Shoulder mount field care...
Do not gut the bird. Rinse any blood from the feathers with water. Take the bird immediately to your taxidermist or freeze it. Put the bird into a plastic bag for freezing, being careful not to damage the feathers, including the tail. If the bird's tail feathers do not fit in the bag, do not bend them. Let the tail stick out of the bag and tie the bag loosely.
Do not gut the fish. It's best to make sure the fins are laid down against its body then wrap the fish in a wet towel and freeze it- this will help protect the fins
Do not gut the animal. Take the animal immediately to your taxidermist or put the animal in a plastic bag freeze it.
