A Student’s Big Year

By Kaeden Sim

Twitching and dipping, words I have never heard before. Now, during my Big Year (a personal challenge to see as many species of birds as possible in one calendar year), I would never be more familiar with those two words.

I remember seeing Jen Wei’s Facebook post summarising his epic 2021 Big Year, and being mesmerised by the sheer number of mega rarities all compiled in one photo and to think that they were all seen in a span of one year by one person! It was especially awe-inspiring to personally witness Jen Wei twitching the Yellow-vented Flowerpecker at Bukit Timah summit.

With major exams and other school commitments set to gradually build up over the next few years, I decided that Secondary 1 was a relatively free year to take on the monumental, time-consuming mission of a big year. Nonetheless, the life of a student is still crammed with school related activities, leaving me with much limited time for recreation. Birding only on weekends and holidays practically shortened my ‘big year’ to less than half a year. Every hour spent off the field was truly nerve-wracking – whenever I checked my phone after school, I would be distraught to see reports of rarities, praying that the bird would stay a week for me to twitch. That being said, even if it was challenging, that was what made it so fun.

In the course of the year, among all the lucky finds and successful twitches, two birding encounters made a particularly special impression on me.

It was 18th September and based on trends from data on eBird and SBP, Forest Wagtails would have started passing through Singapore en route to their wintering grounds. However, none were reported recently from the famous wagtail roost at Yishun. An encounter with this elusive bird on Rifle Range Link would otherwise necessitate an ankle-breaking hike at the crack of dawn. Taking a gamble of luck, I decided to head down to Yishun. The wagtails would usually fly in to roost at 6:15, leaving me with 45 minutes to search for the Forest Wagtail before nightfall. I climbed every block, checking each palm tree meticulously. Half an hour passed, and my determination was fading as I routinely scanned through hundreds of commoner Grey Wagtails. At that moment, just as my patience was wearing thin, I noticed a bird that was significantly different. An olive-green and white wagtail with a contrasting triangular black bib on its breast – a Forest Wagtail! Words cannot describe the satisfaction of finding the needle in a haystack, something special hidden within the common birds.

As the year drew to an end, it was naturally becoming increasingly hard to obtain new year birds. Since June, I had been trying sporadically to find the supposed resident pair of Cinnamon-headed Green Pigeons on the west end of Pulau Ubin. Pulau Ubin was one of the most rewarding sites for my year list, with many dispersants and visitors appearing on this small but significant island between Malaysia and main island of Singapore, but yet one of the least accessible and out of the way. Birding at Ubin was always an arduous and tiring task, not to mention the need to pay for a bumboat ride to and from the island, and a taxi to take us to opposite ends of the vast nature sanctuary that it is. With dreadful stories of many failed twitches of these nomadic, unpredictable pigeons, I decided not to give up on this beautiful bird yet, and returned to Ubin one last time in November before I went overseas. Thus, I arranged to bird with my friend Joshua and his brother for an entire day, in the hopes of giving my year list a final push. When we arrived at Changi Ferry Terminal, it was deserted save for two idle fishermen. Our sought-after pigeons were previously sighted in the early hours of the morning and time was of the essence. Out of desperation, my mother decided to pay an extra fee so we could fill the boat and leave early. As the boat set sail, we were off to a good start, having spotted an unexpected Lesser Crested Tern from the boat, trailing a flock of Greater Crested Terns along the coastline at the break of dawn. Stepping foot onto the sleepy island, rain clouds gathered ominously, and we reached Ubin Living Lab just before rain started to pelt down, forcing us to take shelter. We solemnly counted the passing swifts and swallows as we awaited the cessation of the rain. Little did we know, us being grounded by the passing thunderstorm would become a blessing in disguise. Out of the blue, Joshua spotted two Treron pigeons zooming past the shelter. Even before raising my binoculars, I could immediately see the distinct chestnut head and maroon wings of a male Cinnamon-headed Green Pigeon. I was melting on the floor in sheer joy. Later on in the day, we would go on to see a Broad-billed Sandpiper at Chek Jawa, my landmark 300th Singapore lifer, but yet, this pigeon, number 299, stood out to me as special, by far the most memorable experience throughout my entire big year, and it was because of my mother’s support and my friend’s help.

