12 Hong Kong Bird Report : Editorial Preface Editorial Preface The years 2007 and 2008 both proved to be very good, with the two highest annual species totals since HKBWS records began. It remains to be seen whether this is a oneoff phenomenon, or whether it sets a pattern for the future. The rise in the number of photographers in particular has resulted in a number of records of species new to or rare in HK that otherwise may have gone unnoticed. In addition, the rewards of regularly visiting Po Toi during the migration seasons are amply demonstrated by the number of firsts that have been recorded on the island: five in , with two in the seas nearby. This is in addition to three in The editorial team is working hard to publish reports in order to clear the backlog. This bumper edition was put together in approximately eight months, and the aim is to be in a position to revert to single-year reports for the 2011 edition. GJC would like to express his gratitude to JAA and GC for their work, but in particular to GW for his ceaseless and untiring efforts in ensuring this report came out much more smoothly and quickly that it would otherwise have done. The editorial team would like to thank the translators who carried out this time-consuming task.

13 Hong Kong Bird Report : Editorial Preface 編者序言 2007 及 2008 年為觀鳥的大好年份, 因為這是香港觀鳥會自有紀錄以來最高鳥種數目的兩年, 我們且看這是偶發現象還是大勢所趨 近年鳥攝者數量的增加亦造就了一些新鳥種或稀有鳥種的紀錄, 否則牠們的存在依然未為人所知 此外, 遷徙季節期間我們在蒲台島的定期觀察亦獲得可觀的回報 : 年共 5 個香港新鳥種, 另有兩個新鳥種於附近海域發現 ; 而在 則只有三種 編輯部正在努力不懈地繼續出版餘下的年報, 而這本特厚的雙年年報前後花了差不多 8 個月時間完成, 我們的目標是要在 2011 年開始回復出版單年年報 本人賈知行非常感謝 JAA 及周家禮先生的協助, 還有 GW 從無間斷及不屈不撓的投入, 否則出版這年報便不會如此順暢及有效率地完成 最後非常感謝負責翻譯的義工協助完成這項費時的工作 主編賈知行 編輯 Geoff Welch, John Allcock 及周家禮 翻譯義工陳芳玲 陳健德 陳盈之 周麗娟 何煒筠 許桓峰 李佩玲 梁嘉善 李安琪 謝穎詩及余海寧

28 Hong Kong Bird Report : Records Committee Report Records Committee Report Geoff J Carey Records Committee Chairman The taxonomy of birds is in flux, and in order to to ensure the Hong Kong List remains in line with the most recent advances in taxonomy, the Records Committee decided at its meeting on 1 st March 2010 to align the Hong Kong List with that of the International Ornithological Congress (IOC). However, while scientific names will, therefore, follow those adopted by the IOC, English names may not. Although our aim is to use, where possible, the English names proposed at worldbirdnames.org for the IOC List, where the RC feels there is a particular issue, we reserve the right to use an alternative name. In addition, the categorisation system for the HK List has also been revised. The primary change concerns the removal of Category B, which previously comprised species that appeared to have occurred in a wild state, but for which the possibility of non-natural origin could not be satisfactorily ruled out. Species previously in this category have been reassigned to Category I or III as appropriate. The previous Categories C and D, which comprised breeding species of presumed or known nonnatural occurrence, have been included as sub-divisions of the same category, to reflect their essentially similar nature. An extra sub-division in this category contains species that no longer have self-sustaining populations. Finally, species in the previous Category F have been relegated to an appendix, to highlight that they are not part of the main HK List. The new categories are as follows: Category I: species that have been recorded in an apparently wild state in HK (a direct replacement of the previous Category A). Category IIA: southeast China breeding species, the currently established HK breeding population of which is considered to derive from captive stock, but which probably occurred in HK prior to habitat changes (previously Category C, excluding species that have died out). Category IIB: extralimital species that, although originally introduced to HK by man, maintain a regular feral breeding stock without necessary recourse to further introduction (previously Category D, excluding species that have died out). Category IIC: previously established feral species (i.e. species from Categories IIA and IIB that no longer have self-sustaining populations). Category III: species for which all published HK records are considered likely to relate to birds that have escaped or have been released from captivity (previously Category E). During 2007 a total of 380 Category I and II species were recorded, while the equivalent figure for 2008 was 381. These compare with 367 and 375 in 2005 and

