Monthly Roundup: April 2022

While April is usually the month when rarities begin to taper off and most migrants start returning to their breeding grounds for the summer, April this year was anything but quiet!

Highlights

  • At Chek Jawa, a series of likely visitors from Peninsular Malaysia: Large Woodshrike (second confirmed record), Black-winged Flycatcher-shrikeRuby-cheeked Sunbird (eighth confirmed record), Lesser Green Leafbird, and Scarlet-breasted Flowerpecker (second confirmed record)
  • Singapore’s sixth Red Knot, also at Chek Jawa
  • A rather lost Red-necked Phalarope rescued from a pond at Tampines Eco Green, the fifth confirmed record – unfortunately it did not survive overnight
  • One continuing Indian Pond Heron as well as one new record at Lorong Halus, taking the total number of records for the season to three

Our first Monthly Roundup – March 2022

We’ve been getting a lot of great birds lately, all thanks to the enthusiastic contributions of birders in Singapore! More and more members of the community are also using eBird to record their sightings, which has made it easier to keep track of these sightings in a single consolidated source. So we believe now is as good a time as ever for the Singapore Birds Project to start publishing monthly bird roundups, summarizing records of rare and scarce species locally over the past month. This roundup is the first of the series, and it contains sightings posted on eBird as well as rarity records submitted to the Singapore Bird Database.

Highlights

  • First mainland record of Mangrove Blue Flycatcher in over six years, at Pasir Ris Park
  • Fifth national record of Dusky Warbler, at Changi Business Park
  • Two records of Indian Pond Heron; this species now appears to be an annual migrant with multiple records over the last few years
  • A photogenic Oriental Scops Owl at Thomson Nature Park at the start of the month

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!

More ways to interact with Singapore’s rare bird data

Struggling to come up with your next birding destination or your next target bird? Want to find out the best time of year to look for a certain species?

Using past records as a guide is often the best way to make more productive birding journeys, so the team at the Singapore Birds Project has been working on what we hope will be a useful resource to help inform our readers.

Introducing the new, improved Rarities List page, in which we document locally rare species – now with added tables and bar charts which summarize past records. For an example, see the image below.

Clicking the bar chart icon brings up the species chart for Northern Boobook – most records are in early November but a sizable number occur in the spring too… so keep an eye out in the weeks ahead! Clicking on each bar brings up a summary of all the records during that time of the year, and you can click on those rows in the table to view more details on each sighting.

You can also click the table icon next to the species name to show all the records of that species in a tabular format.

Our database now contains over 1400 records and counting – and all this wouldn’t be possible without your support. Thank you, and keep those submissions coming!

Happy Lunar New Year to all those celebrating, and here’s to more megas in the Year of the Tiger!

[UPDATE 10/2/2022] The computational technique used to place individual records in different weeks was modified slightly and the screenshot above was replaced with the newer format.

Singapore Avifauna records on eBird

Five of the 27,000+ records uploaded to eBird from the old Singapore Avifauna newsletters. Photos taken in Singapore and elsewhere (credit: Raghav Narayanswamy and Keita Sin).

For much of my first few years of birding in Singapore, I wondered how the data from earlier eras in local ornithology could be made available for more to benefit; if early dates and late dates, major hotspots, past trends in the local avifauna, among other useful information, could be compiled in an accessible format for the community at large. After all, this small country has always been blessed with a higher-than-average observer coverage relative to its surrounding regions. The data could fill major gaps in understanding Asian avifauna, and be greatly beneficial to interested local birdwatchers as well.

So when I first saw that the Nature Society (Singapore) (NSS) had made its old editions of Singapore Avifauna from 1987 through 2010 available on its website, it was immediately clear that this could be a great resource for the birding community in Singapore if it could be consolidated into a more readily-accessible format. To really know how many times a species has been recorded locally, or which months it appears most frequently, manually scrolling through hundreds of reports for that species would not be practical. Rather, the data would need to be in a spreadsheet, and easily searchable, for the information to be most useful.