After this, my year list started to plateau, partly due to my travels and the shortage of rarities appearing in December. On 28th December, I found the adult male Blue Rock Thrush at the urban rooftops of The Pinnacle@Duxton – my 284th year bird and the final one of my Big Year. Including ‘plastic birds’, my year count was 300, meaning I managed to see 82.2% of all the species seen over the course of 2022.

As a student, over the course of the year, I learnt how to balance my studies with my hobby effectively. I also realised how connected the birding community is in Singapore, whenever a “star bird” is discovered, the news is always generously shared allowing all to enjoy the presence of it. I have learned so much from the community and have improved my skills significantly, not only in the field, but out of the field, with regards to identifying birds.

Another main difficulty I faced during my Big Year was deciding where to go to maximise my chances of ticking a year bird. Tools that proved to be extremely useful for my Big Year was eBird’s target species function and Singapore Birds Project’s data. eBird allows a simple and easy view of all the year birds I had yet to tick and shows the spots where they have been spotted before, by month. eBird was also very useful in being able to compile my year list and be able to track my progress easily without needing to painstakingly keep my list manually. (eBird is a community science initiative, meaning that this function only works because of the many diligent eBird users submitting their checklists and sightings so I encourage more birders to start using eBird!) Singapore Birds Project’s Singapore Bird Database and Migrant Bar Charts are phenomenal, providing up-to-date information on rarities, allowing better predictions on when and where to go to find certain target species.

I would like to thank all my birding friends especially Jamie, Qian Xun, Pluem, Samuel, Gideon and Joshua for being great company. Secondly, I want to thank Francis, Oliver, Vincent Ng, Keita, Jen Wei, Jared, Raghav and many others for the guidance in the field and amazing finds throughout the year.  Lastly I also would like to thank CN and Benjamin Lee for the advice and tips and congratulate them on their impressive Big Year counts!

However, without the support of my parents, my Big Year count would have been a far cry from what it turned out to be. As the year progressed, my appreciation for my parents grew deeper and deeper. At a moment’s notice, my parents were always ready to rush me down whenever a rarity was spotted. Accompanying me on my birding endeavours, they drove me across the entire Singapore no matter how near or how far. Whenever I was disheartened from an unsuccessful twitch or when I was bursting with pride after a great find, my parents were always there supporting me. My Big Year would not be possible without them and I am forever grateful to be able to have such a thrilling and enriching Big Year with memories that I will cherish for a lifetime.




Year in Review – 2022!

2022 was perhaps an improved year from a Singapore birding perspective – we could enjoy our feathered friends with more comfort compared to the previous two years thanks to the still ongoing incredible efforts to combat the global pandemic. The was a year filled with excitement ranging from the many Himalayan Vultures spilling over from last year, irruption of rarities at Chek Jawa, and a raptor watching season with an abundance of Pied Harriers (including one long staying that offered great photo opportunities) and a more than average numbers of Short-toed Snake-eagles and Besra/Shikra sparrowhawks. Three new species were added to Singapore’s checklist: Black-backed Swamphen (that prompted a review of an older record), Black-headed Ibis and Brown-breasted Flycatcher.

All these records of local rarities are properly documented and curated in our database, and we’re thankful to all of you who have submitted your records. By combining these with other citizen science efforts, this year we’ve also started preparing monthly roundups, accurate bar charts, and various tools to guide everyone’s birding journey. While keeping up with the busy birding scene we’re also glad to have started organising guided walks and booths. Three walks at Bishan-Ang Mo Kio Park, as well as three weeks worth of raptor watching at the Henderson Waves bridge.

More people are showing an interest in biodiversity and many have joined our birding community this year, a trend we’re happy to see. We believe that this energy can be channelled into improving our knowledge on birds as well as into conservation. We hope that the Singapore Birds Project’s works have come in handy and thank all of you for the overwhelming support. See you in the field next year and happy birding!

