Expert: Protected birds' death a mystery
A cull of around 180 bar-headed geese a State second-class endangered animal has baffled wildlife experts. Related Topics
Environment
The dead birds have been discovered at Qinghai Lake over the past week.
Staff with the Qinghai Lake Nature Reserve in Northwest China's Qinghai Province first found 19 dead geese at Bird Island near the western side of the water last Wednesday. Over the following four days larger number of dead geese were found on the island and in nearby areas.
"Initial lab studies have been made and we have ruled out bird flu or other severe infectious diseases," said Li Sandan, director of Qinghai Forestry Bureau.
"The reason of their death is still unknown," Li said.
By Sunday, a total of 178 bar-headed geese were found dead, Li said.
No death reports of other birds, such as brown-headed gulls and cormorants who inhabit the lake have been reported.
"The bar-headed goose migrates high over the Himalayas to spend winter on the Indian plains and breeds in Qinghai-Tibet Plateau in May and June," said Wen Bo, Chinese director of Pacific Environment, a US-based non-government organization which has made efforts to support the growth of Chinese environmental groups for years. "Human activities have greatly changed the living environment of wild birds and affected their breeding activity," added Wen.
Pesticides and hunting are two major factors blamed for the mass death of migrant birds, he said.
Bar-headed geese are hardy birds which have been spotted flying at altitudes of 10,000 metres. Covering 4,232 square kilometres on the Qinghai-Tibet Plateau, Qinghai Lake is China's biggest saltwater lake, with a host of rare, endangered wildlife species including black-necked cranes and wild swans.
Yet in the 1980s, the number of wildlife inhabiting around the lake declined drastically because of illegal hunting and the deteriorating ecological environment.
Local governments in Qinghai have launched a series of environmental protection projects in recent years to improve the living environment of the lake's wildlife.

The cause for 178 Bar-headed geese deaths at Qinghai Lake was found to be H5N1 avian flu. The bird island at the site was temporarily closed from May 5. Other birds in the area, including a large number of Black-headed Gulls, seemed not affected.

青海候鳥染禽流感暴斃 不會飛來本港 疫區全面消毒
【明報專訊】國家農業部昨日宣布，近期青海省剛察縣發現有候鳥暴斃，確診為H5 N1亞型禽流感。經了解證實，這些因禽流感死亡的候鳥，一部分是從東南亞一帶遷 徙而來的。東南亞一帶流行的禽流感病毒與中國流行病毒不同，不僅具有較強的致 病性，還可能含有人的致病基因。疫情發生後，農業部緊急部署，嚴防禽流感擴散 。這是自去年成功消除禽流感疫情以來，中國內地首次宣布發現禽流感疫情。
本港漁護署發言人表示，本港一直有機制監察禽流感和野鳥的情况。世界自然基金 會米埔經理楊路年博士表示，青海沒有候鳥停留香港，本地候鳥來自黑龍江、西伯 利亞和南韓，屬另一飛行路線。他認為只要做足防流感措施，不用過分擔心候鳥會 傳播H5N1病毒。

青海現禽疫 尚未擴散
【本報訊】綜合新華網及《新京報》21日報道：農業部21日宣佈，農業部於5月4 日接到青海省農牧廳報告，青海省剛察縣泉吉鄉年乃索麻村178隻斑頭雁出現異常 死亡。經國家禽流感參考實驗室診斷，確診為H5N1亞型禽流感。目前，已對疫區周 圍以及候鳥遷徙路線所經區域所有易感家禽進行緊急免疫，發生在剛察縣候鳥的疫 情沒有向家禽和人間擴散。
據介紹，從4日至8日，青海湖國家級自然保護區的178隻斑頭雁出現異常死亡。 在提取了死鳥樣本後，青海省林業局對死亡的斑頭雁進行焚燒掩埋，並在5月5日暫 時關閉了鳥島景區，禁止遊客參觀。
據掌握的情況看，青海湖異常死亡的鳥類只有斑頭雁這一種，而鳥島上大量的紅 嘴鷗等都安然無恙。

中國青海一千候鳥死于禽流感病毒
中國農業部表示，截止5月26日，已有超過1000隻候鳥死亡，不過青海省目前尚沒� 酗H被感染禽流感。
最新的死亡數字比官方在周四（26日）公布的519隻多了一倍。
農業部獸醫局局長賈幼陵稱，死亡的候鳥包括斑頭雁、魚鷗等，目前已經採集到了 有關的野生鳥，從它們身上分離病毒，。
有關部門現在正在進行基因序列分析，暫時還沒有找到像南亞一些能夠對人致病的 一些基因。
凡是接觸到候鳥的所有工作者和居民，衛生部門都給予了嚴密監測。
賈幼陵強調，這次青海的候鳥疫情應該不會影響到中國的內地。
未有先例
賈幼陵指出："候鳥帶毒是經常發生的，但是出現這樣大批的死亡，在中國和國際� W都是比較罕見的，以前也沒有聽說過。"
他說，對候鳥禽流感的防控在世界上沒有先例，當局目前採取的一切措施均是防範 禽流感傳染到家禽和人。
政府沿著候鳥可能的棲息地和遷徙路線也進行了調查，也對青海所有的218萬家禽� i行普查，現在沒有發現一例家禽被感染疫情。
農業部5月4日接到青海省農牧廳報告，剛察縣部分候鳥發生死亡，國家禽流感參考 實驗室5月18日從死鳥體內分離到H5N1亞型禽流感病毒。
事發後，青海有關部門封鎖了疫區，禁止遊客及無關人員進入候鳥棲息地和疫區。
