Seen@: Weaver Ants!

The weaver ant gets its name from literally weaving their nests out of leaves, using silk from the young ant larvae (or, as Moffet jokes, using child labour). A good way of identifying these nests is to look for anything from an opaque leaf folded into itself, to a oblong-shaped collection of leaves with white silk holding it together along the seams. The creamy larvae is also considered an important source of protein-rich food for communities that harvest them.



These ants are highly territorial, and do not hesitate to spit formic acid into their bites, so take care not to come in contact with their trial! Don’t worry - formic acid isn’t toxic, unlike the venom from fire ants. It actually has antibacterial properties, and the ants have been harvested and crushed to be used in traditional medicine. (Formic acid also contributes to the weird smell of a crushed ant.)


They are also mimicked by (aptly named) spiders - the ant-mimic jumping spider and the ant-mimic crab spider - and a caterpillar. This mimicry allows the spiders to hunt weaver ants in close proximity without being suspected, and provides protection to the latter.

In case you haven’t noticed, the weaver ants in school have been around for a while - they nest among the vertical greenery on the sixth and seventh levels, and travel between Block A and B via the string of bamboo segments. Yes, you have been walking under them all this time! Here’s the fun part: traditionally, Chinese farmers used them as ‘live pesticide’ to eliminate pests in fruit trees, and encouraged the colony to migrate and expand by placing bamboo poles between the trees. (And we have done that unintentionally.)


Their nests are highlighted in red above!


Hope you’ve enjoyed learning about these interesting critters - here are a couple of links where you can learn more about them in detail, as well as where we got our information from:

Seen@: Olive-backed Sunbird (Nectarina Jugularis)

You’ve probably seen them around – these birds resemble hummingbirds and can often be seen feeding on nectar of the morning glories blooming all around school.  The olive-backed sunbird can be identified through (obviously) having an olive back and yellow belly – the males are more rarely spotted and have a metallic blue chest.


This tiny bird has adapted from its mangrove home to building nests near, and in our concrete jungle. (Here you see a pair of sunbirds perched on a chandelier.)


It’s understandable how people mistake sunbirds for hummingbirds, as they are physically similar, but here is a funfact: there are no hummingbirds in Singapore!
The sunbirds mate between April and August, so if they do nest at or near your home, let them be! If you’re lucky, you might be able to observe their mating dance, where males show off tufts of saffron feathers at their throat. To photography enthusiasts: try to take photos or videos of them form a distance zooming in. Getting up close may be invasive and disruptive to nesting birds!


If you would like to find out more about this species, we recommend you to check out the Sungei Buloh Wetlands website (here).
p.s. Sungei Buloh is also reportedly a good place for sunbird watching!
p.s.s. here’s how the sunbird sounds like:

Save That Pen: Pendamonium Installation on 5th April 2014 (More updates coming soon)



After 2 months of hard work, commitment and problem solving, the Green Beans STP team has finally installed our installation (Pendamonium) on 5th April for Save That Pen Day. This installation is constructed from hundreds of used, non-functioning pens collected by Save That Pen, an organization that refills and donates these unwanted pens to underprivileged children.

During the day, many visitors interacted with the chromatic curtain of pens and were (literally) hit by the sheer scale of waste. It was indeed heartening to hear unique yet valid interpretations of our installation during a feedback survey conducted by our group members. For instance, one participant commented that she felt that the installation was an apt representation of "the unity" in the various schools present to save their pens.

On the whole, we would like to thank Save That Pen for the opportunity and the memorable experiences we have gained from the project!

Have the Beans been to Ubin?


The Green Beans went for our 7th Ubin trip yesterday, and despite being initially disappointed that out of 50 Green Bean members only 3 had come along with us, we enjoyed the walk so much and even had NMP (Or Almira’s Mom haha) Ms Faizah join us for a short while together with Andy, an experienced birdwatcher. The small group enabled a much better dynamic and facilitations, and with 5 people altogether, we also got to know our Year 5 Beans better. Furthermore, we will be having another Ubin walk next week, with Vanessa, XiaoLi and Monisha guiding the group.