Singapore Birds Project Raptor Watch at Henderson Waves

The Singapore Birds Project held our first raptor watching booth across three Sundays: 23 October, 30 October and 6 November at Henderson Waves Bridge. We would like to thank all who dropped by and participated in our raptor count – we hope you picked up a tip or two on raptor identification or raptor spotting!

Across the three weekends, we spotted a total of 52 Crested Honey Buzzards, 60 Japanese Sparrowhawks, 29 Chinese Sparrowhawks and resident raptors like the Changeable Hawk-Eagle, White-bellied Sea Eagle and Brahminy Kite. We also snagged a few goodies like a Besra, Eastern Marsh Harrier, Greater Spotted Eagle, Rufous-bellied Eagle, Grey-faced Buzzards and Jerdon’s Bazas. It’s already a great feeling seeing these rare birds, and sharing their directions to a bridge full of enthusiastic birdwatchers makes that even better!

Raptors will still continue to pass through Singapore (in lower numbers) across the migratory season, you can check out our raptoring e-resources on how to identify the birds you see: RAP101: How to Identify Common Raptors, RAP201: How to Identify Uncommon Raptors and RAP301: What is that raptor? You can also check out our bar charts to find out when your favourite raptor peaks or our On This Day function, featuring rarities seen in the day or week. Some raptors you haven’t seen yet might come over the next two weeks or so!

Lastly, we would like to thank Max Khoo for giving us permission to use his raptor identification poster as a resource, the National Parks Board for their support and logistical help, Hui Zhen and Jing Ying for designing the migratory movement poster and our booth guides, Adrian, Cheng Teng, Dillen, Francis, Geraldine, Jing Ying, Keita, Movin, Raghav, Sandra and Zachary for the tireless work across the three weekends. See you all at the next event!

Better Birds, Birders and Birding Through Data (Singapore Edition)


Ask any experienced birder in Singapore about what’s the best and busiest month for birding and you’ll hear either October or November mentioned. After all, migratory birds are coming in fast and furious during this period. One must therefore ask the question, “Are there any studies done to establish whether these two months are indeed the best month for birding?” And if such a study exist, is it October, November or some other months? Now is as good a time as any to have find out.

Before that, let’s have two other interesting questions that are often asked. “Where are the best places for birding?”, “What’s the best time to photograph/observe birds?”. Almost everyone has thoughtful answers for them, based on their own experience and what have been passed on as common wisdom from more experienced birders. It’ll be good if we can get some hard data to confirm these as well.

Birding observation platforms like eBird or iNaturalist may provide some answers to these questions through the sheer amount of data they accumulate from birders over the years. I expect Raghav (our resident data wrangler) to provide some answers and more to these questions sooner or later, using his amazing number crunching skill.

In the meantime, playing the role of a citizen scientist, I am presenting another method here. Not as good, but simpler and tailored for photographers willing to undertake similar projects.

Most photos these days are taken with additional data (metadata) that reveals for example where and when the photo was taken. They also include what sort of camera settings that used to take these photos. When a smartphone is used to take photos, companies like Google and Apple make use of these metadata to customize and remind users of life events like past birthdays and anniversary photos for example (based on date and time encoded in photos), or maybe organize all photos taken on an overseas trip (based on location data encoded in photos) on their virtual album for the users to peruse through.

Using the same type of metadata on bird photos taken using camera gear specialized for that purpose, accumulating enough of them, and cataloging these photos and supplementing these with additional data (when necessary), one can build a mini database of information that allows more definite answers to the questions that were posed at the start of this article.

Methodology (briefly)

The base photos for this particular analysis located in a photo album posted online at https://fyap.net/photos/index/category/singapore-birds

The album contains representative photos of all the Singapore bird species I have photographed and curated over 12 years of bird photography. At the time of analysis, there are 1248 photos over 368 species. To be clear, these are non-random photo selections based on my preferences and birding habits. Photo aesthetics and other technical considerations influenced the final photo set as well.

