From the lens of a rookie birdwatcher

A few months ago, Lim Kim Chuah, Chairperson of the Bird Group was asked to conduct a test for girl guides who aspire to have the Birdwatcher Badge. He took a student from MGS, Hao Yunrui under his wings, went over to her school one afternoon, pass her a pair of binoculars and also one of our field guide written by Ding Li and et al. He showed her the birds in her school, taught her a few things about birding and then gave her some assignments. The assignments were: 1) learn and write her observation on 6 species of birds that she can find in her school or around her home/park 2) to participate in one NSS Birdwatching activity 3) to write a reflection on her journey
Here is Hao Yunrui’s reflection:

After an eventful few weeks of dabbing into amateur bird watching, I’ve gathered some thoughts to share about this fascinating hobby. When I initially made the decision to take on the Bird watching Badge, I saw it as something to be done and then simply forgotten. Like ticking off the goods on the grocery list, it was just one of those things that I needed to try out once to clear it off my bucket list. Mrs Tham then brought me under the guidance of Mr Lim Kim Chuah, who then carried me through the course of my one month Bird watching Journey. His tasks for me were:

First, to make a bird watching journal covering my observations of 6 different species of birds

Second, to go on a Bird watching trip with the Bird Group members of Nature Society (Singapore).

Hmmm, that sounded easy, was what I thought to myself when I first saw the tasks assigned to me, and that marked the start of my fascinating journey of unveiling a new realm of experience whose door had previously never been opened to me.

To achieve the tasks, I made it a point to go to various nature reserves and parks to watch birds every Saturday. My aim on each of my solo trip was to spot at least one species of bird that is new to me (a lifer in birdwatchers lingo). I also jotted down my observations in a field logbook (which would later become my bird watching journal) and if those tiny flickering feathered friends would allow me, I would try to snap a picture or two.

During my early morning sojourns to our parks and gardens, I spotted a variety of birds some of which made calls which I have heard previously e.g. the Asian Koel. It dawned on me that all of us do cross paths with many types of birds in our daily life. We hear their calls, catch their silhouettes among the trees but we are usually so caught up with our busy schedule that we choose to ignore such beautiful creatures in our midst. Throughout this one month, I sometimes wonder, if only people could spare a moment to look at the flowers and trees around them instead of staring into their phones. Only then will they discover the feathered wonders among our midst – those eye-catching and bright yellow Black-naped Oriole and the ubiquitous loud and noisy Asian Koel. And if you care to look closely at the Eurasian Tree Sparrow, you will realise that the patterns on its back are actually intricately beautiful. If you observe a Javan Myna, it is not all black but has white patches on its wings when it flies. These are some of tiny details that many of us fail to notice but which is really visible if we could only spend some time to observe them. On the hindsight, I was also like one of these people. I am glad taking on this bird watching badge has taught me to be more observant of the nature around us.

Through this experience, I have managed to see a lot of rare and interesting birds. Mr Lim took the extra step to encourage me to join the Nature Society on a birding walk to Kranji marsh. It was really an eye-opener and a wonderful experience which will certainly open up my eyes and taught me to see our natural world especially our avian friends through a different set of lens.

These are some of the shots I’ve captured over the weeks. However, I wasn’t able to capture most of the birds that I saw as they were either too far away or flying. The graceful physiques of these birds were instead captured by my eyes with binoculars.

The trip to Kranji Marshland was really eye-opening ( quite literally ). It’s the first time I am visiting a marshland. And I felt privileged to be able to visit the core area of this park which is yet to be opened to the public. I initially felt really awkward and out of place because everyone else around me were equipped with gigantic, state-of-the-art bird viewing equipment and most participants were in their 40s and 50s. However, it was evident that they were really passionate about what they were doing as they could call out the names of all the birds that came within our view. Some could even spot birds miles away with their sharp eyes and telescopes were also on hand to allow close views of distant birds. It was quite heartening to see a handful of young adults mixing in the crowd because it truly shows that this hobby is not just for the “old” but the young as well. It was the first time I ever felt so close and intimate with nature, as though I were a part of it and it a part of me. Watching our feathered friends in such a quiet place gave me a sense of connection. When the White-bellied Sea Eagle stared intensely into my eyes through the binoculars, I could almost feel it whispering to me. Seeing nature fully at work was very magical, because everything seemed to be in such perfect balance without the interference of man. We spotted a Purple Heron poking its head out of the water hyacinths in search of prey. It made me realised that nature can function by itself perfectly and does not need our help to survive, but rather we are the ones who constantly seek help from nature. We should treasure of whatever nature we have conserve it to the best of our ability.

