Tarsier Territorialism

By Tom Lumapas

If you have a chance to visit the Tarsier Sanctuary located in the town of Corella, Bohol and decide to see the Philippine Tarsier (C. Syrichta) for yourself, please don’t fret if you only see a few Tarsiers in the enclosure. There is a very good reason for this and one should not be disappointed if one finds the furry prosimian (it’s not a monkey!) few and far between. Information gleaned from the Carlito Pizarras, the “Tarsier Man”, adds light to this frustrating mystery.

The Philippine Tarsier is, unlike some of its Southern cousins, is a very territorial animal that prefers its isolation. Unlike other primates, such as humans that prefer to socialize with other individuals, the Philippine Tarsier loves its personal space. At a whopping 1 hectare per individual it’s no small wonder why these Tarsiers are so difficult to find and pretty alone to boot.

Of course, one might ask how such a small animal could claim a whole hectare as its personal living ground. Well for the most part the Philippine Tarsier, despite having the biggest eye to body ratio of any animal in existence, cannot personally monitor every tiny inch of the whole one area so it is highly likely that the 1 hectare of Tarsier A and the 1 hectare of Tarsier 2 are overlapping. Since the Tarsier takes nightly hunts for food and mates it is not surprising that some intrusions are never noticed and Tarsier A and Tarsier B are only vaguely aware of the existence of the other. If a chance meeting does occur then one tarsier will be forced out of the immediate vicinity at risk of death.

The male Philippine Tarsier is the more solitary of the two sexes as he will attack any male he finds in his territory during his nightly patrols. If he can’t chase the rivals away, he’ll resort to killing his rivals with a quick bite to the neck after wearing them down. The male might even ungentlemanly attack females in his territory if he finds them unattractive or unable to mate with him. The male will mark his territory with a variety of actions ranging from the classic poo droppings to urine sprays. However, the male has a special scent gland located near the stomach called the epigastric gland that it rubs on surfaces to mark its territory.

The female, being the fairer sex, is probably less aggressive and willing to share right? Well, yes and no. It is true that the female is less likely to attack other females she finds in her territory, however this is true only if the environment is abundant with insects. So having satisfied her nutritional requirement and sure that there is more food from where that came from, she will allow other females to enter her territory as long as they return to their respective territory before she sleeps in her area. If resources are not abundant enough, then these females will be just as aggressive as the males, attacking intruders she finds during her roaming in the territory. Similar to the male, the female will mark her territory with fecal droppings and urine. Interestingly though, the mother unleashes a strong scent to mark her territory when she is caring for her toddler and she parks him somewhere to hunt. This serves a dual purpose of directing the toddler back to his mother’s area when the toddler wanders off and warning other tarsiers off the area.

So, don’t be surprised to see two or fewer tarsiers on your visit. You are seeing these animals living peacefully and happily in isolation away from each other, knowing that no other rival will disturb them as they sleep the daylight hours away. After all forcing other tarsiers into a tarsier’s territory where they shouldn’t be in is like forcing another family to live in your family’s living room. You wouldn’t like that at all would you?


As part of GLOBE TELECOM’s TREE GROWING PROGRAM, Philippine Tarsier Foundation Staff and volunteers every other morning plant seedlings along trails and barren areas of the forest.

The trees specially selected by Carlito Pizarras, more famous for the alias “Tarsier man” which serves the purpose as host for INSECTS (Staple food for tarsiers) and as host trees for animals.

The volunteers are from European Union , hosted by YSDA (Marianne), a Spanish long term volunteer (Enrique) and a short term French Volunteer (Quentin) of the Foundation.

This is just one of he series tree plating which totals to 300 host trees! Good for insects, Good for TARSIERS and of curse great for the various species of birds having their home in the forest of the Philippine Tarsier Foundation

It’s a sad but true story… Approximately three weeks ago we’ve discovered that one of our Tarsiers looks a bit different and is nlacking i one eye! Quite fast gained a new name – Pirate. At the beginning we weren’t sure if it will survive in a natural environment. A little tarsier has to hunt for most of the night thus it needs to be in a perfect shape. Tarsier has to be a great hunter in order to catch a big amount of insects. Apparently our pirate is doing well enough, has survived those past weeks and is getting better now.

