Squirrels jump from tree to tree at Bukit Timah Nature Reserve

Squirrels jump from tree to tree at Bukit Timah Nature Reserve
STOMPer Jungle Man would like to share these pictures he took of the interesting wildlife at Bukit Timah Nature Reserve with fellow STOMPers.

In an email to STOMP today (Jul 6), the STOMPer says:

"These pictures were taken at the Rifle Range Trail of the Bukit Timah Nature Reserve.

"The squirrel is a small furry animal that jumps from tree to tree. Last Sunday I saw this squirrel clambering up a rambutan tree and a durian tree.

"It plucked a rambutan and then sat down on a branch with its hind paws grappling the branch.

"With the front paws holding the fruit, it bites into the skin and eats the juicy pulp effortlessly.

"In another picture, you’ll see a half-eaten durian lying on the forest floor. This provided a good meal for the ants.

"Some ripened rambutans dropped onto the forest floor after a shower of rain.

"In another picture is an insect with a black body. Its crimson wings have two saw-tooth antennae.

"The last picture shows a white and brown bracket fungus growing well on dead tree trunks."

The squirrel in the photo is the plantain squirrel (Callosciurus notatus), which is the species most likely to be encountered here in Singapore. It's widespread and common, even in urban housing estates. The stripes on the flanks and the reddish belly distinguish it from all the other squirrel species in Singapore.

Another squirrel species that is quite commonly encountered is the little slender squirrel (Sundasciurus tenuis), around half the size of the plantain squirrel. This species is restricted in its distribution, being found largely in the forested areas of the Central Nature Reserves and Singapore Botanic Gardens.

A relative of the plantain squirrel, the variable squirrel (Callosciurus finlaysoni) is not a native of Singapore, being found in south Vietnam, Cambodia, Laos, Thailand and eastern Myanmar. True to its common name, there is a great deal of geographic variation within this single species; depending on the subspecies and the location, the colours can range from entirely black to reddish-brown to grey to white. Since the early 1990s, a population belonging to the subspecies bocourti from central Thailand has become established in Singapore, largely in the Woodleigh area. It's not known what possible ecological impacts might occur as a result, especially if the squirrel manages to spread to more parts of Singapore.

Singapore's other squirrel species are much more elusive, and rarely if ever spotted. The shrew-faced ground squirrel (Rhinosciurus laticaudatus) is restricted to the forests of the Central Nature Reserves, as are the red-cheeked flying squirrel (Hylopetes spadiceus) and Horsfield's flying squirrel (Iomys horsfieldii). The red-cheeked flying squirrel, known only from Bukit Timah Nature Reserve, was first recorded locally only in 1996.

Unfortunately, the three-striped ground squirrel (Lariscus insignis) is thought to be extinct in Singapore, while the fate of our 2 giants of the squirrel world looks bleak.

The story of the cream-coloured giant squirrel (Ratufa affinis) is especially tragic, considering that the species was first described by Sir Stamford Raffles, and was once quite common throughout Singapore. In fact, it was often caught as a pet or for food up to the late 1960s. Deforestation seems to have been the main cause of the squirrel's decline; it appears that it was eventually restricted to the forests of Bukit Timah and the Central Catchment Area. With a frightfully small population (estimates of the total population in Singapore range from a mere 2 to 10 individuals), it's clear that even if the squirrel hasn't already gone extinct in Singapore (it was last sighted in 1995), it's just about nearly so.

Less is known about the red giant flying squirrel (Petaurista petaurista) in Singapore. This species was last recorded in 1986, so it's possibly already extinct. However, its nocturnal nature and shy habits mean that there is a chance that it still survives in our forests.

Not to be mistaken for a squirrel is the common treeshrew (Tupaia glis), a mammal that's actually much more closely related to primates than rodents.

Similarly, the Malayan colugo (Galeopterus variegatus), another distant primate relative, is not to be mistaken for a flying squirrel.

In a completely unrelated vein, the insect pictured above is a net-winged beetle. Net-winged beetles belong to the family Lycidae, and many species feed on nectar as adults. Most species are brightly coloured in hues of red or orange, signaling that they are toxic and distasteful. They're related to fireflies, among many other beetle families.

Here's a picture of the long-nosed lycid beetle (Porrostoma rhipidius), an Australian species, for comparison.