29 Hong Kong Bird Report : Records Committee Report respectively, between 318 and 355 species for the years 1999 to 2004, and between 342 and 370 for the years 1993 to It is likely that 2007 and 2008 have seen the highest number of species recorded in a single year, though taxonomic changes over time make it slightly problematic to make a comparison with previous years. A total of 14 first records of full species as additions to Category I is certainly very high for a two consecutive year period. New additions to the HK List that occurred during or prior to 2007 and 2008 were as follows. Additions to Category I Black Scoter Melanitta americana One at Mai Po NR on 9 December Yellow-billed Loon Gavia adamsii One near Town Island during January White-tailed Tropicbird Phaethon lepturus A juvenile photographed southeast of Po Toi on 4 May Masked Booby Sula dactylatra One seen off Po Toi on 18 March Steppe Eagle Aquila nipalensis A first-winter photographed at Mai Po NR on 22 December Western Water Rail Rallus aquaticus One at Mai Po NR during 2-8 December Japanese Murrelet Synthliboramphus wumisuzume One photographed in southern waters on 5 May Common Cuckoo Cuculus canorus One photographed on Po Toi on 4 April Brown Wood Owl Strix leptogrammica One photographed at Lead Mine Pass on 6 November Red-backed Shrike Lanius collurio A first-winter photographed at Ho Man Tin, present during 6-9 October Willow Warbler Phylloscopus trochilus One photographed at Long Valley on 25 October Plain-tailed Warbler Seicercus soror One photographed at Tai Po Kau on 9 October

30 Hong Kong Bird Report : Records Committee Report Japanese Swamp Warbler Locustella pryeri One trapped at Mai Po NR on 10 November Lesser Whitethroat Sylvia curruca One trapped at Mai Po NR on 15 October Hodgson s Redstart Phoenicurus hodgsoni One photographed on Po Toi on 11 December Slaty-backed Flycatcher Ficedula hodgsonii A first-winter photographed at Tso Kung Tam, near Tsuen Wan, present from 10 February to 2 March Red-breasted Flycatcher Ficedula parva One on Po Toi during 4-11 April 2007 was the first record accepted for Hong Kong. Subsequent review of previous photographs resulted in records pre-dating this, on 3 April 2005 on Po Toi and on 27 December 2005 at Sha Tau Kok. In addition, the first record of the central China breeding taxon of Blue-and-white Flycatcher Cyanoptila cyanomelana cumatilis was photographed on Po Toi on 19 October Additions to Category III Purple Cochoa Cochoa purpurea One photographed on Po Toi on 11 October Red-headed Bunting Emberiza bruniceps One along the Mai Po access road on 10 January The Systematic List for the two years was compiled by the following: Geoff Carey: galliformes, rails and allies, larids, warblers to flycatchers and Category E species. Yu Yat Tung: grebes to ducks, shorebirds. Richard Lewthwaite: raptors, doves to martins. John Holmes: swallows to parrotbills. John Allcock: tits to corvids Geoff Welch: rarities.