Bird watching is no longer something to be simply tick off my bucket list. I hope to be able to visit such places again and be acquainted with its many fascinating birds.

My thanks to Mr. Lim Kim Chuah for his guidance, time and sharing his knowledge with me, Mr. Wong Chung Cheong and members of the Bird Group for showing me the birds at Kranji Marshes.

Singapore Raptor Report – Late Spring Migration, April-June 2016

WBSE, 210616, Sentosa, James Tann

A rare photo of an adult and a young White-bellied Sea Eagle “cartwheeling” over Sentosa, 21 Jun 16, by James Tann.

Summary:

On 21st June, James Tann captured a rare series of photos of two talon-locked White-bellied Sea Eagles ‘cartwheeling’ through the air over Sentosa. Some books described this as ‘talon-grappling’ and ‘tumbling’. Interestingly, an adult and a young eagle was involved in this instance whereas this behaviour is usually attributed to mated pairs but only mature adults have been known to form breeding pairs.

Now, for the migrants. Five migrant raptor species were recorded in the April to June period. Four of them – the Osprey, Oriental Honey-buzzard, Japanese Sparrowhawk and Peregrine Falcon were also recorded during last year’s late spring migration. The notable addition this year was the Rufous-bellied Eagle: a juvenile was photographed at Lorong Sesuai on 23 April enjoying a meal.

Of the 14 orientalis  Oriental Honey Buzzards recorded, 11 were juveniles (there were 10 in the same period last year), one was an adult female while the remaining two were not aged. Most of the juveniles were moulting their flight feathers (most were showing new P1 & P2, counting from the inside). It is worth mentioning again that juveniles are known to ‘over-summer’ in the tropics.

Only one Japanese Sparrowhawk, an adult female, was recorded on 2nd April. Two Ospreys were recorded at Sungei Buloh Wetland Reserve in Apr and May, but none in June; elsewhere, there was a record at Singapore Quarry in Apr and another record at Seletar Dam in May.

Two Peregrine Falcons were recorded in April – one at Pulau Ubin on 8th and another at Chinatown on 21st. An ernesti Peregrine Falcon returned to its usual haunt at the rooftop of buildings at Church Street on 26 May and a juvenile, likely also ernesti, flew over Punggol Barat on 15 June.

Back to the resident raptors. The usually encountered resident raptors were all present. Notable records included the locally rare Crested Serpent Eagle which was recorded thrice in April (Kent Ridge Park, Ubin & Bidadari), twice in May (Sungei Tengah & Malcolm Road), and once in June (Chancery Lane).

Also, April to June was a good quarter for the Crested Goshawks – in April, two juveniles were photographed at the leafy compounds of the Singapore Zoo and an adult male was seen collecting twigs at the Southern Ridges where two nest structures were seen; in May, the species was recorded at the Botanic Gardens and Bishan; and in June, a total of four juveniles from two different nests were recorded at the Botanic Gardens.

Many thanks to everyone for sending in / sharing their records; and to  James Tann for the use of his photo.

Green Coffee Tree

On 30th May, Wendy Lin and her friends went to Seletar Reservoir Park to look for the uncommon  Chestnut-winged Babblers, Stachyris erythroptera, that Francis Yap shot days earlier. They did not see the Babblers but came across the Red-crowned Barbets  Magalaima rafflesii, feeding on large green berries on a tree by the roadside. The tree was identified by Albert Low as the Green Coffee Tree, Canthium glabrum . It is a native in Singapore and classified as endangered. The fruit is round to oval, green to dark purple when ripe but described in NParks Flora and Fauna Web as 4-ridged shape between 2.5 to 3.2 cm. There are two seeds in each fruit.

