漁護署鬥智鬥力趕絕家鴉

【明報專訊】家鴉被視為害鳥,數年前入侵深水埗區滋擾民居,去年至今又有4個家鴉樣本驗出H5N1禽流感病毒,令居民人心惶惶。漁護署自03年重點打擊家鴉繁殖,3年來捕獲和檢獲家鴉及鳥蛋共505隻。負責「趕絕」這群不速之客的漁護署主任坦言,家鴉智商比3歲小孩還要高,對付牠們是長期鬥爭,必須不斷出新招與之鬥智鬥力,如用美食引誘、從雀巢偷蛋「貍貓換太子」,以減低對居民的滋擾及禽流感的風險。

AFCD is starting their campaign against House Crows this year as the birds begin to breed in April.  The department’s actions at Sham Shui Po have already captured 505 birds and eggs since 2003.  Mr WH Lee of AFCD said this would be a long-term engagement, as the birds have higher intelligence than that of 3-year-olds.  Various approaches have been used, including baits with a changing “menu” and planting fake eggs at their nests.  The next step would be a tailor-made trap.



防禽流減滋擾 星洲開槍殺鳥

【明報專訊】深水埗居民擔心家鴉聚集在民居附近會傳播禽流感,H5N1關注組成員兼傳染病專科醫生勞永樂表示,家鴉愛吃雀鳥屍體腐肉,故感染禽流感的風險較高。漁護署濕地及動物護理主任利偉雄指出,為加強預防禽流感,在捕捉家鴉的行動中,該署會把所有檢獲鳥屍體和幼鳥進行H5N1病毒測試,去年至今測試290個樣本,有4個驗出有病毒。

Dr Lo Wing Lok commented that House Crows have a higher risk of catching H5N1 because of their preference for carrion.  Mr Lee explained that all birds and carcass would be tested for the virus, and that 4 positive cases have been found among the 290 samples since last year.
