Different categories, with some overlap. Here at Maggie's, we are sometimes busy with preserve hunting of pen-raised birds. Not the real thing but good for the dogs. Sort of Disney hunting. Golf with firearms is the way I think of it.
My love is grouse hunting in the North Woods. BD is the same. Hours of tramping over hill and dale and marsh, hoping to find a stray grouse or woodcock. With dog, of course, preferably pointer. You barely need 12 bullets in your pocket for a whole day and if you come back to the lodge with a grouse or two, it's a banner day.
Both strenuous activities require layering and you need to add an inch to your trousers to handle cold weather under-stuff. Also, if age adds an inch (which it should not, God forbid), take it into account too. Best thing: suspenders. Filson tincloth winter gear requires them. This gear is not for "bird" hunting in the southland but it is good for brush-busting in the northern regions.
Hiking, especially mountain hiking, keeps you warm and you peel layers off into your daypack as you begin to sweat. Bird hunting is slower and colder, more methodical, tactical, and there is no daypack to put stuff into.
Duck and goose hunting is another story entirely.
What is your experience?
