"Bothriechis schlegelii," Wikipedia, the free encyclopedia. Like other Bothriechis members, B. schlegelii is arboreal and has a strong prehensile tail. It is largely nocturnal, consuming small rodents, frogs, lizards and small birds. It is not known to be an aggressive snake, but will not hesitate to strike if harassed. A typical ambush predator, it waits patiently for unsuspecting prey to wander by. Sometimes, it is known to select a specific ambush site and return to it every year in time for the spring migration of birds.
