Record Committee Decision 2025

At a meeting on 21 January 2025, the Record Committee made the following decisions:

Addition to Cat I

• Black Eagle Ictinaetus malaiensis – recorded at Po Toi on 31 October 2023
With increasing records in neighbouring region (i.e. Pearl River Delta), good plumage condition, suitable location and date of this record, this species is added into Cat I of the Hong Kong bird list.

Addition to Cat III

• Little Pied Flycatcher Ficedula westermanni – recorded at Po Toi on 7 December 2023
Given this species’ natural distribution, being sedentary and date of this record, this bird is more likely not of natural origin.

• Crimson Sunbird Aethopyga siparaja – recorded at Tuen Mun on 24 December 2023 and Po Toi on 4-6 January 2024
Evidence of feather damage and sub-urban location of the first record suggests it may have originated from captivity. The second record refers to an individual which could not be assigned to subspecies identification due to lack of good quality photos. In addition, different species of sunbird were found in the local bird market in that period. All these are favour to place this species in Category III based on these available information.

New subspecies record

• Ornate Sunbird Cinnyris ornatus subspecies flammaxillaris – recorded at Lion Nature Education Centre, Sai Kung on 18 November 2024
This is a similar case to the Little Pied Flycatcher. Given this species’ natural distribution, being sedentary and date of this record, this bird is more likely not of natural origin.

The HK list now stands at 585 species in Cat I and II. An updated HK List will also be published.

Species under review

Mountain Hawk Eagle Nisaetus nipalensis at Long Valley, 5 October 1995
- Second review concluded as Not Proven. This species remains in Category I of the Hong Kong List from the only accepted (and the first) record at Luk Keng, 7 May 1988.

URF assessment update

- In progress. Birdwatchers are still encouraged to submit URF to HKBWS Record Committee.

Hong Kong Bird Report

- HKBR 2021 is now under preparation and HKBR 2022 is under planning.

HKBWS & eBird Partnership

• Official collaboration started; open data from eBird can now be used by HKBWS.
• eBird is actively promoted to encourage bird record submissions.

IOC Update (Version 15.1 draft)

• No changes affecting the Hong Kong List.

IUCN Red List Update

• No changes for Hong Kong species.

Satellite-Tracking Data in Bird Records

• Discussion on whether tracking data alone should count as a formal records in Hong Kong including the “first record”.
• Key concerns are lack of direct visual confirmation and potential behavioral changes (human-induced) in tracked birds.
• No final decision yet; further discussions and references to other record committees are planned.

Date of next meeting
•        April - May 2025

Chairman, Record Committee

紀錄委員會於2025年1月21日舉行會議,作出以下決定。

加入第I類鳥種

• 林鵰Ictinaetus malaiensis — 2023年10月31日於蒲台島記錄
隨著鄰近地區(即珠江三角洲)的記錄增加、該鳥羽毛狀況良好、合適的地點和日期,這鳥種被列入香港鳥類名錄的第 I 類鳥種。

加入第III類鳥種

• 小斑姬鶲Ficedula westermanni — 2023年12月7日於蒲台島記錄
鑒於該鳥種的自然分佈、留鳥的特性及本記錄的日期,這種鳥很可能並非自然遷徙至香港。

• 黃腰太陽鳥Aethopyga siparaja — 2023年12月24日於屯門、2024年1月4日至6日於蒲台島記錄
第一個記錄的照片顯示該鳥羽毛有損傷和接近市區的位置表明牠有可能源於籠養。第二個記錄則由於缺乏高質素照片而無法鑒定這個體的亞種。此外,在此期間有發現本地鳥類市場出售多種太陽鳥。根據這些資訊,紀錄委員會認為把這鳥種歸入第III類鳥種是最適合的做法。

新增亞種記錄

• 黃腹花蜜鳥Cinnyris ornatus亞種 flammaxillaris — 2024年11月18日於西貢獅子會自然教育中心記錄
這與上述的小斑姬鶲的情況類似。鑒於這鳥的自然分佈、留鳥的特性及和這記錄的日期,這種鳥很可能不是自然起源的,推測可能來自籠養/放生。

《香港鳥類名錄》第I類及第II類遞增至585種,更新的香港鳥類名錄亦會再稍後出版。

鳥種審議

鷹鵰Nisaetus nipalensis - 1995年10月5日於塱原
•第二次審查的結論是未能證實。這鳥仍被列入香港鳥類名錄的第I類鳥種,記錄來自唯一被接納的(亦是首次)紀錄在1988 年 5 月 7 日於鹿頸 。

罕有雀鳥紀錄表(URF)評估更新

•  繼續進行中,紀錄委員會仍收集及鼓勵觀察者提交URF及其他鳥類記錄。

《香港鳥類報告》進度

• 香港鳥類報告2021目前正在準備中,香港鳥類報告2022亦開始進行規劃。

與eBird合作

• 香港觀鳥會與eBird正式展開合作,eBird開放數據可供香港觀鳥會使用。
• 香港觀鳥會正推廣eBird,鼓勵觀鳥者提交鳥類記錄。

世界鳥類名錄(IOC)更新(15.1版本)

• 沒有涉及香港鳥類名錄的變更。

IUCN紅色名錄更新

• 沒有涉及香港鳥種的變更。

衛星追蹤數據作為首筆記錄的爭議

• 討論是否應接受僅憑衛星追蹤數據作為正式的在香港的紀錄,包括「首個紀錄」。
• 主要爭議點為沒有直接觀察個體的證據,以及追蹤設備(人為因素)可能改變鳥類本身的行為。
• 未有最後決定,需要更多討論及參考其他鳥類紀錄委員會的做法。

下次會議時間

• 擬定於2025年4 - 5月舉行。

紀錄委員會主席
余日東