31 Hong Kong Bird Report : Records Committee Report 紀錄委員會報告 紀錄委員會主席賈知行 鳥類的分類方法日新月異, 為了令香港的雀鳥名錄能緊貼最新的分類方法, 紀錄委員會於 2010 年 3 月 1 日的會議上將香港鳥類名錄與 International Ornithological Congress (IOC) 直接掛鈎 學名完全跟從 IOC 名錄, 但英文名卻不一定沿用 雖然我們希望採用在 worldbirdnames.org 網站上為 IOC 名錄而設的英文名, 但由於紀錄委員會覺得在某些情況下不太可行, 所以我們保留採用其他名稱的可能性 此外, 香港鳥類名錄的分類系統亦有所修訂 當中最主要的改動是剔除 B 類, 該類是指一些主要是野生但卻不能排除人為引入鳥種 這類別的鳥種在新的分類系統上歸納為 I 或 III 類 之前有繁殖紀錄的可能或確定為非源自野生的 C 及 D 類, 則納入在同一類別中的不同分屬, 以反映其相近的本質 而此類別也另增一個分屬, 包含了那些再不能維持穩定群落的鳥類 最後, 之前為 F 類的鳥種現已調至附錄中, 以示牠們並非屬於香港鳥類名錄之內的一部份 新的雀鳥類別如下 : 第 I 類 : 此鳥種曾於明顯的野生狀況下被記錄 ( 直接取代之前的 A 類 ) 第 IIA 類 : 在中國東南面繁殖的鳥種 ; 現時在香港已建立的繁殖種群被認為是源自飼養種群, 但可能早在自然生境出現變遷前已經在香港出現 ( 為之前的 C 類, 除了那些已消失的鳥種 ) 第 IIB 類 : 在自然分佈地區以外出現的鳥種 自人類引入後便無需借助額外幫助而能夠在香港繁衍 ( 為之前的 D 類, 除了那些已消失的鳥種 ) 第 IIC 類 : 較早以前建立野生群落的鳥種 ( 如 IIA 及 IIB 類但無法再維持穩定群落的鳥種 ) 第 III 類 : 所有被認為是逃逸或源自飼養種群的鳥種 ( 為之前的 E 類 ) 2007 年一共有 380 種第 I 及 II 類鳥種的紀錄, 而 2008 年有 381 種 2005 年及 2006 年分別有 367 種及 375 種 ;1999 至 2004 年間有 318 至 355 種 ;1993 年至 1998 年間有 342 至 370 種 雖然雀鳥分類上的改變令不同年份的雀鳥數目難以直接比較, 但我們可見 2007 及 2008 年是最多鳥種紀錄的年份 兩年內有 14 種新增鳥種紀錄肯定是一個非常高的數目 [ 其餘部份請參閱英文全文 ]

32 Hong Kong Bird Report : Annual Summaries Geoff Welch Annual Summaries 2007 and 2008 These summaries continue with the seasonal format introduced in the Annual Report. This breaks down as: winter (December to February), spring (March to May), summer (June to August) and autumn (September to November). As in previous years, the Systematic List takes precedence over the Summaries in the event of any discrepancies. Both 2007 and 2008 were exceptionally good years, with 380 and 381 species respectively setting new records for the number of species in one year, and an aggregate of 14 additions to the Hong Kong List, the highest count for two consecutive years since The increased number of both photographers and birders is largely responsible and the existence of the Forum on the HKBWS website allows high quality images to be published very soon after capture. Of the firsts, Slaty-backed Flycatcher, Red-backed Shrike, Willow Warbler and Steppe Eagle were identified from website photographs, and these and many other significant records would almost certainly have been missed or remained un-identified without them. Winter 2007 (January to February) Both January and particularly February were unseasonably warm with the monthly mean temperature for February being the highest on record, due to fewer than normal cold fronts passing through Hong Kong. Probably as a consequence, there were few new birds of note in January and February, with many of the interesting records involving birds present at the end of These included the first ever over-wintering Lesser Whistling Duck which remained at MPNR until 27 th May, the two juvenile Lesser White-fronted Geese which were seen in the Lok Ma Chau/MPNR area through to 29 th March, a single Ferruginous Duck at MPNR until 3 rd March, the White-bellied Green Pigeon seen at Airfield Road Shek Kong until 7 th January and two rare crows in the MPNR/Lut Chau area, a Daurian Jackdaw and a Carrion Crow, both present until 6 th April. The first two months of the year are traditionally the peak months for waterbirds in Deep Bay and a range of 57,000-64,000 has become established in recent years as the number present over this period. This year the peak total was 80,108, an excellent although rather surprising result given the relatively warm winter and there were record highest counts of Northern Shoveler (8,930), Tufted Duck (4,285) and Pied Avocet (11,957, more than double the previous highest). In contrast, the peak count of Common Shelduck was down to less than 50 birds, a significant decline from the turn of the decade when numbers exceeded 1,000, and for the first winter in memory no Dalmatian Pelicans were recorded

