Trails by Fire, the nomnomnom edition.

Hey Everyone! I hope you’re getting excited about our upcoming public walks! Trails by Fire, 24 August, happened last Sunday and it was awesome to see the great lengths that BES Drongos have improved since the start!

Look at all the Drongos diligently guiding their fellow Drongos!

The weather was the typical unpredictable Singapore weather with odd drizzles in the middle of the trail. Thankfully, there wasn’t lightning and the drizzles were short so we pushed on. We managed to see some animals particularly the Malayan Blue Coral Snake and Malayan Pit Viper which we had seen previously on our trails. However, this post will be about something that we haven’t talked about, something that will satisfy our stomach…

NOMNOMNOM.

You guessed it: Fruits! While we humans cannot consume all the fruits of the forest, they are nonetheless a source of food for the creatures of the forest. Here are some the fruits we spotted along the trail:

GoldenHairyFig_petai_24Aug-8681

These Golden Hairy Figs (Ficus aurata) crowding at the base of the leaf does sort of look like a longan, doesn’t it? However, they are in a completely different family as their fellow tropical fruits and are inedible. This particular fig-tree can be distinguished by its distinctive stiff golden hairs that cover its leaves and fruits. It isn’t just the nickname that reflects this fig’s characteristic nature. In fact, it’s latin name, aurata, meaning glided with gold also hints at the golden hairs found on the plant. This shrub is common throughout Singapore so try to spot this enchanting tree if you can!

HairyClidemiaFruit_petai_16Aug-8560

Here’s another hairy fruit: the berry of the Hairy Clidemia (Clidemia hirta). This plant is extremely common throughout Singapore and can be found on the outskirts of forests. You can easily recognized it by its hairy leaves! These sweet dark purple berries are a favorite of birds and as you can guess, are dispersed by animals. This berry is supposedly edible and taste like deeply favoured blueberries. However, one should try it with caution as you could get a stomachache.

We have encountered this particular plant many times on our trails so to read more: click here and here.

ChewingGumTreeFruitpetai_24Aug-8674

This woody pod is not actually a seed as some of you might think; it is actually a fruit! It is the unopened seed pods of the mighty Chewing Gum Tree (Dyera costulata) or perhaps a name that you might be more familiar with: Jelutong. Well, you might be astonished to find that this brown, stiff pod is actually a fruit since we are all used to seeing our typical juicy and fleshy fruits in the supermarkets.

This is due to the mode by which the seed is dispersed from. As you can observe, this unappetizing fruit is probably not going to attract any animal to eat it. Instead, this tall tree (can grow up to 60m!) disperses its seeds via wind. The seedpod will usually open high up in the tree canopy, releasing winged seeds which will be scattered by the wind. It is similar to how your clothes sometimes fall from the bamboo poles. They are rarely found directly under the pole but some distance away!

NibongPalmFruit_petai_24Aug-8637

This blueberry lookalike is actually the fruit of the Nibong palm (Oncosperma tigillarium). The Nibong Palm is usually found in clusters near water bodies and is distinctive due to its black spine on the stem of the trees. Though the berries might look delicious, they are likely to be inedible so don’t eat them if you see them! However, should you need food desperately, the heart of the palm (inner core of the palm) can be eaten raw or cooked with coconut sauce. Yum!

RattanFruitpetai_16Aug-8533

This colorful, scaly fruit is from the Rattan palm (Calamus sp.)  The fruits shown above aren’t ripe yet, but they will soon take on various shades of brown. While we cannot eat it’s fruits, it is still important in the musical world!. Some of the fruits of the rattan will exude a red resin which is called, interestingly, Dragon’s Blood. It is currently being used as a vanish for violins. There are even more common uses for the rattan palms itself how the skin of rattan strands can be weaved into baskets, “cores” made into furniture and perhaps the one we are most familiar with: the rattan cane our parents used to smack us with.

RubberSeedAndLeaf_petai_16Aug-8525

Last of all, this striped dark and light brown seed is a Rubber Seed (Hevea brasiliensis). It might look innocuous but the capsule (fruit that contains the seeds) actually exploded to throw this seed as far as possible from the parent tree. Though this seed looks rather unextraordinary, the struggle to bring these seeds out of Brazil (the native country) is fraught with bio-piracy, controversy and blood. This makes a fascinating read if you can spare the time.

