Addition to Cat I
- Velvet Scoter Melanitta fusca , Tsim Bei Tsui Jetty, 9 April 2023.

Addition to Cat IIB
- Indochinese Green Magpie Cissa hypoleuca
This species has been found expanding its location widely in NE New Territories and there was a recent observation at Shek Kung Catchwater. Breeding was also recorded in several location. Sustainable breeding population in Hong Kong has been established.

- White-rumped Shama Copsychus malabaricus
This species was formerly found only in Lion Rock Country Park. During the recent Hong Kong Bird Atlas Survey on 2016-19, this species was recorded in many locations at Sai Kung area as well and there were also records at Tai Po Kau recently. Breeding was confirmed at Sai Kung and breeding population was established locally.

The HK List now stands at 581 species in Cat I and II. An updated HK List will be published later.

Hong Kong Bird Report
HKBR 2020 is now in the final stage of typesetting work and it is expected to be published in coming months. This report will have only PDF version but no printed copy.

IOC World Bird List 14.1 and proposed changes of English Bird Name

The split of Intermediate Egret made three new species, the species recorded in Hong Kong is Ardea intermedia which IOC decided the English name as Medium Egret. The HKBWS Record Committee decided not to follow IOC decision because the other two new splits: Yellow-billed A. brachyrhyncha and Plumed A. plumifera Egrets are found primarily in Africa and Australasia, both of them have only remote chances of occurring in Hong Kong. The new name causes more confusion and so the tradition name, Intermediate Egret, is retained in the Hong Kong List.

The split of Oriental Dwarf Kingfisher made the species found in Hong Kong is now named as Black-backed Dwarf Kingfisher Ceyx erithaca. RC decided to accept this change and the HK List will follow this change.

The split of Olive-backed Sunbird made the species recorded in Hong Kong is now named as Ornate Sunbird Cinnyris ornatus. RC decided to accept this change and the HK List will follow this change. Accepted wild individuals of this species found in Hong Kong clearly showed whitish belly which is a characteristic field feature for the subspecies rhizophorae.

Anarhynchus replaces Charadrius as the genus name for several small plover species.

Change of sequence is applied in Shorebirds, Gulls and Terns. Genera between Pluvialis and Glareola are in new sequence, while terns are now preceding the gulls and many are internally re-sequenced.

The next meeting is scheduled in April or May 2024. (Update: The next meeting is postponed to June or July 2024.)

紀錄委員會於2024年1月22日舉行會議,作出以下決定。

加入第I類鳥種
絲絨海番鴨Melanitta fusca於尖鼻嘴碼頭記錄(2023-04-09) 。

加入第IIb類鳥種
印支綠鵲Cissa hypoleuca
該鳥種在新界東北部廣泛分佈,最近在石崗集水區也有觀察結果。在幾個地方也經有繁殖記錄,香港的繁殖種群已經建立。

白腰鵲鴝Copsychus malabaricus
該鳥種以前僅在獅子山郊野公園發現。在2016-19年度的香港鳥類分佈調查中,西貢地區多處均錄得該鳥種,最近在大埔滘亦有記錄。在西貢亦確認有繁殖紀錄,香港的繁殖種群已經建立。

《香港鳥類名錄》第I類及第II類遞增至581種,更新的香港鳥類名錄亦會再同時出版。

香港鳥類報告
香港鳥類報告2020的製作已進入尾聲, 現正進行最後的排版,預計在未來數月內會出版。這本報告將會出版電子版而沒有印刷版。

世界鳥類名錄14.1及英文鳥類名稱改動建議

中白鷺被拆為三個鳥種, 在香港出現的為Ardea intermedia ,世界鳥類名錄建議使用新的英文名稱 Medium Egret 。紀錄委員決定不跟隨這個建議 , 原因為另外兩個分拆的中白鷺新種為Yellow-billed Egret A. brachyrhyncha 及Plumed Egret A. plumifera  ,其分佈在非洲及澳大拉西亞地區, 牠們要是在香港出現的機會是非常少 , 而且這個新英文名稱會帶來混亂。 因此故有的英文名稱Intermediate Egret會繼續使用 , 中文名稱亦沒有改動。.

三趾翠鳥的新分拆使到在香港的紀錄改為Black-backed Dwarf Kingfisher Ceyx erithaca。紀錄委員會決定接受這個改動,中文名稱沒有改變。

黃腹花蜜鳥的新分拆使到香港的紀錄改為Ornate Sunbird Cinnyris ornatus。紀錄委員會決定接受這個改動,中文名稱沒有改變。在香港發現的野生個體有著明顯易認的白色腹部,這是rhizophorae亞種的特徵。

Anarhynchus 代替 Charadrius 作為幾種小型鴴類的屬名。

涉禽、鷗及燕鷗的排列次序列有改變。PluvialisGlareola 這兩個屬有新的次序,而燕鷗現在排列於鷗之前,並且多個鳥種在內部亦有重新排列。

下次會議安排在2024年4或5月。(更新:下次會議延期在2024年6月或7月。)

香港觀鳥會紀錄委員會主席
余日東
