We have been on many adventures with David as a leader, both short domestic trips and long-term International ones. We have always learned a lot and had a great time. His knowledge of birding, especially by ear, is phenomenal. His enthusiasm to share his expertise in all areas of natural history is contagious.
It is so impressive how David knows so much about about many aspects of Nature. I learned so much about birds and their environment. I would highly recommend David,
David sure knows so much about everything! He makes me want to study more!
David is not only knowledgeable but has a wonderful way of educating the young and old alike.
