Since my teen years, I have read different accounts similar to mine (in sporting magazines or newspapers) where a grouse bonded with other humans, and I can always remember thinking: "How cool would that be?"
Well, this little fella has spent hours together with me this fall doing chores and/or hunting, and he's getting ever more comfortable around me (and the wife). Although he won't let me pet him or feed him (yet), when I go into the woods behind the barn he comes running to me like a puppy and stays by my side (about a foot away) until I go in the house. I talk to him like a pet (telling him what I am doing out there) and he talks back to me (making cooing noises); obviously these are not Dr Doolittle type communications, but I think this limited communication is what has given him his ever increasing confidence around me.
Les commented with the single word "cool"... Tom and Mike also used "cool" within their posts... and let me say firsthand, this experience is undoubtedly VERY "cool".
