 Commercialisation and modernisation of hunting practices has led to a focus on shotgun use over trappings, as these methods are more lucrative.Additionally, growing infrastructure on Bioko Island has allowed a faster return rate for hunters and intermediaries for the market, who are often taxi drivers, allowing for faster travel and reward.The Bioko drill is a popular target amongst bushmeat hunters, and increased prices of the drill as its population declines has been speculated to encourage hunters to seek it out in increasingly remote areas, furthering its decline.