Recently, as Keita discussed last week, eBird has established itself as the most widely-used citizen science database for avian records. Many studies have referenced data stored in eBird to examine trends and achieve important conservation outcomes. It also reached a major milestone — 1 billion bird observations — in May this year, reinforcing its position as a powerful tool for conservationists and casual birders alike to share observations and further broaden our collective knowledge. It was clear to me that putting these important records from SINAV on eBird was the best way to make them as impactful as they can possibly be.

In collaboration with Singapore’s eBird reviewer Martin Kennewell, after obtaining permission from NSS to consolidate and upload the records, I set to work on designing a program to extract species names, observation counts, dates, and locations, as well as observer names for proper credit, for all the volumes of Singapore Avifauna available on the NSS website. Dividing this process into two steps: conversion of the PDFs (stored as images) into text, followed by extracting the important details from the text, I was able to upload over 27,000 individual observations, around 23,000 from Singapore and 4,000 from Malaysia and Indonesia.

The records uploaded now make up around 75% of all eBird records until 1990, and over 25% of all records until 2010 (the last year that Singapore Avifauna was published).

I can’t say that this journey was always smooth; one of the biggest challenges I faced was resolving old locations, with old place names, to current landmarks or points on the map which could be uploaded to eBird. With Martin’s expertise and support, I was able to resolve most of these, and sent a further few to NSS for their review. Additionally, some older editions of SINAV were missing; indeed, this was an era with limited technological access and keeping track of documents was admittedly more challenging than it has become today. Older records also suffered from a lack of specific counts; especially as birds that have now become rare once numbered in the dozens or even hundreds, observers sometimes may not have made the effort to accurately count these species.

See, for example, the entry for Sanderling in the report for February 1987.

This species is now barely an annual visitor; in the 80s, 90s, and even the early 21st century, counts in the double digits were regular. It’s hard to believe this count of 100 Sanderlings along with exceptional counts of other shorebirds, was just over 15 years ago.

Sometimes the work was tiring and it became difficult to continue, but I always knew the reward of making all these sightings accessible was worth the effort. In the end, after probably 100 hours of work, I uploaded the data to the NSS Records eBird account.

An example

The excerpts below are from Volume 19 (Jan-Mar) of Singapore Avifauna, published in 2005 (link). I’ve used this example to highlight how the process of digitizing reports into individual records works. For January, February, and March of 2005, Blue-crowned Hanging-Parrots were recorded a total of 12 times. Since the report is split into each of the months, this species appears three times.

These three entries are then converted into text with optical character recognition and combined into one overall entry for the period covered by the report, in this case January to March:

BLUE-CROWNED HANGING-PARROT Loriculus galgulus
1 over Dairy Farm Road, 17/1 (LKS) and 18/1 (LKS) and 4 at Malcolm Park, 30/1 (NK/LKS/FR/IR/JR). At Botanic Gardens, 7 were counted on 4/2 (LKS) and 5 on 28/2 (AF/LKS). Also 3 over Nee Soon, 8/2 (LKS), 1 at MacRitchie Reservoir, 16/2 (LKS) and 28/2 (AF/LKS), and 1 over Dairy Farm Road, 24/2 (LKS). 1 heard at the foot of Bukit Timah, 12/3 (LKS), 1 flying over Dairy Farm Road, 22/3 (LKS) and 3 at Sime Road, 27/3 (LKS).

The individual records are then separated by looking for “sets” comprising the four important pieces of information for each record: count, date, location, and observer names. Of these, the most challenging to parse out is the location. In this case, there’s no extraneous information that we need to ignore, so it seems relatively straightforward to just use the leftover text as the location. But sometimes, sightings are associated with lengthy descriptions and the location needs to be extracted from that description – so I had to use natural language processing to pick out the location.

For the example above, the following 12 sightings would then be uploaded to eBird. This checklist shows how the first record (17 Jan) would appear in eBird’s outputs.

This project is mostly complete, and with it, thousands of bird observations recording hundreds of species have now been placed somewhere they can be accessed by researchers and amateurs alike. As more people come forward to contribute their sightings and share their knowledge, we can make more meaningful progress in conserving our valuable local wildlife.