Red Crowned Barbet Terence Tan

The Red-crowned Barbet was observed by Lim Kim Keang to squeeze the ripe fruit and eat the pulp, They will also swallow the fruit and later regurgitate and swallow  the fruit repeatedly  to get all the pulp.

The Red-crowned Barbet is an uncommon breeding resident confined to our central forests. They are hard to see at the Sime Forest nowadays but can be heard calling from the tree canopies in the mornings. So when word got out that they are feeding there, Selatar Reservoir Park became the latest hot spot for our birders and photographers. The fruits were enough to keep them coming back for more than a month.

And like all fruit trees they invariably attract other frugivores like the Common Hill Mynas, Orange-breasted Flowerpeckers, Pink-necked Green Pigeons, Olive-winged and Cream-vented Bulbuls. Even the non breeding Jambu Friut-Dove was seen partaking the feast. A Blue-winged Leafbird was also photographed there but it maybe looking for worms that are eating the ripened fruits.

Palm King

Besides birds the forest butterflies can be seen first feeding on the ripe fruits on the ground and later flying around the fruits on the tree. A Common Palm King was busy taking in the juices from the ripe fruits. Sailors and Lascars  joined in the feast. Other species seen by Kim Keang flying around the tree were Saturn, Malay Viscount and female Barons.

The surprise was that the Long-tailed Macaques were not the least interested in these fruits. The only mammals seen eating them were the ever present Plantain Squirrels. This would be a good plant to propagate to attract birds and butterflies and increase the biodiversity in our parks and gardens.

Singapore Bird Report-June 2016

Blue-eared Kingfisher Mark Nelson Valino

There were less excitement this month compared to last June. Then we had the first record of a White-tailed Tropicbird at Tuas, an Oriental Darter at Ubin and the wintering Horsfield’s Bronze Cuckoos at Punggol Barat to keep us busy. This June, we had to be contented with the King Quails, Excalfactoria chinensis, at Punggol Barat, Blue-eared Kingfishers, Alcedo meninting, at Kranji Marshes and Red-crowned Barbets, Megalaima rafflesii at Seletar to keep our shutters clicking. On the plus side we had many interesting nesting records including a first from all over the island.

Red Crowned Barbet Wendy Lin

Wendy Lin and friends Peter Okimi, Chai Lee Fung and Edwin Choy were at Seletar Revervoir Park on 30th May looking for the Chestnut-winged Babblers when they chanced upon the Red-crowned Barbets feeding on the fruits of the Green Coffee Tree. Photo: Wendy Lin showing the barbet squeezing the pulp out of the fruit.

The most surprising record came from Cashew area on 20th when a member of the public reported a baby owl at the foot of a rain tree on her way to work. NParks staff rescued the owlet and subsequently put it back into its Bird-nest Fern nest much to the relief of a pair of Spotted Wood Owl, Strix seloputo, parents. This is a rare nesting record for this uncommon owl and confirmed that they also use Bird-nest Ferns to nest just like the Buffy Fish Owls.

There were several important nesting records from Ubin. A pair of Stork-billed Kingfisher, Pelargopsis capensis was found nesting in an old termite nest on 4th. The nest was attached to a bamboo (Lim Kim Chuah). This could be the first confirmed nesting of this kingfisher in Singapore. A failed nesting of the Mangrove Pittas, Pitta megarhyncha, there, probably due to predation; and the nesting of the most common bird in Ubin the Olive-winged Bulbul, Pycnonotus plumosus, (12th Lim Kim Keang). Elsewhere another failed nesting of the Pied Triller, Lalage nigra, at Punggol Point on 15th (Seng Alvin); two Crested Goshawks, Accipiter trivirgatus, fledged at Singapore Botanic Gardens on 18th (Laurence Eu); Sunda Pygmy Woodpecker, Dendrocopus moluccensis, at Taman Jurong; Pacific Swallows, Hirundo tahitica, at Stagmont Park on 21st (Timothy Chua) and the Blue-throated Bee-eaters, Merops viridis, at Punggol end.

