I visited the Philipines in November 2015 for a work trip and spent a couple of weekends mammalwatching. See the 2015 Trip Report for full details.
During 2 nights November 2015 I saw Philiipine Colugo (Flying Lemur), Spinner Dolphins and Philippine Tarsier.
The island is also good for bats and we found Greater Musky Fruit Bat, Asian Sheathtail Bat, Diadem Horseshoe Bat, Philippine Dusky Roundleaf Bat, Philiipine Pygmy Roundleaf Bat.
A 2 hour visit to Subic Bay in November 2015 produced some fabulous Golden-capped Flying Foxes and some Giant Flying Foxes, Long-tailed Macaque.
I spent 2 nights in November 2015 and saw the critically endangered Tamaraw.
