His interest in animal behaviour and ecology were formalised while an undergraduate student at the University of Wisconsin, Oshkosh, where he studied with the late Dr Jacob Shapiro.

He received his Master of Science and Doctor of Philosophy Degrees from the University of Illinois under the late Dr S. Charles Kendeigh. His doctoral dissertation dealt with the breeding birds of the Chiricahua mountains in southeastern Arizona.

He is currently studying spatial memory and cognition in seed-caching birds. These studies have been in progress for the past fifteen years.
