Why Count Birds?


Extracts from Lisa Margonelli’s article “When birders with binoculars are better than supercomputers” published in the Sunday Times 31 January 2016. She writes the Small Science column for Zocalo Public Square where she is the science and humanities editor.

As old and personalised as it is, the bird count is a powerful way to collect data and a future model for understanding and responding to environmental issues on Earth-not to mention other planets.”

“The bird count has, at its core, concern about birds going extinct, but over the years that morphed into surprising political power to stop those extinctions.”

” The count also has a secret weapon: It simultaneously gathers needed data and mobilises concerned citizens to advocate on behalf of endangered birds.”

“Obsession makes humans good at finding things because they get distracted by anomalies and their fervour is driven by their emotions. Computers don’t have eureka moments.”

Over the years of counting birds here we have our share of eureka moments. The sighting of a Caspian Tern at Mandai Mudflats during the 2011 Asian Waterbird Census was one of those eureka moments.

In April 1986 the late Clive Briffet, then chairman of the Singapore Branch of the Malayan Nature Society Bird Group initiated and led the very first Annual Bird Census (ABC) here in Singapore. It has been faithfully held every March since with reports published in various scientific journals. It is the longest running census of wild animals conducted by any organisation in South East Asia. Between 1996 and 2005, a total of 33 sites were counted where we recorded 220 species  and 88,596 birds, with 102 species (46%) showing an increase, 66 (30%) showing evidence of decline and 22 (10%) stable. We just completed the 30th ABC on 27th March 2016. Lim Kim Seng will be posting the results soon.

In 1990, members of the Malayan Nature Society (Singapore Branch) joined our fellow Asian member organisations to count waterbirds in our first Asian Waterbird Census (AWC) coordinated by Asian Wetlands Bureau, now known as Wetlands International. Lim Kim Keang coordinated the census for Singapore. This year’s AWC,  the 26th, covering all the mudflats and wetlands was held on 23th January 2016.

Lim Kim Seng, head of the Records Committee initiated the Mid Year Bird Census (MYBC) in 2000 and the Fall Migration Bird Census (FMBC) in 2004 to gather data on the population of our residents and pug the gaps in the diversity of autumn migration. We were able to ascertain that the diversity is just as high as the Spring migration.

With the support from Asian Raptor Research and Conservation Network (ARRCN), we started a full one day Raptors Watch in November 2008 with observers stationed at various locations all over Singapore to count migrating raptors. The count from Singapore help to fill in the missing data on the pattern of the autumn migration of raptors coming down from Malaysia to Indonesia. Over the years we were amazed at the numbers of some of the raptors like the Oriental Honey Buzzards and Black Bazas that passed through our island. It had become a very popular count among keen raptor watchers over the years, thank to Tan Gim Cheong’s efforts after taking over from Alan OwYong.

In 2010, the International Ornithological Union approached the Bird Group of the Nature Society (Singapore) to join in the global count of feral and non native parrots in our urban environment. Thus our latest count, Parrot Count, took flight, under the stewardship of Albert Low, Yong Ding Li and Alan OwYong. The report for our 6th Parrot Count on the 27th February will be published soon.

We will not be able to achieve the success of these censuses and bird counts without the dedicated and passionate members of the Bird Group, friends and the concerned public spending their weekends helping to document the bird life all year round. But we need more to help us to cover more sites. If you are not too familiar with the censuses, come to our workshops and we will brief you on how to count and identify the birds. You will find your eureka moments too.

The Cockatoos of Singapore

Like most urban cities in the world, we have our share of Cockatoo species flying around our parks, gardens and our estates. They are either introduced, released or escaped pet birds. As we do not have any native cockatoo species their impact will be on our native parrots that share the same food sources and nesting sites. So what are the cockatoos that you see flying around your place, where are they from and how are they doing?


A. Tanimbar Corrella C. goffiniana 32 cm is the smallest and the most common of the four species. They are the only ones with a pinkish lore. Established in 1980 (Briffet 1984), they are endemic to the Tanimbar Islands in Indonesia and are classified as globally near-threatened by Birdlife International. Large flocks used to congregate around the Changi Jetty area but now are widespread all over the island. Breeding recorded in our wooded parkland and gardens.

B. Yellow-crested Cockatoo C. sulphurea 33-35 cm is only slightly larger than the Tanimbar Corella They are not common and can be separated from the Tanimbar Corella in the field by its larger yellow crest and dark bill. They also have a yellowish cheek. Residents of Sulawesi, Sumba and Lesser Sundas and are considered globally threatened (BL Int). They were introduced into Singapore with recent records at West Coast and Alexander Parks and Changi Point. Surprisingly we do not have any breeding record.

C. Sulphur-crested Cockoo C. galerita 50 cm is a large noisy cockatoo. More common than the Yellow-crested, they lacked the yellowish cheek but has a blue eyering. They are native to New Guinea and Australia brought over as pet birds. Mainly escapees, there is a fairly large population in Sentosa, Southern Ridges and Loyang. We do not have any breeding records.

D. Salmon-crested Cockatoo C. moluccensis 50 cm was once fairly common but seem to disappeared. Their crest is dark pink from where it gets its name.  Its range includes Moluccan Islands, Seram and Ambon. Like the Sulphur-crested, they are escapees and are found mostly in Sentosa. They are considered as globally threatened (BL Intl). We have yet to have a breeding record here.

While their numbers are threatened and in decline in this native ranges due to poaching, their population in bird parks, private collection and free roaming in our urban spaces are stable enough to ensure their long term survival. Every year in February, the Bird Group conducts a Parrot Count to document the trend of all the parrot species including these cockatoos in Singapore. If you come across roosting sites of our parrots and these cockatoos, please drop us a note but better still help us with the count.
