Rainy Start but Sunny End to Entomology Walk at Windsor Nature Park

Waking up early in the morning, I was looking forward to my nature walk at Windsor Nature Park, a nature park that I have not yet visited before. Sadly, as I was arriving at the nature park, rain clouds came in and it started to drizzle. In our WhatsApp group, the guides informed us that they have to cancel or reschedule the walk due to the current weather conditions. I was upset that I may have made a wasted trip to the park but thankfully, our experienced guides, Sean and James, informed us that the rain clouds may pass soon and offered to continue the walk if we desired. Whilst most of the group was unable to join us, I and another BFF-er along with Sean and James met up at the park and begin our entomology trail when the rain stopped and the sun came up at 9am.

Whilst many people, including myself, would have thought that after a rain shower, there would be lesser people and fauna at the park, I was pleasantly surprised to see many bees already flying out to collect nectar from the radiant flowers. During our short trail along the Venus Loop, we managed to spot many species of insects including snails, beetles, flies, caterpillars, and many other tiny insects that were just relaxing or moving about on leaves and wood stumps.

Even though the trail was relatively short in distance, we took our time to spot the many tiny insects around us – those that were openly moving on the leaves and fungi-filled stump, those hidden under the leaves and those just actively flying around and “working”.

As someone who never really took the time to observe insects, and at times even afraid of some of them, I managed to learn quite a lot from my experienced guides, who were experts in their own fields of entomology. Thanks to their sharp eyes and extensive knowledge of insects, we were able to find different species of insects at every turn, sometimes even at every step, and I learnt little bits of knowledge about each of the new species of insect that we saw.

I learnt that there were actually many insects who liked to imitate other insects as a form of protection. An example would be a harmless fly pretending to be a dangerous wasp. Ironic how the fly would be bolder than the wasp when we approach it – while the fly will remain still as we edge closer to it, the wasp will fly away at our slightest advancements. Perhaps imitating a dangerous species in the insect kingdom has made these flies bolder and less affected by us humans.

Apart from insects, we also saw other bigger animals such as chickens, plantain squirrels and even a huge wild boar who was just casually crossing the trail and trotting into the forest.

We also saw a few rare insects and habitats on our trail – a huge green tree snail that typically comes out at night, a massive termite mound with thousands and thousands of termites at work, and a natural freshwater habitat inhabited by tiny fish and water bugs.

Overall, I learned a lot from this 3hr walk around the Venus Loop. I learned many new facts about different species and insects and even some tips on how to spot and identify them. One key new fact that I learned from my guides is that there are many species of insects in the world, so much so that they cover half of the animal kingdom that we know, but while there are so many species of insects, there are still so little that we know about them – why they behave in certain manners and even what some species of insects are as many are still unnamed. This is why museums are constantly finding research material from citizens so that they can find out more about the insects we see and hopefully provide better protection and conservation for some of the endangered insects.

This walk started on a low with rainy weather but ended with a high with me leaving with new knowledge and mindsets about insects. Can’t wait for my third and final BFF trip!

1st BFF Field Trip at Sungei Buloh Wetlands Reserve

The last time I visited Sungei Buloh was when I was in primary school. Now, I am in polytechnic and so much has changed at the interesting, wildlife-filled Sungei Buloh Wetland Reserve.

Waking up at 5.30am, I was super tired but I still tried to travel to the wetland reserve with an open mind to learn more about mangrove habitats and I was not disappointed. My experienced guide, Ivan, not only taught us about the various wildlife living in the mangrove habitats but also educated us on many conservation efforts that we can be a part of to help preserve the diminishing mangrove habitats in Singapore. With his keen spotting eyes, we were also able to see many different wildlife flora and fauna in our walk around the reserve.

After meeting up at the Nature Gallery, we proceeded to the Mangrove Boardwalk. En route, we stopped at a small pond where Ivan quickly educated us on the various fish species introduced into the pond. We were then met with a colony of roosting bats on top of a sheltered area.

Be wary of their droppings and do not disturb them in the morning (they need their rest ;))

At the Mangrove Boardwalk, we saw many species of mudskippers, tree-climbing crabs and tiny horseshoe crabs. It was fascinating to learn from Ivan how the mudskippers would dig their “territory burrow” by scooping mud with their mouths then spitting them out in the surrounding area. The end result of this would be a deep burrow with a J-funnel down that will be used in the future for breeding their offspring.

Example of a mudskipper burrow. The mudskippers were seen digging their burrow from beneath the water’s surface by diving into the water then coming out to spit mud out before going back in again.

After completing the boardwalk, we crossed the Main Bridge to the Migratory Bird trail to try our luck at spotting some migratory bird species. Sadly, as the peak season was ending soon, most of the birds have probably already flown north to their breeding grounds but we still managed to spot some herons, egrets and redshanks with the keen eye of our birdwatchers, Ivan and Collin. We were also lucky enough to spot some huge monitor lizards, estuarine crocodiles, including the famous resident crocodile, Tailless, and resident macaques. Nearing the end of our walk, Ivan also shared with us more information about the shore birds that we spotted, their typical travel patterns as well as his own experiences while observing these birds.

While there were many wonderful experiences on the trail, I also witnessed some unfortunate sights. Parts of the mangrove were filled with rubbish that probably washed up during the high tide periods from landfills near Malaysia and Singapore (due to Sungei Buloh’s close distance to the Straits of Johor). As explained by Ivan, mangrove areas are not as easy to clean up as beaches due to land constraints and the community’s own stereotypes about the mangroves (being smelly and a big swamp area), as such, this waste will probably remain in these areas for a long period of time. In addition, erosion sped up by climate change and other environmental factors have also led to certain mangrove plants not being able to get the nutrients that they need. Right now, many mangrove trees are trying to hang on by their last “roots” but if the situation worsens, they may soon “collapse”.

Introduction of new species of wildlife, from the escapee fishes from the nearby fish farms to the common house crows and domestic pets (stray dogs in particular), have led to increased competition in the mangrove habitats as well as diminishing numbers in certain wildlife species found at Sungei Buloh.

Mangroves are slowly diminishing from Singapore due to their inability to adapt to certain areas of water as such, we should do our best to protect our remaining mangroves. While there are many constraints to what we can do, there are also still many other small and simple things we can do. By educating others about the mangroves in Singapore, we can change their perceptions of mangrove habitats and direct them to help conserve these precious habitats. Educating people about the various wildlife species found in these mangroves can also help spark their interest in learning more about mangrove habitats as well as ensure that the flora and fauna there are not disturbed and not taken away from their natural habitat.

To sum up this reflection, I had an enriching and enjoyable nature walk at Sungei Buloh Wetland Reserve with Ivan (our guide), Collin (our BFF-er) and Gavin (our facil). I learned so much and managed to spot so many new wildlife species that I did not know about before. Looking forward to future BFF field trips to come!