The program/app called EXIFTool (https://exiftool.org/) is used to extract metadata of all the photos mentioned above and subsequently written to one XML file. The resulting XML file is imported into a database and through some SQL queries, tables and charts are prepared for presentation. The second step can be done in different ways. I am just outlining my general approach. Time and date-centred queries to the raw data from the photos were pared down to 11 full years starting from October 1, 2011 to September 30, 2022. The first year or so of birding wasn’t the most productive nor the most insightful, as lack of experience and a lot of trial and error on the author’s part probably distorted the data in that earlier timeframe.

Full disclosure: There are 5 photos with the wrong EXIF data information due to new camera misconfiguration. These were taken in November 2014 but the EXIF information showed October 2014. Those have been manually reassigned for the graph. The possibility always exist that human error can result in wrong interpretation of data. Luckily these errors were known ahead of time.

Results and analysis (with apologies to serious data scientist)

Best months for birding

A plot of month of the year vs number of photos. Click to see larger chart.

Let’s start with the assumption that bird and birding activity is correlated with the number of bird photographs posted in the album. Extracting and compiling the data on the date in which each photo was taken, we have the chart above.

Mid-year seems to have the least amount of activity locally, as migrant bird species are absent. It is a good time for birders to consider going overseas for birding. Activity start picking up during autumn migration from the north starting from July/August and reach its peak in the month of October. Hence the answer to the first question posed is October.

November and December are still active months for birding, but action tend to slow down in the new year. A modest rise in activity in March can be attributed to peak spring migration. where the migrant birds from the south return up north for their breeding season, passing briefly through Singapore.


Best time of the day for birding

A plot of time of the day vs number of photos. Click to see larger chart.

From the analysis of the time where each photo in the album was taken, we can deduce which hour is the most productive or unproductive for bird photography, and as a proxy, the best time of the day for birding.

The answer, which is from 8am up to 10am is in line with expectation or conventional wisdom. Likewise, there is a distinct lack of birding activity in the afternoon and a slight upturn in activity in the evening from 4pm to 6pm peaking at 5pm.

Due to the restriction in place for access to the nature reserves, nighttime birding is not easy nor productive, and save for some owl species, not worth the effort.


Best sites for birding

This is a screenshot of a web page generated using the same dataset used in the previous two analysis, with the help of a plugin for the photo website called Piwigo-openstreetmap. The URL https://fyap.net/photos/osmmap?/category/singapore-birds&v=1 contain the GPS location of all the bird photos in the album.

Let’s talk about the photos and their GPS coordinates. Some of these photos were encoded with built-in GPS capability in the camera (Canon EOS 7D Mk II, Canon EOS 1DX Mk II), some were from external GPS device attached to the camera (Nikon D500), some were encoded via GPS sent through the camera from the smartphone through connecting app (Sony Alpha 1, Sony Alpha 9, Canon EOS R5). Lastly, for photos taken with older camera models, i.e. photos prior to 2014, manual GPS encoding were done through memory of the places, sometimes with the help of old maps using Google Earth. This does alter the selection of photos, as I may have forgotten the precise location of some older photos and cannot put in the corresponding GPS coordinates. Hence some ‘worthy’ older photos were excluded from the photo album.

From the screenshot, the best site for birding is at the Central Catchment/Bukit Timah/Dairy Farm area. There is a particular bias in the data towards a location at Jelutong Tower, as I spent a lot of time photographing forest birds and migratory raptors at that particular location.

Pulau Ubin, Sungei Buloh/Kranji, Seletar/Punggol/Lorong Halus and Marina East/Southern Ridges areas are also noteworthy hotspots for birding.

Since the dataset is navigable through the website, it is best for those interested in specific data to explore the URL listed above for more information.


Most commonly used shutter speed

Plot of shutter speed settings vs number of photos. Click to see larger chart.

For most parts, the photoset on the website consist of photos taken handheld. Most static photos of birds are taken at the most optimal handheld shutter speed that maximises the chance of good quality photo yet remain as noise-free as possible. A shutter speed between 1/125-1/200s is my preferred option. Hence the peak at that range.

