate what we learn in the classroom.



Factors Regulating Population Size and Colony Distribution of Adelie Penguins
Dr. David G. Ainley, H.T. Harvey & Associates

In Antarctica, I will parcticipate in research on Adelie penguins with Dr. David Ainley of H.T. Harvey and Associates. Dr. Ainley is interested in identifying the factors which regulate population size and colony distribution of Adelie penguins. Some of the factors we will be investigating include: the availability of nesting habitat and food, competition with other species of penguins, and the effects of climate change which has resulted in recent changes in pack ice in the Ross Sea.

To analyze these factors, we will utilize a number of recent technological advances. The pack ice distribution which is critical to food availability is monitored by satellite photographs. Aerial photos are used to evaluate the availability of nesting habitat. Radio telemetry is used to track penguins to their feeding areas. Finally, a new system using an automated electronic balance with computerized data collection, will be used to record body mass before and after feeding trips. These trips involve long swimming distances and can take 24 hours or longer. Information obtained in this study will help answer the basic questions; why do neighboring penguin colonies differ in size and why are new colonies founded?
