Checklist Revisions

Checklist Revision for February 2022

Prepared by the Singapore Bird Records Committee

The latest update of our checklist, version 2022-1, has been published. It can be accessed at our Downloads page.

Since the last bird list revision in September 2021, our team has voted on over 100 records of rare species in Singapore. Although our latest votes are always available at our Recent Decisions page, we will continue to publish regular updates to keep our readers updated on the latest avifaunal developments, including recent advances in taxonomy. 

Along with this update, we are also launching a live version of our checklist! For the past six years, the Singapore Birds Project has published checklists every half a year. However, with the growth in observer effort and information available, the combined knowledge of Singapore’s birding community is rapidly increasing. Within a short span of five months since our last checklist update, the checklist has seen a net gain of seven species. We will continue to release half-yearly checklist updates in Excel format, but latest developments can be tracked in the live checklist.

There are now three versions of our checklist: the simplified live list on our main website, the more detailed live checklist on our Records Committee site, and lastly, a snapshot of the checklist published at regular intervals, accessible at our Downloads page. The first two are updated as the Records Committee evaluates new records, while the snapshot is typically updated twice a year along with IOC taxonomic revisions.

Our downloadable checklist now also comes with new information on each species, including status in the Singapore Red Data Book, as well as rarity status (based on our Rarities List), local status, checklist category, and links to our Singapore Bird Database for relevant species.

Added to checklist

Ashy-headed Green Pigeon Treron phayrei [Record 10001]: The committee deliberated extensively on this bird recorded at Dillenia Hut from 9 to 11 Oct 2021. This species is not known to occur south of the Isthmus of Kra, with no records in Malaysia, but Treron pigeons are known to wander widely in search of fruit sources. The final decision was to accept the individual as a wild bird and place the species in Cat A (for species that have occurred naturally in the wild within the last 30 years), a thorough discussion of this record is available in this article and at the link above.

Spotted Flycatcher Muscicapa striata [Record 10002]: One record at Kent Ridge Park from 15-29 Oct 2021. While there are recent records in the Philippines and Taiwan, this is the first record for continental Southeast Asia. The committee voted unanimously to place this species in Cat A.

Tree Pipit Anthus trivialis [Record 10005]: A single bird off Clementi Road, 19-31 Oct 2021. Like the Spotted Flycatcher, this species is a long-distance migrant with most of the population wintering in India and Africa. Regarded as a vagrant and placed unanimously in Cat A.

Common Starling Sturnus vulgaris [Record 10082]: One record of a single bird at Marina East Drive from 13 to 15 Dec 2021. A known vagrant with records in Malaysia and further north, as well as Borneo, but this is the first national record. Placed in Cat A on a unanimous vote.

Black Redstart Phoenicurus ochruros [Record 10069]: One record at Pasir Panjang, first seen on 28 Nov 2021 and subsequently by many observers; still present as of Feb 2022. Age, sex, and subspecies remain unclear as of writing, but further observation of the bird may provide more insight. Regarded as a vagrant and unanimously placed in Cat A.

Cinereous Vulture Aegypius monachus [Record 10106]: A vagrant individual with Himalayan Griffons Gyps himalayensis at Singapore Botanic Gardens, 29-30 Dec 2021; subsequently found weak and unable to fly near Holland Road. Rescued, rehabilitated, and released early this year. Placed in Cat A on a unanimous vote.

Pale-legged Leaf Warbler Phylloscopus tenellipes [Record 10030]: One record of a vagrant present from 12 Nov to at least 3 Dec 2021 at Macritchie Reservoir was unanimously accepted and the species placed in Cat A. This species is a regular winter visitor to Thailand but is believed to be rarer than the visually identical Sakhalin Leaf Warbler P. borealoides further south in the peninsula.

Previous records not accepted, but species maintained in checklist

Grey-streaked Flycatcher Muscicapa griseisticta [Record 10032; Record 748]: A previous record in April 1991 was reviewed by the committee and not accepted as the descriptions provided do not conclusively rule out Dark-sided Flycatcher M. sibirica. However, a single bird present from 9-17 Nov 2021 was accepted as the first national record and the species was therefore retained in the checklist in Cat A.

Scarlet-breasted Flowerpecker Prionochilus thoracicus [Record 10056; Record 10055]: Upon review by the committee, a record from 1 Jan 2015 was not accepted due to lack of supporting evidence. The record of an individual at Bukit Timah Nature Reserve on 29 Nov 2021 was, however, accepted and the species was retained in the checklist in Cat A.

Considered for inclusion

Long-eared Owl Asio otus [Record 10042]: After much deliberation, the committee decided on a split vote that the single sighting of this bird at Marina East Drive on 20 Nov 2021 most likely pertained to a ship-assisted individual rather than a wild bird. For more detailed discussion of this record, see the record linked above.

Removed from checklist

Temminck’s Stint Calidris temminckii [Past records]: As the last record of this species in Singapore was in Oct 1984, it exceeds the 30-year threshold for inclusion in the checklist. The committee placed this species in Cat B1 (for species which would appear in Cat A, but without records within the last 30 years).

Eurasian Coot Fulica atra [Past records]: Like Temminck’s Stint, this species has not been recorded locally in the last 30 years and was therefore assigned to Cat B1 and removed from the checklist.

Still pending review

Christmas Frigatebird Fregata andrewsi [Record 10163]: A record in May 2013 was outside Singapore’s territorial waters; the most recent confirmed record within Singapore’s geographical boundaries was in May 1986, which exceeds the 30-year threshold for inclusion in the checklist. If the record from Marina East Drive (see record linked above) is accepted, the species would be moved from the Annex to Cat A.

Other minor change

Stejneger’s Stonechat is renamed to Amur Stonechat following taxonomic updates by the IOC.
