I am not a warden or lawyer and I didn't sleep in a Holiday Inn Express last night; but, this is what I know about the questions that have been asked.
Daily = Daily Doesn't matter where you shoot it, you get 1 limit per calendar day not matter how many licenses you have or which states.
Field possession limit = 3x daily bag limit unless otherwise restricted through special regulation (i.e., if you have a swan tag allowing 1 swan/year, you better not get caught with 3 dead swans in the field).
Possession limit currently = 3x daily bag limit. This was changed to match Canada's possession limit. You are allowed to bring a full possession limit of foreign country into the United States as long as it was legally taken, does not exceed the daily bag limit or possession limit in that country, and that you retain a fully feather wing attached to the meat. I have imported cleaned breasts with 1 wing attached to each breast on numerous occasions. I also tag each bird/breast with name of hunter, license number and species name to facilitate filling out the importation forms at the border. Possession terminates upon consuming the birds, gifting them properly, or processing them at your personal abode. This possession limit can extend to your home freezer when they are trying to convince a Federal judge that you are a bad bad person. If they are going through your freezer then they have a search warrant and they are looking for everything you've every done wrong.
A search warrant may or may not be needed in the field. If a warden encounters you in the field and suspects that you've been hunting (probable cause), they can ask for you to produce your license, stamps, authorizations and any harvested game (it doesn't matter if its a Federal or State regulated species, since your hunting license has a standard clause on the bottom that you sign certifying that you agree to produce all licenses, tags, records and your drivers license to designated officers if requested. Its a condition of sale for every license. However, a warden probably would need a search warrant to go through your car, boat, decoy bags or other gear if (a) your license and tags were in order, that your gun was not capable of holding more than 3 shells and your all your visible ammo was non-toxic shot and you didn't have clearly visible harvested game or (b) you refused their verbal request to look in or through your vehicle/boat/gear.
