The word "deadfalls" is a term used to describe traps used for hunting or capturing animals. Its antonyms would include terms that describe methods of hunting or capturing animals that do not involve the use of traps. Examples of such antonyms could include hunting with a bow or gun, fishing with a rod and reel, or simply tracking and capturing animals without the use of any tools or weapons. These non-trap methods of hunting and capturing animals rely on skill, patience, and knowledge of the animals' behavior, rather than relying on the brute force of a trap.
