Records Committee Decision 2021

At a meeting on 13 May 2021, the Records Committee made the following decisions.

Additions to Cat I
●        Goldcrest Regulus regulus at Po Toi on 31 March 2020, followed by record at Tai Po Kau on 20 April 2020.
●        Jacobin Cuckoo Clamator jacobinus (spp pica) at Mai Po on 30 May 2020.
The HK List now stands at 564 species in Cat I and II.

Addition to Cat III
Ryukyu Scops Owl Otus elegans firstly reported near Tai Lung Experimental Farm, Sheung Shui, on 25 July 2020.

Taxonomy and HK List nomenclature changes:
An updated HK List will soon be published. It incorporates changes introduced in the recent IOC v11.1 and v11.2 species and taxonomic updates as follows:

Black-tailed Godwit: add newly described subspecies bohaii, which is larger in size compared to melanuroides and is the common wintering form in HK.

Collared Owlet: to be moved and resurrected Taenioptynx (Salter et al. 2019). i.e. Taenioptynx brodiei

Siberian House Martin: Common House Martin Delichon urbicum in Hong Kong to be renamed to Siberian House Martin Delichon lagopodum in the coming HK List after the proposed split was accepted in IOC v11.2 (and details referred to Leader et al. 2021).

IUCN Red List status
Dalmatian Pelican and Japanese Night Heron were downgraded to Near-threatened (NT) and Vulnerable (VU) respectively.

Changes of committee structure and chairperson
RC is re-structured by increasing members and the establishment of a “Checklist Sub-committee”. Records Committee maintains the main function of assessing the records of species that are considered rare or are seen in unusual circumstances in terms of numbers, location or date. The Records Committee comprises 4 to 6 members. New members are being recruited.

The new Checklist Sub-committee is to maintain and update the HK List by reviewing species which could probably be added or removed from the HK List. Any potential to affect the status of any taxon on the HK List should also be assessed by the sub-committee. The Checklist Sub-committee comprises 3 members.

Mr. Geoff Carey decided to step down as RC chairman, it was agreed Yu Yat-tung would be the next RC chairman. Records Committee current members include Yu Yat-tung (Chairman), Gary Chow, Paul Leader, and Richard Lewthwaite.

The Records Committee thanks Geoff for his great contribution in the last 30 years.

Yu Yat-tung
RC Chairman

領鵂鶹: 改變及復用Taenioptynx (Salter et al. 2019). 因此是 Taenioptynx brodiei

遠東毛腳燕(暫定中文名): 在香港的毛腳燕Delichon urbicum在即將刊登的香港鳥類名錄中被改為遠東毛腳燕Delichon lagopodum,原因是《世界鳥類名錄》v11.2接納這分種的提議( 詳情要參考Leader et al. 2021) 。

Hi Tung.
What about Ryukyu Flycatcher Ficedula owstoni which has been split from Narcissus Flycatcher by the IOC (Version 11.2 draft)?



Hi David,

Please advise me if I am wrong in the following comment.

As far as I know, the IOC v11.2 draft is still not being totally accepted (and otherwise it would not be called as draft) and just a bit more formality needs to be done from IOC for final acceptance. Once IOC announce the results, we will accept those split (or lump) from following the IOC list.



Addition to Cat III
Ryukyu Scops Owl Otus elegans firstly reported near Tai Lung Experimental Farm, Sheung Shui, on 25 July 2020.

What about the earlier records of the Ryukyu Scops Owl, going back to May 2020? Were these not assessed by RC, or were they considered Not Proven?
I would be interested to see an explanation of the Cat III decision for this record. Has the RC uncovered any evidence of captive trade, or is this decision based on caution due to a lack of other records on mainland Asia?


I know from experience that the RC can only consider what is placed before it.



At a meeting on 12 Jul 2021, the Record Committee confirmed the recruitment of new members:

RC committee members: Gary Chow, Matthew Kwan, Tom Li, Sherman Yeung and Yat-tung Yu.

Checklist sub-committee members: Paul Leader, Richard Lewthwaite and Yat-tung Yu.

During this meeting, new members were briefed on the RC working mechanism.

At a meeting on 5 Oct 2021, the Record Committee made the following decisions.

Addition to Cat I
Herald Petrel Pterodroma heraldica on 17 March 2001 at Mai Po boardwalk. This record was previously accepted as unidentified Pterodroma petrel, and is now being accepted with more updated identification criteria available in the literature and from internet photos.
Short-toed Snake Eagle Circaetus gallicus on 7 Nov 2020 at Lamma Island.
Swinhoe’s Storm Petrel Oceanodroma monorhis on 27 Oct 2020 at Ap Lei Chau, HK Island. This individual was found injured and sent to KFBG for treatment. After rehabilitation, it recovered to good condition and was released into the wild at Clear Water Bay on 17-11-2020
Large Cuckooshrike Coracina macei on 31 Oct 2020 at Tai Po Kau headland.
Black-chinned Yuhina Yuhina nigrimenta on 20 Jan 2021 at KFBG.
Ryukyu Minivet  Pericrocotus tegimae on 14 Feb 2021 at Mt. Davis, HK Island.
Ring-billed Gull Larus delawarensis on 20 Mar 2021 at Mai Po boardwalk.
Short-billed Gull Larus brachyrhynchus on 25 and 26 Feb 1994 at Mai Po boardwalk, a recent split from Common Gull Larus canus accepted by IOC version 11.2. This taxon, previously treated as a subspecies of Common Gull, has been included in the HK list and the latest review of this record still agrees with this decision.
Ryukyu Flycatcher Ficedula owstoni is also a new split from Narcissus Flycatcher Ficedula narcissina accepted by IOC version 11.2. The earliest accepted record was on 24 Mar 2002 at Mt. Davis, with seven accepted records subsequently. RC had only accepted records of male birds in spring (March to April), as there was no progress on reviews of female records.

The HK List now stands at 573 species in Cat I and II.

Addition to Cat III
Bar-headed Goose Anser indicus on 28 May 2021 with two individuals at Fung Lok Wai.

Removal of URF submission requirement
The following species would be removed from URF submission: Brown Bobby, Sooty Tern, Common Chiffchaff, Rustic Bunting, Barred Cuckoo-dove, Chestnut Munia.

An updated HK List will soon be published. It incorporates changes introduced in the recent IOC V.11.2 species and taxonomic updates.

信使圓尾鸌 Pterodroma heraldica (2001-03-17) 於米埔浮橋記錄及拍攝到。之前是被判斷為不能分辨的圓尾鸌類,現在有更新的文獻資料及網上的照片,所以現在記錄被接納。
短趾鵰 Circaetus gallicus (2020-11-07) 於南丫島記錄。
黑叉尾海燕 Oceanodroma monorhis (2020-10-27) 於香港仔鴨脷洲記錄,發現時已受傷及被送到嘉道理農場作診治,康復及回復狀態後,於清水灣野放重回大自然 (2020-11-17)。
大鵑鵙 Coracina macei (2020-10-31) 於大埔滘海岬記錄。

琉球姬鶲 Ficedula owstoni 都是最近在世界鳥類名錄 11.2版本中由黃眉姬鶲Ficedula narcissina分拆出來的一個新鳥種。最早被確認的紀錄於摩星嶺記錄(2002-03-24),及後到最近有七個被接納的紀錄。紀錄委員會只有接納到雄鳥的春天紀錄(三至四月),而雌鳥紀錄的評審仍未有進展。

I think swinhoe's storm petrel is a lot more common than we thought, maybe it's a rare but annual passage migrant.
