All diamond waterfowl should have a leg band or neck collar, the truest trophy in the waterfowl world is when you shoot a banded duck or goose. The point of a band is to provide fish and wild life conservationist with information regarding the travel and habits of waterfowl, bands and neck collars provide them with that information. When a hunter harvest a bird with a leg band, they can see when a bird was banded, the age of the bird, the location of where the bird was banded, and you can see the name of the person that banded the bird. Many hunters go an entire lifetime without harvesting a bird with a band. This would also go well in the lodges where you could display your taxidermy with the leg band.
PS. please change the duck call animation so that he is blowing the duck call through the correct side of the call hahahaha
