I guess I will have to correct myself. The Philippine cobra occurs mostly in the northern regions of the Philippines. They can be found on the islands of Luzon, Mindoro, Catanduanes, Azria, and Masbate. This species likely may occur in other neighboring islands, but this remains unconfirmed. Records from the Calamianes group and Palawan require confirmation
While flying island to island by helicopter during the '90s. We were often told by Philippine forces, that the Philippine Cobra did indeed exist on Negros. To include Dumaguete. So when we stepped out at night into a landing zome, to be extra careful.

 

"It is mostly found in moist forests and can cover a horizontal distance of about 100 meters in a glide from the top of a tree. Slow motion photography shows an undulation of the snake's body in flight while the head remains relatively stable, suggesting controlled flight. They are mildly venomous with rear fangs and also can constrict their prey, which consists of mostly lizards and bats."

Cool! A local poisonous snake that flies!