Tropical fruits galore at Bukit Timah Nature Reserve's mountain biking trail

Tropical fruits galore at Bukit Timah Nature Reserve's mountain biking trail
STOMPer mountain biker was astounded by the array of tropical fruits he saw along the mountain biking trail at Bukit Timah Nature Reserve.

This STOMPer says:

"These pictures were taken at the mountain biking trail at the Bt Timah Nature Reserve.

"While cycling along this jungle trail I stopped several times to look at the fruit trees along the way and snapped these pictures.

"This half-eaten cempedak (Artocarpus champedan) was found on the forest floor. This fruit is native to Malaysia and Thailand.

"The tree grows up to 20m and the fruits are seasonal and barrel-shaped. It is smaller than the jackfruit and when cut, the fruit secretes a sticky latex.

"The outer rind consists of fleshy spines and in each fruit are about 30 seeds which are surrounded with yellow edible flesh.

"The langsat is a small fruit which is green, slowly ripening to a light brown colour. Inside the langsat are 5 segments of juicy white flesh, the flavour being a combination of citrus and sweet. The bark of the tree is used to treat dysentery and scorpion stings.

"The coconut tree grows to a height of 30 m and when ripe the fruit drops to the ground. The unripe fruit is full of sweet water which makes a refreshing drink.

"The rambutans (Nephelium lappaceum) are green slowly turning red when ripe. Rambutans are rich in vitamin C.

"The durian is a popular fruit in Singapore. The animals in the jungle have a constant supply of fruits throughout the year."

All night vigil for free durians at Jln Kampong Chantek

All night vigil for free durians at Jln Kampong Chantek
Foreign workers keep an all night vigil at Jalan Kampong Chantek in order to get free durians, says STOMPer curiousman.

This STOMPer says:

"These pictures were taken at the Durian Loop, off Jln Kampong Chantek.

"June and July is the season when durians ripen and fall.

"Last week as I was trudging through the Durian Loop, I came across some foreign workers who were leaving the forest laden with bags of durians picked from the jungle.

"They had kept a constant vigil by the side of the durian trees during the night and they were amply rewarded with a bountiful harvest of the spiky fruit.

"They came equipped with the necessary gear to stay awake throughout the night. They lit joss sticks and candles to keep the mosquitoes away while they were waiting for the durians to fall.

"To protect themselves from the ferocious mosquitoes they sprayed themselves with insecticide and the can was discarded after use.

"They came laden with newspapers, cigarettes, food, drinks and bottles of beer as they were there waiting for many hours.

"The reward came in the early morning when they harvested the durians which were free."

Canal at Ulu Pandan Park Connector polluted and filled with rubbish

 Canal at Ulu Pandan Park Connector polluted and filled with rubbish
STOMPer shutterbug is alarmed by the state of this canal at Ulu Pandan Park Connector, which is polluted and filled with rubbish.

This STOMPer says:

"These pictures were taken at the Ulu Pandan Park Connector near the Toh Guan Flyover.

"The water in the canal has assumed a rainbow colour, possibly due to the oil and other pollution causing substances discharged by some of the factories nearby. The image of the building is reflected in the water.

"The canal looks filthy with discarded plastic bags, cups, drink cans and other debris. The water here flows into Sungei Pandan."

It's quite ironic that there is a water reclamation plant just nearby that supplies industrial water and NEWater. When will people ever learn that the responsibility of maintaining the cleanliness of our waterways falls upon all of us? We tend to take for granted the fact that the water that flows from our taps is clean enough to drink, but we seem so myopic that we're unable to realise just how irresponsible disposal of rubbish and other wastes can affect our own water supply.

Durian paradise uncovered in Lim Chu Kang

Durian paradise uncovered in Lim Chu Kang
Deep in the greenery of Lim Chu Kang lies a hidden treasure cove for durian lovers, says STOMPer Durian Lover.

The area is always ransacked by durian enthusiasts during June and July every year.

The king of fruits grows on the trees left behind by farmers who used to occupy the land.

Every year, those in the know come to this forested area in Lim Chu Kang to get their hands on some free durian.

STOMPer Durian Lover says:

"These pictures were taken near the end of Lim Chu Kang Road.

"This stretch of Lim Chu Kang Road from Ama Keng Road to the sea was formerly farmland where farmers used to rear poultry and plant fruit trees.

"The land was acquired by the government and the erstwhile farms became uninhabited for many years.

"However these farmers left behind their banana, rambutan and durian trees.

