Calamian Deer (Hyelaphus calamianensis)

Bushbuck and impala grazed alongside the indigenous Calamian deer, while endangered species from Palawan, such as the bearcat, a sort of overgrown possum, were confined to cages.

The Philippines also have three endemic species of deer namely the Philippine Deer, the Calamian Deer and the Philippine Spotted Deer.

The park also is a haven for indigenous wildlife like the Calamian deer, named for the Calamian islands, the northernmost island cluster in Palawan province, a group that includes Busuanga.

The Calamian deer, Hyelaphus calamianensis, also known as Calamian hog deer, is an endangered species of deer found only in the Calamian Islands of Palawan province of the Philippines.

This 50-acre island, bordered by miles of white sand, is home to Calamian deer, monitor lizards and a variety of birds, while the surrounding reef is teeming with brilliant coral and sponges, pawikan sea turtles, giant clams and reef sharks.

There are two separate but similar island hog deer species: The Bawean deer (H. kuhlii) of Bawean Island in Indonesia, and the Calamian deer (H. calamianensis) of the Calamian Islands in the Philippines that inhabit moist or dry tropical deciduous forest environments.
