Hunters usually target species that want resource investment disproportionate to associated health rewards. Expensive signalling theory provides a possible description, proposing that hunters target species that impose high costs ( ag e.g. greater failure and damage dangers, reduced consumptive returns) given that it signals a capability to soak up expensive behavior. If expensive signalling is pertinent to modern ‘big game’ hunters, we might expect hunters to cover greater costs to hunt taxa with greater recognized costs.