33 Hong Kong Bird Report : Annual Summaries A first-winter Japanese Cormorant seen off Po Toi from 4 th to 18 th January was a second HK record and the Orange-breasted Green Pigeon from 2006 put in a final appearance on Po Toi on 24 th January. A male Bay Woodpecker was present in Tai Po Kau for most of January; this species has now become a regular sighting there. February provided some new species with two Chestnut-bellied Rock Thrushes at KFBG from 1 st, a Common Reed Bunting trapped at MPNR on 3 rd followed by a Paddyfield Warbler on 17 th. Spring 2007 (March to May) March continued the warm spell with three rather weak cold fronts. April was better, with strong cold fronts on 3 rd and 18 th and a wet depression on 24 th, followed by others on 4 th and 18 th May. March was rather unexciting with few unusual species reported. A second Paddyfield Warbler was trapped at MPNR on 3 rd, this being a re-trap of a bird first trapped there on 6 th October 2006 and presumably having wintered in the area. A male Red-breasted Merganser was seen flying northeast off Po Toi on 16 th March; with the lack of recent records in Deep Bay, this species is now only seen on migration through southern waters in March. Spring really started with the first cold front on 3 rd April producing two firsts for Hong Kong, Common Cuckoo and Red-breasted Flycatcher, both on 4 th, and both on Po Toi. The Common Cuckoo was a one-day bird but the Red-breasted Flycatcher stayed until 11 th April, which was fortunate because the bird was initially identified as a Red-throated Flycatcher and the true identity was not recognized for several days. With an understanding of the identification features of Red-breasted Flycatcher, several other records were reported over the next two years as well as some prior to the first, which indicate the species may have been over-looked in the past. Also on 4 th April was a Ruddy Shelduck, the only record of the two years, which remained at MPNR until 24 th April. Wader passage in the Deep Bay area usually reaches its spring peak in April and this year the highest count of 15,149 on 21 st April set a new record since the start of the Shorebird Monitoring Programme. High counts were recorded for many species, particularly the two commonest, Red-necked Stint (2,239 compared to 1,478 in 2006) and Curlew Sandpiper (10,982 compared to 4,151 in 2006). Two species are always the centre of attention at this time Spoon-billed Sandpiper and Nordmann s Greenshank, Critically Endangered and Endangered respectively. Hong Kong remains an important staging post in the migration of both species, as well as for the Near-threatened Asian Dowitcher. Numbers of all three species were higher than normal, with at least seven Spoon-billed Sandpipers (one in 2006), 50 Nordmann s Greenshanks (32 in 2006) and 132 Asian Dowitchers (25 in 2006)

34 Hong Kong Bird Report : Annual Summaries Two seabirds of real quality in April/May were an adult male Christmas Island Frigatebird off Tung Ping Chau on 21 st April followed by the first record of Japanese Murrelet seen by many observers on a HKBWS boat trip in southern waters on 5 th May. This bird was in poor condition with much worn feathers that rendered it unable to fly. Also at sea, Short-tailed Shearwaters were seen from 30 th April to 23 rd May with a high count of 15 on 14 th, a pattern very similar to 2006 when their spring migration through HK waters was first discovered. Two Drongo Cuckoos appeared in the middle of April one at MPNR on 16 th and one on Po Toi on 19 th following the cold front. The depression on 24 th produced a Malayan Night Heron on Po Toi on 25 th which remained until 5 th May. The final act of spring was an influx of small bitterns on 21 st May following the depression on 18 th, with Yellow, Von Schrenck s, Cinnamon and Black Bittern all present in good numbers on Po Toi and elsewhere. Summer 2007 (June to August) This summer was drier than normal with just one Tropical Storm, Pabuk on 10 th August. Long term nest counts of ardeids made by the HKBWS Egret Research Group have shown that while the number of Great, Little and Cattle Egrets and Chinese Pond Heron has remained constant or showed a slight increase, Black-crowned Night Heron has declined annually since 2002, from 250 to 95 in Most nests of this species are found in the A Chau colony; as numbers of other egrets in this colony have not decreased in the same way, the cause is not clear. Red-billed Starling joined White-cheeked and White-shouldered Starlings as a confirmed breeding species with a record at Tai Mei Tuk. A juvenile Orange-headed Thrush at Kap Lung on 6 th June indicated successful breeding there and reports of Common Blackbird in MPNR car park throughout July also suggest breeding. Other interesting July reports included Grey-headed Lapwing at MPNR on 11 th, the earliest ever autumn record of Oriental Pratincole, an adult and a juvenile at Chek Lap Kok on 24 th, and a juvenile Grey Wagtail on Po Toi on 26 th. Early August records included a male Mallard at MPNR from 7 th, a Eurasian Hoopoe at Po Toi on the same date and a juvenile Cinnamon Bittern at Kam Tin on 9 th. Early migrants were an Aleutian Tern in eastern waters on 13 th, an Asian Paradise Flycatcher at Parker Hill on 15 th and a Yellow-rumped Flycatcher at Mui Tsz Lam on 18 th. Two August Hodgson s Hawk Cuckoos, at Mui Tze Lam on 13 th and Tai Po Kau on 18 th, are evidence of the continuing increase of this species in Hong Kong. An adult Brown Booby was in the East Lamma Channel on 25 th August and on rocks near Po Toi the following day