Winter visitors recorded for the month include a Greater Crested Tern, Thalasseus bergii, photographed off Pulau Pawai by Francis Yap and his friends during a mini pelagic trip to Raffles Lighthouse on 25th. This is a new extreme date (previous late date: 18 June 1990). Another winter visitor still present was the Blue-winged Pitta, Pitta moluccensis. At least three were heard calling at the edge of the Western Catchment on the 19th (Alfred Chia). Will they spend the summer and even breed here? Time will tell. Egrets are known to over summer in our wetlands. All three species were recorded this month. Intermediate at Lorong Halus (Lim Kim Keang), Little and Great at SBWR (Lim Kim Seng) all on the 12th.

Great crested tern FYap

We know that the second calendar year Oriental Honey Buzzards, Pernis ptilorhynchus, stay over during summer and do not migrate back north. Two were photographed, on 11th over SBTB by Andrew Tan and the other at Ubin by Lim Kim Chuah on 12th. Both were juveniles. A dead Black Bittern, Dupetor flavicollis at Aljunied Avenue on 10th was picked up by David Tan.

Peregrine Falcon LTK

Resident ernesti race Peregrine Falcon flying over Punggol Barat captured by Lee Tiah Khee.

Other notable sightings were three Black-naped Terns, Sterna sumatrana, flying across Keppel Harbour on 8th (Richard White) and three more near the southern island of Pulau Senang on 25th (Francis Yap). These resident terns were more common in the northern straits where they have been nesting at a rocky out crop since 1949.. Francis also recorded ten Pied Imperial Pigeons, Ducula bicolor, flying pass Pulau Sudong on the same day. These are the wild pigeons that spend most of their time around the southern islands. A Buffy Fish Owl, Ketupa ketupa, was photographed at Hindhede Quarry by Raghav Narayanswany on 19th confirming the further spreading of this uncommon owl. A second in two months of a resident ernesti race Peregrine Falcon, Falco peregrinus  was photographed by Lee Tiah Khee on 15th over Punggol Barat. The locally rare Crested Serpent Eagle, Spilornis cheela, was photographed by Jan Roberts on the 4th at Chancery Lane.

Seng Alvin reported three to four Plaintive Cuckoos, Cocomantis merulinus, at Pasir Ris Park on 3rd. Could be that foster parents like the Malaysian Pied Fantails are plentiful there? The on-off Black Hornbill, Anthracoceros malayanus was seen flying around the Pekan Quarry at Ubin on the 4th (Lim Kim Chuah). It is still listed under Category E for suspected escapees and released birds.  The introduced Javan Munias, Lonchura leucogastroides were back at SBWR on 7th (How Sung Lee).

Over at the Hindhede Park, mother and son team, Subha and Raghav Narayanswany sent in records of Black-crested, Pycnonotus flaviventris, and Asian Red-eyed Bulbuls, Pycnonotus brunneus, Blue-winged Leafbird, Chloropsis cochinchinensis and a pair of Jambu Fruit Doves, Ptilinopus jambu feeding on a fruit tree. Due to the closure of Bukit Timah Nature Reserve, Hindhede Nature Park was also hardly visited. This may account for the increased bird activity there.

INTRODUCTION

On 5 June 2016, the Nature Society (Singapore) Bird Group conducted a survey to find out which were the commonest bird species on Pulau Ubin. This survey was organized in conjunction with the month-long Pesta Ubin 2016 event. The Bird Group has been birding on Pulau Ubin since the 1970’s and 80’s and this survey to determine the commonest bird species on Pulau Ubin was also timely.

METHOD

A total of six teams consisting of six leaders and six participants took part in the CBQ. Areas in the central and eastern part of Pulau Ubin were covered. The routes were carefully selected to cover as much of the island as possible within the allocated time from 8.00 to 10.00 am. The good weather helped and most teams completed their designated route in the allocated time except two which went on overtime.

The MacKinnon bird listing method was used to determine the commonest birds on Pulau Ubin. This method involved recording each new species of birds (seen or heard) until a pre-defined number of species is reached. Once this pre-defined number is reached, a new list is started. Any one species will only be recorded once in the first list but may be recorded again in subsequent lists. For our purpose, we decided counting up to 10 species before starting on a new list.

