I have a couple not yet mentioned. I've read most of the books previously noted. One of my very favorite reads is not from a book, but a magazine: Gray's Sporting Journal, the Upland Birds edition, Volume 2, Issue 4, 1977. When I got married and got a decent job, this magazine became a favorite. Two stories from the above mentioned issue still stand out--"Prairie Queen" by Jack Curtis, in my opinion one of the finest short stories I've ever read; and the other very close second in that issue, "There's Always Tomorrow" by John Hewitt. I reread these 2 stories prior to every pheasant opening day.
Another fine book is "The Best of Nash Buckingham" by the noted outdoor writer George Bird Evans. This work is an anthology of Nash's decades of shooting in the Deep South. Nash concentrated mostly on waterfowl and quail, and he shot a helluva lot of birds. On ducks he used a 12 gauge overbored Fox HE side by side, choked "full and fuller"--he was an excellent wingshot.
For you grouse hunters out there, George Evans also wrote the excellent "An Affair With Grouse". He shot a Purdey 12 gauge and raised a noted line of English Setters.
An author you don't hear much about today but who was popular in the mid-20th century--Archibald Rutledge, a college professor who owned a plantation in the Santee Delta in South Carolina. He hunted quail, grouse, turkeys, waterfowl and other game in what was then something of a wilderness wetland. One of my favorites is his "Hunting & Home in the Southern Heartland". A favorite story in that book is "A Great Serpent."
And, for you Upper Midwest hunters, who can forget "The Gordon MacQuarrie Sporting Treasury"? One of my favorites from that work is "Ducks? You Bat You!"
I can suggest more literature but this is a good start.....