Anything below until 1/30s probably meant the birds were obliging enough, and lower lighting conditions that necessitate a lower shutter speed and consequently less odds of getting sharp photos. At 1/15s and below, shots were taken on a tripod which shutter release cable for low light conditions. Shots taken between approximately 1/250-1/1000s meant a higher probability of active birds, or action shots. The shots taken at 1/2000s and beyond are mainly flight shots.


Most commonly used ISO settings

Plot of ISO settings vs number of photos. Click to see larger chart.

A website that tries to showcase the best representation of local birds would naturally emphasise quality photos over ones that are sub-optimal. Hence the dominance of lower ISO shots especially ISO 100 which is the base ISO for most cameras.

A slight increase at ISO 400-ISO 640 can be explained by the prominence of properly exposed flight shots on sunny days with that ISO range being used.

Although modern camera can give good photos up to ISO 6400 in some cases, bird photography is a special case. This is because while an ISO 6400 shot is acceptable if the bird subject fills the frame with no cropping, the reality is that even at 600mm full frame, most wild birds in Singapore do not fill the frame. In fact, many photos in the album are 100% crop, meaning they are cropped all the way. At such distance and at such extreme crop, high ISO photos are not the best looking. Hence the preference for lower ISO shots.

Context matters in the type of photos selected. Wild bird photos in Singapore are not taken in managed environment (like hides or feeding stations). And in many cases of uncommon or rare birds (which is a focus on the website photos), sometimes there are only a few chances given to photograph the subject. They may be very distant, taken under lower light in uncommon habitat, in the case of rare birds, with many birders squeezed in tight space with limited views, or other sub-optimal conditions.


Camera brands and models used in the photo album

Make/Brand Model Photo Count
Canon Canon EOS 5DS 23
Canon Canon EOS 70D 2
Canon Canon EOS 7D 67
Canon Canon EOS 7D Mark II 29
Canon Canon EOS R5 16
Canon Canon EOS-1D Mark IV 124
Canon Canon EOS-1D X 206
Canon Canon EOS-1D X Mark II 158
SONY ILCE-6400 2

One may be tempted to imagine that there are great insights to be had in looking at a table like the above. One may argue that the Canon brand is pretty dominant in bird photography due to the sheer number of models represented, or that the Sony Alpha 1 is excellent for bird photography due to the fact that on a model basis, it has the highest number of photos on the website.

Such conclusion cannot be justified by this table, because context matters. All cameras are used by only one photographer. Canon is overrepresented because in the past the author used camera for that brand exclusively for the longest time (and still does occasionally). The Sony A1 has the most entries because pre-2014 camera did not have GPS data, and some good photos cannot be posted from those models because the precise location cannot be ascertained. Camera technology have also advanced greatly, hence photos taken in recent years regardless of brands and models are overrepresented because the success rate for ‘good’ photos have greatly increased.

So what else can actually be interpreted from the above table? Well for one, there are too many cameras bought for the relatively small number of photos posted!


It has been fun to dig into the metadata provided by the website/photo album. Most of the results presented here are broadly in line with expectations. A larger dataset would have been helpful to get finer grained results. But we’ll leave that to another day. Hopefully what’s been presented has been insightful to others especially newer birders. Happy birding everyone!

Our second guided walk with the Biodiversity Friends Forum!

Back in Bishan-AMK Park, the Singapore Birds Project held a second guided walk for members of the Biodiversity Friends Forum (BFF).  As part of the Biodiversity Roundtable, BFF aims to provide opportunities for members of the nature community to take action and learn about Singapore’s biodiversity. 

On 22 May 2022, led by Movin, Sandra and Zachary, our group of eager birdwatchers set off. While the walk was not conducted during the migratory season, it provided us with an opportunity to focus on resident birds that we often overlook. Here are some noteworthy sightings on our walk!

The walk started with a flash of colour. A Stork-billed Kingfisher flew past gracefully, before perching out of sight. As Singapore’s largest resident kingfisher, this charismatic bird was an excellent introduction to the wealth of avifauna found in Singapore.