 A ‘huggable looking’  tarsier at day time, is a great predator at night time! What is surprising, tarsiers can fight with each other, first of all – for the territory, second of all – for the females! And mating season is on now… The two males while fighting in order to charm a female can even kill each other! Cruel but real natural environment is not for the weak ones… But our pirate doesn’t have any other scars or injuries which rather occur right after the fight. Which leads to another theory, it could be just a bad accident or a big beetle bite.

But whatever that was, the good news is he is alive and is doing fine in the natural habitat. Which proves he is in deed one tough tarsier. Animals do do well in their natural environment.

Jungle rulez!

I live and work in Philippine Tarsier Foundation which is basically placed in the jungle.
Just behind the main building of the foundation where all the volunteers stay, there is a sanctuary where our precious tarsiers live. We are in a close touch with jungle and everything which lives there. It basically means that we share our accommodation with all the insects, lizards, snakes and creatures which feel invited to our building ;p
I’m here three months and I can already recognize most of the noises coming from the jungle, especially during the night time when all the animals are easily hearable by us – a real jungle music! I really enjoy living close to the nature and wildlife… To be honest, every time I come back to the jungle from the city I feel like home! 😉
The closest civilization is 15 km far from our foundation, it’s a quite a big city called Tagbilaran. Once per 2-3 days we go there by jeepney or hitch-hiking to use Internet and buy some food in a supermarket or street market.
Living in the jungle has its advantages, as long as you enjoy nature, wildlife and you don’t mind to get really dirty;p

Diving masters (well… almost)

So it happened…

Coming to the Philippines, I was sure that I’d love to take diving course. Now, when two months of our stay as volunteers have passed, finally, a perfect moment to do so appeared.

 All together: the volunteers from Bohol and some extra active ones from Manila ;)) plus our great mentor Joannie, we went to a little paradisiac island called Pamilacan to take a four-day-long course. The weather was perfect, the instructors were experienced and the group was fun – nothing could be any better!

After four days of
diving, sunbathing, reef watching and learning, we passed our exam for Open Water Divers and now all the great diving spots are waiting for us!

Other animals

For us, volunteers of the Tarsier Foundation, Bohol is all about tarsiers. However, there are other interesting animals living here – for example giant bats with a wingspan of 1.5?1.7 m (more info:http://en.wikipedia.org/wiki/Giant_golden-crowned_flying_fox) or Philippine flying lemur (http://en.wikipedia.org/wiki/Philippine_flying_lemur). Obviously, those animals are quite difficult to spot. No worries – if you’re not lucky enough, you may always go to see macaques. Some of them are
crab-eating but for sure they will not resist if they are offered a banana!

Hi! My name is Kamila…

Hi! My name is Kamila and I come from Poland. I’m really happy I can be part of EVS project in Philippines. This amazing country gives me opportunity to be close with nature, get to know other culture and friendly local people. According the project, I work and live in Philippine Tarsier Sanctuary in Corella (Bohol) with other volunteers from Poland, Italy and Spain. Working in sanctuary as a tour guide gives me opportunity to stay close with nature what I really appreciate because I have a  great interest in biology and geography area.

A View from the Top

Photo by Marta Patyra

These are just some of the photos the Polish Volunteers took during the Day Trek and Camping.


The photo above is taken during the early morning where the forest was covered with fog and looked like, well at least to me, a grass with cob webs and dew.


Just before sunset,  beautiful orange and dark clouds with a powder blue background of a sky made the scene almost out of this world, thanks to volunteer Ms. Marta Patyra for capturing the view.


It never fails to remind me of Jurassic Park or Avatar.


These are just some of the views you’ll when you trek to the viewing decks found inside the tarsier sanctuary. But of course, experiencing it is a whole lot different than mere photos.

Experience Day Trekking

Day trekking allows you to explore the tarsier inhabited forest with the added benefit of exercise and breathtaking views.

During noon, it could be hot and humid, thus we encourage trekkers to bring water and even extra-shit. The ground when wet, as it always is especially if you trek before noon, is very slippery thus flipflops certainly will not work.

Since its a forest, trekkers might encounter animals such as snakes thus be very careful with your steps.

There are signages too, but very few thus trekkers must be accompanied by a guide during the entire hike.

You take as may photos as you like. These photos are taken by Polish volunteer, Marta Patyra during the trekking and camping of the foundation volunteers.
