Northern Sierra Madre Forest Monitor

This massive lizard lives high in the canopy of the Sierra Madre Forest on the island of Luzon. Growing to lengths over 2 meters, the Northern Sierra Madre Forest Monitor is recognizable by its black body covered in golden yellow flecks and dots. Its tail features alternating segments of green and black, while its legs display a blue-black color mottled with pale yellow-green. These shy reptiles are difficult to spot because they spend the vast majority of their lives in trees, often staying more than 20 meters above the forest floor.

Unlike most of its relatives, this monitor primarily eats fruit. It relies heavily on Pandan palms and Canarium, though it also consumes snails, insects, and sugary berries. Because it can digest fruits that contain high levels of toxins, it serves as a vital seed disperser for local plants. Despite its size, it remained unknown to scientists until 2010, though indigenous groups have long known it as the bitatawa.

Today, these lizards face significant pressure from humans. They are a prized target for hunters who seek them for personal consumption or the bushmeat trade, and they are occasionally captured for the illegal pet market. Because the species requires large trees to survive, selective logging and deforestation are major threats. New road construction also fragments their habitat, making the forest more accessible to farmers and loggers while bringing human activity into areas where these reclusive monitors cannot thrive.
