Answer: they hunt at night and hunt rats, birds, monkeys, or wild pigs.
Explanation: they like hunting at night so that they can see preys and sneakily eat them and Boa constrictors are able to adjust their hunting behaviors according to the density of possible prey items in their habitat. In most cases, they are ambush predators, meaning they sit and wait for a desirable prey item to pass by. However, if food is scarce, they become more active to seek out prey.