"Come June and July every year, you will see motorcycles, cars and pickups making a beeline for this area as these durian hunters make their annual pilgrimage to Lim Chu Kang in search of their favourite -- the king of fruits.

"They come early in the morning and also in the evening and on weekends they camp overnight to wait for the ripe durians to fall.

"There are no paths in the forests but during the fruit season, you can see several beaten paths created by the pounding of hundreds of human feet.

"These durian lovers would brave all odds, the inclement weather, the attack by snakes, bees and hornets.

"Their love for durians has overpowered their fear of snakes and tarantulas.

"The spiky fruit will always draw a crowd of durian addicts who feel that free durians picked from the forest taste better than those you can buy in the marketplace."

?Green mud crab (Scylla ?paramamosain)
Tanah Merah, 8th February 2009

This was one of many dead and dying mud crabs that were found along a small stretch of canal at Tanah Merah. Nearby, outside the canal, a group of people were happily releasing more live mud crabs into the sea. Some of these mud crabs still had raffia string tied around their pincers and legs, while others were being caught by other visitors with nets and buckets. If only the well-meaning but misguided people could see for themselves the broader consequences of their actions.

Anglers break rules and go fishing at Lake View Promenade

Anglers break rules and go fishing at Lake View Promenade
No fishing is allowed at Lake View Promenade, but nobody seems to care, says STOMPer Fisherman.

In an email to STOMP today (Jul 5), the STOMPer says:

"These pictures were taken at Lake View Promenade beside the Jurong Lake, just opposite the Jurong Country Club.

"The notice says 'SWIMMING, FISHING AND ANY WATER RELATED ACTIVITIES ARE NOT ALLOWED'.

"Last Sunday, when I visited the park I was surprised to see a big crowd of anglers fishing at the pier beside the lake.

"This causes pollution of our waters as these anglers use live baits.

"Perhaps PUB should send its wardens to visit this place on weekends."

Ulu park has trees planted by royalty and famous people

Ulu park has trees planted by royalty and famous people
A STOMPer hopes that more people will visit this godforsaken park which has a rich history where the trees there were planted by famous people.
Historian told STOMP via email today (Jun 4):

"These pictures were taken at Jurong Hill which is a small hill near the Jurong Bird Park.
Ulu park has trees planted by royalty and famous people
"At the end of the road is a small car park and a circular building.

"There was once a bustling restaurant here but now the place looks forlorn and quiet, a far cry from its heyday.
Ulu park has trees planted by royalty and famous people
"Beneath every tree is a ceramic plate which tells you of its rich history as every tree here was once planted by a king, queen, president or a famous politician.

"You see the names of Prince Philip, Duke of Edinburgh, Queen Elizabeth II, former President Ferdinand Marcos of the Philippines and Kukrit Pramoj the 13th Prime Minister of Thailand.

"The place is now quiet, reminiscent of a cemetery even on a weekend.

"Once visited by famous personnel, the hill now lies in a godforsaken corner of Singapore.

"I hope JTC can inject some life into this deserted hill which is a sad reminder of its glorious past."

So many dead fish washed ashore near The Oasis in Kallang

So many dead fish washed ashore near The Oasis in Kallang
The sight of so many dead fish on the shoreline near The Oasis at Kallang surprised STOMPer Ricky. He says that these fish are Tilapia, a species that is normally very resistant to pollution.

Here's what the STOMPer had to say:

"I was watching the sunset today (July 1) at about 7:00 pm near The Oasis in Kallang.

"I spotted so many dead fish washed up along the shore there. This is not normal.

"The fish are Tilapia, which are usually very strong fish that do not die easily. This means that the water must be very polluted in order to kill them.

"I hope the relevant authorities will look into the matter soon."

Birds and droppings everywhere at this once-beautiful park

Birds and droppings everywhere at this once-beautiful park
STOMPer Shutterbug feels that it is a pity this promenade at Queen Elizabeth Walk is overrun with birds and their droppings everywhere.

He says:

"These pictures were taken at the promenade at Queen Elizabeth Walk.

"Once a beautiful park, the beauty of this park has been totally ruined.

"The whole place is now invaded by our winged friends who choose to make this place their unnatural habitat.

"The floor, the benches and the parapets are all stained with bird droppings.

"You see hordes of mynahs, pigeons, crows and other pests.

"A crow with a red eye is a ferocious bird as it attacks children when it is in a bad mood.

"If ever there is a bird flu, this place will be most vulnerable.

