The 35th Annual Bird Census (ABC) was conducted on 29th March 2020 just before the nation-wide “circuit breaker” kicked in. Organized by the NSS Bird Group, it saw the involvement of 39 members and volunteers at 26 sites all around Singapore. This is an improvement from last year when 39 counters covered 20 sites. Altogether, ABC 2020 logged a total of 6,342 birds and 147 species, an overall increase from 2019’s 5,496 birds and 143 species. This could be due to more sites been counted in 2020 as compared to 2019.
So what’s Singapore most abundant bird? If you are guessing Javan Myna, you’re wrong! It is the Asian Glossy Starling which scored 847 birds to beat Javan Myna, with 737 birds, into second place. Third was Pink-necked Green Pigeon (358), followed by a resurgent House Crow (256) and Yellow-vented Bulbul (250). The rest of the Top Ten species are Little Egret (186), Common Redshank (170), Black-naped Oriole (164), Spotted Dove (152) and the nationally threatened Grey Heron (149).
Last year’s fifth placing Pacific Golden Plover came in at 11th with 136 birds, down from 198 in 2020. In 12th position was Collared Kingfisher (124), followed by Olive-backed Sunbird (113), Olive-winged Bulbul (108), Pin-striped Tit-babbler (107), Common Iora (103), Rock Dove (101) and the globally near-threatened Long-tailed Parakeet (100). In 19th place was the Asian Openbill (98) that only invaded Singapore in huge numbers in late 2019. In 20th place was the ever-increasing introduced Red-breasted Parakeet (80).
The Top Twenty Species of 2020 are provided below:
What about the sites? The most species diverse sites were Kranji Marshes with 70 species. The mixed habitats of marshland, grassland and open woodland provided at Kranji for a high biodiversity. Coming a distant second was Sungei Buloh Route 2 which had 56 species and third was Kranji Dam, with 47 species. The least species diverse sites were Lower Seletar Dam (27), followed by Chinese Garden, Mount Faber and Pasir Ris Park, all with 28 species.
How about numbers? Well, the sites with the most number of birds counted were Sungei Buloh Route 1 with 495 birds counted followed by Sungei Buloh Route 2 (460) and Kranji Marshes (456). The sites with the least number of birds were Lower Peirce Reservoir with 80 birds, followed by Sime Track, Central Catchment Nature Reserve (130) and Bukit Batok Nature Park (137).
Rare and interesting migratory species found during ABC2020 included Peregrine Falcon, Grey Plover, Drongo Cuckoo, Indian Cuckoo, Blue-winged Pitta, Red-rumped Swallow, Yellow-browed Warbler. Eastern Crowned Warbler and Black-browed Reed Warbler. Globally threatened species included Lesser Adjutant (2 birds at Mandai Estuary), Straw-headed Bulbul (national count of 77 birds) and Greater Green Leafbird (2).
Nationally threatened specialties included Little Grebe (2 birds), Great-billed Heron (5), Changeable Hawk Eagle (9), Red-wattled Lapwing (11), Rusty-breasted Cuckoo (3), Mangrove Pitta (2 birds on Pulau Ubin), Asian Red-eyed Bulbul (7), Chestnut-winged Babbler (2), Oriental Magpie-robin (30) and White-rumped Shama (18)
This census would not have been possible if not for the counters who braved the elements and helped us to complete our 35th year of census. So, our grateful thanks to 39 volunteers.
