On the other hand, it is common in some protected areas, where populations appear to be doing quite well. This is an arboreal species that spends its time in the thick foliage of forest trees and shrubbery. It is often found at the base of palm fronds. These snakes prefer to remain coiled and still, relying on their camouflage to avoid detection, rather than defending themselves aggressively. However, they will strike quickly if touched. The prehensile tail is not only used as an anchor when resting, but also when it strikes out to grasp its prey, which consists of small birds, rodents, lizards and frogs. Bites can be serious, but fatalities are rare. A polyvalent antivenin that covers this species is produced by the Instituto Clodomiro in Costa Rica.