35 Hong Kong Bird Report : Annual Summaries Autumn 2007 (September to November) Autumn was warm and generally dry with no close approaches by Tropical Storms. There were no significant weather events until November, when two periods of strong northerly winds occurred from 1 st to 9 th and 26 th to 29 th. As a result, autumn 2007 was rather dull until November. September started with a Brown-chested Jungle Flycatcher trapped at Tai Po Kau on 1 st and present until 5 th. This was followed by the third Drongo Cuckoo of the year, on Po Toi on 3 rd and then a quiet period until a Fairy Pitta at Shing Mun on 26 th September. A Ferruginous Flycatcher at Tai Po Kau on 4 th October was a rare autumn record and 121 Blue-tailed Bee-eaters going to roost at MPNR on 5 th October was more than double the previous highest count. The second Christmas Island Frigatebird of the year was seen at south Lamma on 4 th October and a Speckled Piculet was photographed at Ng Tung Chai on 6 th. Finally for October, a female Purple Cochoa on Po Toi on 11 th October was a surprise addition to Category III. Four records of note on Po Toi in early November were a Bianchi s Warbler on 5 th, which remained into January 2008, the first ever autumn Narcissus Flycatchers, a male on 6 th and a female on 11 th, a second Red-breasted Flycatcher following the spring first record on 10 th and up to four Japanese Yellow Buntings over the period 10 th to 28 th November. These were the first autumn records for Japanese Yellow Bunting in HK but more excitingly, one was ringed and photographs allowed its ring number to be read. It was later confirmed that the bird had been ringed as a juvenile in north Honshu, Japan, 3000 kms away, just 34 days earlier. The best birds of the autumn were two firsts for HK, a Brown Wood Owl photographed late in the evening of 6 th November at Shing Mun and a Japanese Swamp Warbler trapped at MPNR on 10 th November. This was followed by a Pallas s Reed Bunting trapped at the same site on 17 th November. One of the surprising sites of the autumn was Lai Chi Kok Park, where in quick succession from 24 th to 30 th November, the following species were recorded Northern Boobook, Slaty-legged Crake, Eurasian Woodcock, Savanna Nightjar, Pallas s Grasshopper Warbler, Lanceolated Warbler, Grey Nightjar and Eurasian Eagle Owl. Many were photographed walking across lawns, exposed in trees or even sitting on football pitch goalposts, an amazing set of records for a modest suburban park. Even better was to follow from this location in January Winter (December to February) The weather in December and January was quite normal until an intense cold front arrived on 23 rd January. Temperatures fell suddenly and remained very low until 16 th February, the longest official cold spell for 40 years and the coldest February for 40 years. This cold spell affected all of south and central China and an influx of some

36 Hong Kong Bird Report : Annual Summaries species of thrushes and chats began in early February, most noticeably at Sai Kung CP and Pui O, as well as an arrival of other species that were probably also weather affected. The total peak count of all waterbirds in the Deep Bay area once again achieved a new high figure, 90,986, with Northern Shoveler (14,253) and Pied Avocet (16,123) making new record counts. One reason for these increases is thought to be improved management of the Futian National Nature Reserve on the Chinese side of Deep Bay. Numbers of Common Shelduck continued to fall, with a maximum of just 24. On the positive side, 16 Falcated Duck in late March was a very good count, as were 728 Eurasian Coot on 14 th January. A single Dalmatian Pelican from 20 th February to 5 th March was a welcome sight after their total absence in There has been a dramatic fall in the numbers of this species wintering in east China, and it is now thought to number just 30 birds. Waterbird of the winter was a female/immature Black Scoter which was present on Pond 20 at MPNR for just one day, 9 th December, and was another HK first, as was a female Hodgson s Redstart seen briefly on Po Toi on 11 th. A White-spectacled Warbler over-wintered at Tai Po Kau and the third Red-breasted Flycatcher of the year arrived on Po Toi on 18 th December, staying until late January when it probably became a victim of the cold weather started with an excellent set of photographs of a Pale-footed Bush Warbler in Lai Chi Kok Park on 6 th January. As all previous records of this species in HK had been trapped, a large number of bird-watchers and photographers once again descended on this suburban park, only to find the bird gone. A female Red-headed Bunting seen on the Mai Po Access Road on 10 th January was the first record of the species in Hong Kong, but its plumage condition suggested it was ex-captive. A first-winter Glaucous Gull from the Mai Po boardwalk on 13 th January stayed only one day, but a first-winter Relict Gull on the same date stayed longer, with up to two being seen until 2 nd March. The next HK first arrived in the shape of a Yellow-billed Loon off Town Island on 25 th January. This bird may well have been brought south by the cold weather, as may also another Loon, a Red-throated seen from Po Toi between 13 th and 27 th February, the third record for HK. The cold spell may also have been responsible for the arrival of yet another first, a female Slaty-backed Flycatcher near Tsuen Wan on 10 th February. This was another bird identified from photographs posted on the website, and it remained until 2 nd March enabling many people to see and photograph it. So ended an exciting winter with a total of four HK firsts