The day started out with the sight of a Falcon enjoying it’s meal; a pigeon! Our surprise when we stepped onto the Island and met Andy, an experienced birdwatcher who immediately pointed out the scene and even gave us to opportunity to see it close up with his telescope. What an amazing experience (albeit slightly disturbing one), especially when the poor pigeon’s feathers began falling down from the tower onto the spot we were in.
The scene of the bird gore on the tower, and here we see the video of the Falcon enjoying its meal being capture on an iPhone

Going to Pekan Quarry and then Butterfly Hill, we saw loads of egrets and learnt about the various types of egrets that we do have in Singapore. Along the way we had the chance to see a artificial hornbill mating box, purposefully attached to a tree by NParks. Once having 3 recorded species of Hornbills in Singapore, the Rhinoceros Hornbill, the Helmeted Hornbill and the Oriental Pied Hornbill, the population has been narrowed down to merely the Oriental Pied, as the Rhinoceros and Helmeted Hornbill went extinct before the 1900s and in the 1950s respectively.
Made to encourage hornbills to mate, so as to increase the population of the Oriental Pied which was once believed to be extinct, the artificial nests has come with much success and over 100 Hornbills now reside in Singapore. However which the increasing population of Hornbills comes the question of what its impact is, and many believe that the rapid increase of Hornbills in comparison to other groups of birds in Singapore (that may be more endangered) may actually be more detrimental than beneficial.

The ecological system is definitely one of an extremely complex nature, and every single fluctuation within in will definitely introduce impacts onto the rest of the system. And this also reflect the various global environmental issues; as with the Palm Oil Industry in Sumatra. While some may choose to blame the Palm Oil Industry for all their negative impacts of the Indonesian forest, one cannot ignore the fact that Palm Oil is essential to their economy. The environment and economy are intrinsically linked, and having a more holistic view of environmental issues allows us to comprehensively understand the larger framework, so as to make better judgements and opinions. Every single thing will affect another, and that’s what casts such importance upon maintaining this delicate balance between everything, whether it be the economy and environment, or the hornbills and other birds. And this is where we come in, to play our own roles as members of this Earth!
At the Butterfly Park, we saw so many different butterflies (none of which we could identify haha), and learnt about the different flowers and fruit we saw along the way. One of them was the Torch Ginger, and if you’re Singaporean you should definitely know this for being in our Rojaks! Another was the Fig Tree, which we learnt is pollinated by wasps. Unfortunately the Fig trees in Singapore apparently either don’t taste too good or are inedible.
 
 
After that we parted ways with Ms Faizah and Andy, and headed off to Chek Jawa! Wild Boars as usual came around the corner and of course, the cameras came out.
 
The Fish-tail palm (Caryota), it’s jagged edges makes it appear as though it’s been eaten already, warding of potential predators.
The Vinegar Crab, also known as the tree climbing crab. With the ability to climb up to 6 meters high on trees, it’s also more famously known to be pickled and eaten with black sauce and vinegar in porridge.
The Attap tree, also known as the Nypa Palm. Known for being in South East Asian desserts (that terrible tasting thing everyone avoids).
Mangrove Roots are specially adapted to survive in the soft, loose soils through structural adaptations that allow them to keep upright and standing. There is so much more to Mangroves, such the the ability of their leaves to control their stomata, as to conserve freshwater; vital in a saline environment. Some species have the ability to retain salt in their leaves, and discard them when content gets too high. Even the way they reproduce is amazing! Seed grow until they reach a stage where they become large, long and cylindrical. It is then dropped into the soil, and over time grows to resemble pencil-like roots, before becoming a full-grown adult tree.

A short break for the Beans.

When we got back to the visitor centre at Chek Jawa, we witnessed some people feeing the Wild Boars. The Boars began to get excited and started to fight over the bit of bread these people were handing out. We asked them to stop, and when the people stopped feeding them and walked away, the Boars started to follow them around. Highlighting the dangers of such actions, feeding animals in Nature Reserves is definitely not a very smart thing to do, and it’s important to consider the ethical implications of one’s actions, not just doing as we please.

Ended the day with the ride back to mainland, and Lontong and Ice Kacang!