"As this place is overrun with birds, perhaps the NParks and NEA could think of ways to reduce the bird population."

Birds and droppings everywhere at this once-beautiful park

While I understand that there might be a need to control bird populations from time to time, it is absolute nonsense to claim that crows with red eyes are "ferocious".

First of all, crows don't have red eyes. Secondly, it's extremely foolish to assume that one can judge the temperament of a bird based on eye colour alone. And how do you tell whether a crow is in a bad mood or not? I'm not quite sure if I follow this person's chain of reasoning. If a crow with red eyes (which to my knowledge, doesn't exist) is in a bad mood (how we can tell, I do not know), it will attack children, and hence, it is considered to be ferocious.

...What?

I admit that urban birds such as the house crow (Corvus splendens), feral pigeon (Columba livia), Javan myna (Acridotheres javanicus), common myna (Acridotheres tristis) and Eurasian tree sparrow (Passer montanus) do not have many fans, even among birdwatchers, and that these birds might possibly have a negative impact on populations of other bird species, but it still doesn't warrant such baseless scare-mongering and exaggeration.

I'm not sure what this person means when he says that this area is an "unnatural habitat" for these birds. Do enlighten us as to what ought to be so-called natural habitat for these birds. As commensal species, these birds are doing so well simply because they have adapted to living alongside us, exploiting the ecological niches we have created in our urban landscapes. In fact, species such as the house crow and Eurasian tree sparrow are so specialised that they are apparently found only close to areas of human activity.

And how ironic that he refers to the birds as "our winged friends" in one sentence near the beginning, and then ends off with a not very subtle hint to cull the birds.

Boatman works hard scooping out rubbish to keep the Singapore River clean

Boatman works hard scooping out rubbish to keep the Singapore River clean
Thanks to this boatman who steers a motor boat up and down a river to scoop up dead leaves and debris, our river is kept clean, says STOMPer Boatman.

In an email to STOMP today (June 30), the STOMPer says:

"These pictures were taken at the Singapore River. The boatman steers a motor boat up and down the river.

"His job is to scoop up the dead leaves and debris to keep our waterways clean.

"As seen in the pictures, there is an orange floater at the mouth of a canal to retain the dead leaves and debris.

"Many dead leaves can be found in our rivers.

"It takes a lot of effort to keep our rivers clean. So next time before you throw your drink can or cigarette box into the river, think of the people who have to clean up the rubbish in the river."

Wood-degrading fungus thrives at Admiralty Park

Wood-degrading fungus thrives at Admiralty Park
The fungi seen in these pictures are known as polypores, says STOMPer Mangrove Man, who wishes to highlight the wood-degrading species to all nature enthusiasts.

The polyporus fungus grows on tree trunks and is commonly spotted on fallen tree trunks.

In an email, STOMPer Mangrove Man says:

"These pictures were taken at Admiralty Park.

"This fungus called the polyporus fungus is leathery, hard and woody. It has no stripes and grows bracket-like on tree trunks.

"The orange polypores are common on fallen tree trunks because of their ability to degrade wood.

"This mangrove tree (Bruguiera cylindrica) can reach a height of 20 m and has buttress roots. The hypocotyl is about 15 cm long, like a green cigarette and slightly curved.

"The trunk of the tree is used for firewood and timber."

Wood-degrading fungus thrives at Admiralty Park

Based on my copy of A Guide to Tropical Fungi, it appears that the fungus in these photos belong to the genus Polyporella, although a bit of Googling suggests that the more accurate name for these bracket fungi may be Pycnoporus instead.


Pycnoporus cinnabarinus, Florida;

There's an error in the description above; it's supposed to be "It has no stipes", which is a different matter from "It has no stripes". The stipe is the stem or stalk-like structure supporting the cap of a mushroom.

Bracket fungi are often found growing on decaying logs, and play an important role in helping to break down rotting wood, and facilitating the recycling of nutrients. However, some species are capable of becoming parasites, infecting living trees and causing the death of their host.

The famous lingzhi (Ganoderma lucidum) used in traditional Chinese medicine is a type of bracket fungus.

It would have been better if the person who submitted this to STOMP had provided a picture of a mangrove hypocotyl and explained what it was as well. I'm sure most of the people who read this post have no idea what a hypocotyl is.

Here's a photo of a bakau putih (Bruguiera cylindrica) propagule. The hypocotyl is the long green part that has already sprouted from the seed.