As the Red-breasted and Rose-ringed Parakeets chattered up in the sky, a female Common Flameback flew across our path while uttering its distinctive and rapid call. This woodpecker is commonly seen in parkland habitat, like that of Bishan-AMK Park! Nearer to the waterway, a Purple Heron perched atop a tree. While many may associate the Purple Heron with the consumption of fish, herons are able to swallow small mammals – up to the size of a rabbit – whole. 

The ever-present Black-naped Orioles and Common Ioras impressed participants with their repertoire of vocalisations. Not to be left out,  pairs of Brown-throated Sunbirds and Ashy Tailorbirds chased each other in the trees.

Blue-throated Bee-eaters and Pacific Swallows sallied from their perches to catch unsuspecting insects while a grumpy-looking Pacific Swallow juvenile sat and eagerly awaited its food. When the parent flew close, the juvenile took off, initiating food transfer in mid-air. Acrobatics!

Wrapping up the walk, we observed a Asian Koel as it sat stoically, before getting ferociously attacked by a pair of territorial Malaysian Pied Fantails. Numbers proved to be too much for the koel to handle and it made a tactical retreat. A fantastic spectacle for us, not so much for the poor koel though.

Exploring birds on this day in history

Ever wondered what rare gems were found in Singapore on this day in past years? With the Singapore Birds Project’s new On this day page, you can do just that.

Drawing on our collection of nearly 1,500 records and counting, this page highlights past records on this day in history. As always, every record is accompanied by details and photos where possible.

We hope this will be a valuable resource for birders keen to find megas not seen lately (like this White-throated Rock Thrush, recorded at Bukit Timah Nature Reserve on this day 11 years ago).

And as always, we’re working to develop more similarly useful tools for the community, so stay tuned, and happy birding!

Our first guided walk!

The first of many Singapore Birds Project Guided Walks was held at Bishan-Ang Mo Kio Park (BAMK Park) on 13 and 19 March 2022. Here are some highlights from the walk!

Soon after we set off at 8am, our safely distanced groups came across the most widely-recognized category of feathered friends – chickens! Most chickens found in Singapore are domestic chicken/Red Junglefowl hybrids, and their level of domestic introgression can be estimated by observing traits highlighted in Wu et al. (2020).

Just a few minutes later, a group spotted a Common Flameback up in one of the trees lining the path. As its name suggests, Common Flamebacks are one of the more common woodpeckers found in Singapore and are often heard before they’re seen. Listen out for their raucous ‘kik-kik-kik’ call as they swoop from tree trunk to tree trunk.

The cacophony of loud screams also brought our groups’ attention to the introduced Rose-ringed and Red-breasted Parakeets that have both comfortably made Singapore their additional home. As we were observing them, a White-throated Kingfisher swooped past us in hunt of prey, to the delight of our 6 and 9 year old participants.

The wetland that replaced old concrete canals during the development of BAMK Park has provided some habitat for waterbirds. As we neared one of the main streams running along the length of BAMK Park, our keen-eyed participants spotted some Grey Herons, Purple Herons, a Chinese Pond Heron and two Javan Pond Herons. Herons are frequently found wading in longkangs and wetlands, and use their long, pointy beaks to expertly swipe fish from shallow bodies of water. 

As we continued with our walk, spring was in the air, and we observed many pairs of residents such as the Common Ioras, Black-naped Orioles, Pied Trillers and Yellow-vented Bulbuls moving around in pairs at times, displaying courtship behaviour.

Not to be outdone, the winter migrants like the Pallas’ Grasshopper Warblers were practicing their songs all along the meandering river in preparation to breed when they return to breeding grounds. Close to the end of our walk, we noted a group of fellow birders staking out a section of the river bank hoping to catch a glimpse of the elusive warbler.

Just before we ended our walk, Adrian’s group was treated to an awesome observation up close. A Black-naped Oriole flew onto a tree trunk to pick off a huge caterpillar. The family of 4 were awed by the action happening 1.5 metres in front of them. The Oriole put up an excellent show as it flew up and perched just above the family. It started bashing the caterpillar and before gobbling it up all in view of our young participants and their parents. What a way to conclude an amazing morning!