37 Hong Kong Bird Report : Annual Summaries Spring 2008 (March to May) Spring 2008 was an active spring for weather, with cold fronts or depressions on 30 th March, 12 th and 22 nd April, 1 st, 5 th, 9 th and 18 th May and a rare spring typhoon, Neoguri, on 19 th April. March started with a first-winter Slender-billed Gull joining the Relict Gull at the MPNR Boardwalk on 1 st March and staying until at least 21 st. A Black Bittern also at MPNR on 9 th March was by far the earliest spring record for this species, and a Speckled Piculet was at Bride s Pool on 14 th March. These were followed by another HK first, an immature Masked Booby flying past Po Toi on 18 th March in a loose flock of Heuglin s Gulls. Finally for March, another Red-breasted Flycatcher appeared on Po Toi with the first cold front of the spring on 31 st. Grey-faced Buzzards also came with this cold front, 44 on 1 st and 98 on 2 nd April over Po Toi. A HKBWS boat trip on 5 th April found two Pomarine Skuas, three Parasitic Jaegers and at least 40, possibly as many as 60, Long-tailed Jaegers plus an unfortunate immature Black-legged Kittiwake photographed on the receiving end of an attack by a Parasitic Jaeger. A Eurasian Jay heard at Tai Lam CP on 6th April was the first live record since 2002, although captive origin cannot be ruled out. The Po Toi lighthouse was an unusual location for a Fairy Pitta on 10th April and a Brown Bush Warbler in song at Robin s Nest on 14 th was the first April record for the species. Another Pitta, this one a Blue-winged and the second record for HK, was first photographed on Po Toi on 17 th April and remained until 4 th May. A HKBWS boat trip on 27 th April produced the fourth HK record of Great Frigatebird and the following day a flock of seven Bee-eaters at Shuen Wan contained at least three and were probably all Bluethroated. The last good bird for April was a first-summer Red Phalarope found at Nam Chung on 27 th April which remained until 4th May. Spring wader passage was very high for the second successive year, with a peak of 15,113 on 19 th April, just short of the record count of 15,149 in The count of 9,012 Curlew Sandpipers was again very high, but Red-necked Stints failed to maintain their recovery in 2007 and were disappointing at only 733. Of the critical three, Asian Dowitcher (NT) had an excellent year with 428 birds (132 in 2007), Nordmann s Greenshank (EN) had an average year with an estimate of 26 birds (50 in 2007) but Spoon-billed Sandpiper (CE) fell back again with only two birds recorded (seven in 2007). Short-tailed Shearwaters put in their now regular appearance in waters off Po Toi, from 30 th April to 24 th May with a peak of 15 on 15 th May. Another Fairy Pitta appeared on Po Toi on 3 rd May, which meant there were two species of pitta on the island on that day. But bird of the month was yet another first, a stunning juvenile White-tailed Tropicbird seen from a HKBWS Boat Trip in southern waters on 4 th May

