You are indeed lucky/blessed, to have such a mentor and friend as Mr. Hochbaum. I cannot begin to imagine the impact it would have on a young waterfowl student.
I agree about more waterfowl hunters reading his books. It only stands to reason that one would want more knowledge about the birds they think about almost everyday.
 Also the works of Frank C. Belrose, and Francis H. Kortright. Having a well rounded library is essential to being a waterfowler. The hunger to learn more never ceases until we are planted.
When I give friends a copy of a Sand County Almanac, they read it. When I offer the other books mentioned, they are not so enthusiastic. To much homework maybe, I dunno.
When I moved to NY at the age of 60 1/2, a longtime waterfowler & decoy carver. I had to take a Waterfowl ID Course, if I wanted to hunt certain public areas. You must show a card proving you passed the course, or no hunting for you. 
Anywho, I had to take the course with youngsters, as it was the only course left before the season. It did not bother me at all, but two other older guys were not so happy. Long story short, even as a Geezer waterfowler I learned things and had a very good experience.
As a child I made my wish list as to the waterfowl that I wanted to hunt, near and far. Swans were never on the list. As their call and sight of them was spiritual no matter when, or where. I count my years on earth with the migrations of Swans. I can sit with binoculars and sketch pad and watch them for hours. They appear one day and are gone the next.
Hunting Swans is indeed exciting, but to touch the trigger I cannot.  To those that do I wish you the best.
