Game meat is a resource widely exploited by rural populations in various parts of the world. In recent decades, the growth in the number of people living near conserved areas has increased the demand for game meat. In this work, based on the Social-ecological Theory of Maximization, we seek to verify the influence of cost-benefit ratio, availability, and subjective preferences (flavor) in the selection of hunted species. We interviewed game-eating people in seven communities in the Brazilian semiarid region, recording information on hunting strategies, flavor preferences, and relative abundance of game fauna. We found that people hunt for the most available species regardless of the cost-benefit of this choice. Also, flavor preference can increase the odds of a species being hunted almost 100%. Our data show that hunters may prefer species that require less capture effort, even though they have energy-efficient alternatives. We found that flavor preference is proportionally the variable with the most significant effect on the chances of a species being hunted, suggesting that traditional optimal foraging models are too simple to cover the complexity involved in the selection of game species.