38 Hong Kong Bird Report : Annual Summaries May brought several latest or unexpected records, an Eastern Buzzard on 10 th on Po Toi, a first ever spring record for Amur Falcon at Kam Tin on 19 th and 20 th, two Asian House Martins on Po Toi on 20 th and an adult Black-legged Kittiwake photographed off Po Toi on 22 nd May. But the most exciting event, caused by a strong depression, was a large fall of small bitterns and Brown Shrikes that started on 21 st May, when a total of 104 Yellow Bitterns were seen at various locations. On Po Toi on 21 st, in addition to the Yellow Bitterns, there was a total of 27 Von Schrenck s Bitterns including a single flock of 22 birds, two Cinnamon Bitterns, eight Black Bitterns, a Malayan Night Heron and 89 Brown Shrikes. High numbers of most of these species were also recorded at other sites on this and subsequent days. Summer 2008 (June to August) June and July were very wet with more than twice the normal level of rainfall. August was drier, although with two Tropical Storms, Kammuri on 6 th and Nuri on 22 nd. Total egret nest counts showed a decline to 668, the lowest since 2000, with all species affected but particularly the commonest, Great and Little Egret and Chinese Pond Heron. The cold weather in February was thought to have been partially responsible. Interesting July records included the first ever summer Dollarbird, an adult on Po Toi on 3 rd, a Black Bittern at Hung Hom on 4 th, an unusual urban location and possibly left over from the late May fall of bitterns, a Black-winged Kite and a Pheasant-tailed Jacana at MPNR from 8 th and a Watercock at Lok Ma Chau on 20 th. Two Eurasian Eagle Owls were seen in July, one at Tsing Ma Bridge on 18 th and one at Kowloon Peak on 23 rd. A juvenile Lesser Frigatebird photographed at Yau Tong on 26 th was an interesting summer record for this species. Eurasian Hoopoes were near Tsing Yi and on Po Toi on 29 th and at Lai Chi Kok Park on 1 st August. The first Aleutian Terns appeared in southern waters on 15 th August, the same date as the first Eastern Crowned Warblers were seen in Tai Po Kau, with an Asian and a Japanese Paradise Flycatcher there on 20 th. A juvenile Hodgson s Hawk Cuckoo seen with a female Hainan Blue Flycatcher at Tai Po Kau on 24 th was the latest ever record for the species. Autumn 2008 (September to November) Autumn was unusually warm, with record high average temperatures in October and very few spells of the northerly winds that normally bring birds to HK. As a consequence, it was generally a poor autumn although the run of HK first records continued with another two in October and one in December. Tropical Storm Hagupit on 23 rd September was the fourth to affect HK in

39 Hong Kong Bird Report : Annual Summaries September was very quiet. Two Goodson s Leaf Warblers, one on Po Toi on 5 th and one at Tai Po Kau on 12 th were the first ever September records for this species. A second HK record of Wedge-tailed Shearwater was photographed in eastern waters on 27 th September following TS Hagupit. October will be remembered by many for two new species and one new subspecies to Hong Kong, all of which were identified from photographs posted on the website. The first was a first-winter Red-backed Shrike found at Ho Man Tin on 6 th, which stayed until 9 th ensuring that many people were able to see it. Less obliging was a Willow Warbler photographed at Long Valley on 25 th but unfortunately only seen by the photographer. In between these two, a male Blue-and-white Flycatcher of the taxon cumatilis was photographed by several people on Po Toi on 19 th October. This distinctive taxon is poorly known but is thought to breed in central China. Another one-day bird identified from photographs on the website was a first-winter Greater White-fronted Goose at Nam Sang Wai on 10 th November, the third record for Hong Kong. Unusual buntings on show in November were a Black-headed at Long Valley from 16 th to 18 th, a Japanese Yellow on Po Toi on 16 th (a rare autumn record) and three Yellow-browed on Po Toi on 27 th. Winter 2008 (December) The unusually warm autumn continued into December, with temperatures above average for most of the month. A Common Chiffchaff trapped at MPNR on 2 nd December was the fifth HK record and the first since A Waxwing on Po Toi on 7 th could not be seen well enough to be identified to species, nor was it relocated, as frustrating no doubt for the observer as for the rest of us. A Little Stint from the Mai Po boardwalk on 13 th was the first ever winter record, as was an Eastern Crowned Warbler at Tai Po Kau on 24 th, while a Chinese Leaf Warbler at Pak Sha O on 28 th December was just the third HK record. The final act of 2008 was, in fact, a postscript. A photograph of a juvenile eagle taken at MPNR on 22 nd December was posted to the website in March 2009, when it was identified as a Steppe Eagle, another first for Hong Kong. Fortunately, it was relocated and seen by many in late March/April An extraordinary end to two extraordinary years