Well, I hope you have been enlightened about the seeds and fruits of our forest. We’re be going about our trail soon again so do look out for our next misadventures.

Discoveries on our Trail by Fire!

Hello everybody! The BES Drongos are quickly gaining traction as they begin their first edition of Trail by Fire – a series of trails where selected members of the public (aka our friends) to join our walks and add that little bit of authenticity to our practice walks. Why “Trail by Fire”? It’s a pun on ‘trial by fire’, nature trail style.

Trail by Fire Group Photo

Last Saturday’s trail saw us encountering new biodiversity, particularly birds! It was the first time that we, the BES Drongos, encountered our namesake – the Greater Racket Tailed Drongo! Its scientific name is Dicrurus paradiseus. The drongo is an immensely interesting bird, and not just because they are our mascot animal. They are visually very distinctive as they have a pair of long unique tail feathers called “rackets” as seen from the photo. They are excellent mimics and can imitate the calls of a variety of other birds, although they tend to attach a metallic ring to the end of the call, which is unique to this bird.

This picture of the drongo was captured during another trail at the Venus loop of the Macritchie Reservoir Park.

Drongos are also sneaky creatures. They are known to practice kleptoparasitism, which means that they often steal prey from other foraging animals such as macaques. One of their favorite tricks is to follow a flock of birds like babblers, and then make an alarm call to scare the foragers away while the drongo picks up the spoils. This is the story behind the BES Drongos’ tagline, “Follow that monkey!”. 

Trail by Fire Entrance

As we were walking through the trail near the entrance to the Petai Trail, we heard a distinctive call that reminded us of a rooster. These were the calls of Red Jungle Fowl, also known as jungle chickens! Red jungle fowl are essentially the ancestors of our domestic chickens, and can be distinguished from them by their white ear flaps.

This picture of the red jungle fowl was captured during another trail at the Venus loop of the Macritchie Reservoir Park.

Red jungle fowl also distinguish themselves from their more placid descendants in that they can fly, often flapping their way up trees to escape predators! Their call also differs from domestic chickens in that the end is cut off (sounds kinda like it has a sore throat). An excellent example of this call can be heard in the Youtube video below:

Blue-throated Bee Eater

This beautiful bird perched on the tree overlooking a large water body near the end of the trail is a Blue-throated Bee Eater. This bird is not a permanent resident of Singapore. Instead, it migrates around the SEA region seasonally. They normally visit during their breeding season, although they are sometimes also classified as uncommon winter migrants (that means that they spend time here during winter, but rarely). They are insectivores that favor flying insects, and the one that we saw was eating dragonflies that it picked off from the surface of the water. When taking venomous prey or prey with stings, they will “wipe” their prey against their perch to get rid of the venom or sting. This is probably where they get their name from; they basically specialize in eating stinging insects that other birds find unappetizing.

The photo below is of a bird that is as yet not properly identified because it is unclear, but we suspect that it is a Pin-Striped tit-babbler. During the trail, we may have also seen a forest babbler but failed to get a photo.

petai_16Aug-8536

Babblers are common residents in most of our nature reserves in Singapore, including the Central Catchment Nature Reserve. They can be noisy little birds with a distinctive and repetitive call, as seen in this Youtube video:


Babblers are important to note because they are one of the vulnerable bird groups that could be affected detrimentally should the Cross Island Line be built through the Central Catchment Nature Reserve. This is because certain species like Abbott’s babbler can only live in the lower story of mature secondary or primary forest, which is obviously quite scarce in rapidly urbanizing Singapore. Because of their small size, these birds also dislike flying across large open spaces. As fragmentation occurs due to the building of developments across the nature reserve, these birds are unlikely to travel between forest fragments. Thus, their breeding potential is limited and their gene pools are reduced due to less mixing between populations.

Trial by Fire

We hope you have enjoyed this short sharing on some of our discoveries on the Petai Trail at Macritchie Reservoir Park. Each trip is an eye-opening experience and as you can tell from our posts, we never cease to find something new and unexpected each time! More Trails by Fire will take place over the next few weeks. We will be providing more information on the impacts that developments within nature reserves can create, such as forest fragmentation and soil disturbance in future blog posts, so keep an eye out for them. For now, pop by the Love Our Macritchie Forest website, run by the Toddycats, to find out more about how the Cross Island Line can impact the Central Catchment Nature Reserve.