The relative abundance of each species is calculated by dividing the number of contacts by the maximum total number of contacts by all teams  (i.e. total number of lists).  A bird which is more common will have a higher relative abundance index than one which is less common.

RESULTS & DISCUSSION

Table 1 shows the top 20 commonest birds based on the relative abundance indices.

9 Olive-backed Sunbird 18 0.35 19 Asian Glossy Starling 12 0.24
10 Dark-necked Tailorbird 18 0.35 20 Ashy Tailorbird 11 0.22
Olive-winged Bulbul

Olive-winged Bulbul is Ubin’s most abundant species.

The survey by the six teams produced a total of 51 lists. The relative abundance index of the birds detected ranged from 0.02 to 0.65. A total of 63 species were recorded during the CBQ. The most abundant species is the Olive-winged Bulbul. It recorded the highest relative abundance index of 0.65 and was recorded in all the surveyed sites. This is interesting as other censuses conducted by the Bird Group have consistently found the Yellow-vented Bulbul to be the more common bird in most parts of Singapore. The habitat on Pulau Ubin which consists of a mosaic of orchards, old rubber plantations and secondary forest probably contributed to this result.

Another interesting point is that more species were recorded in the  central routes than the eastern ones. It is possible that the more wooded nature and closed canopy along the eastern routes could have resulted in less birds been detected.

A very significant observation from the survey is the relative abundance of both the Straw-headed Bulbul and White-rumped Shama. Both species are becoming scarce in many parts of Southeast Asia as a result of rampant trapping for the bird trade. It is critical that the authorities and the public remain vigilant against potential poaching here and other parts of Singapore where these species are thriving. If the current situation persists, Singapore could become the only place in the world where these species survive in the wild.

As in all rapid survey and census, it is inevitable that biases exist. The most obvious bias is that this is a rapid one day count lasting only 2 to 2.5 hours. It is conducted at a time where some species may be more vocal than others and most if not all migrants are absent. Another issue involves the detection bias towards species that are more vocal or active at the edges of habitats as the selected routes were along existing roads, trails or boardwalks. But in general this survey does provide a fairly good picture of which are that common resident birds that you can expect to see on a bird walk on the island in the middle of the year.

COMMENTS

The Pesta Ubin Commonest Birds Quest provided an opportunity to involve and encourage the public to participate in a citizen science project. The data collected over an extended duration could be used to monitor changes to the avifauna of Pulau Ubin and ultimately the state of the environment here. A common bird today may become very rare or even become extinct tomorrow if its habitat is altered irreversibly or destroyed. One example is the House Swift which is no longer a common species. House Swifts used to build nests under the Pulau Ubin Jetty but have been absent for many years. Are the proliferation of swiftlet houses and the hordes of swiftlets the cause of decline? Or are there more serious environmental problems?

Nesting Pacific Swallows at a Housing Estate

Nesting of Pacific Swallows in a Housing Estate.

Contributed by Timothy Chua Jia Yao.

On the 21st of June, I came across a untidy nest built on the protruding sanitation pipes under a block of flats at Stagmont Park.

Pacific Swallows 3 Timothy Chua

The nest was made with dry leaves, grasses and fibers bind together with mud.

Pacific Swallows Timothy Chua

There were three chicks in the nest belonging to a pair of Pacific Swallows, Hrundo tahitica, a very common resident in Singapore.

They looked to have hatched about a week ago. The residents there told me that they have been using this site for the past few years.

This tally with the nesting report in The Avifauna of Singapore (Lim Kim Seng 2009) of a pair of Pacific Swallows using the same site at void deck at Woodlands for five years

Alan OwYong told me that we do not get many nesting records here and that I should monitor the nesting.

When I went back to check on them on the next day only one chick was in the nest. The other had fledged and was on the ground near to the nest.The parent was looking after and feeding it.

The remaining chick fledged last Sunday 26th. I also found the third chick on the floor below the nest, dead. It may have dropped out of the nest or maybe pushed out by its siblings before it can fly. Two out of three is not bad. Within days of fledgling, the family was not around anymore. The chicks must have grown up fast and learn to fend for themselves early, an instinctive survival strategy against would be predators.
