Unknown Gulls @ Green Island 不知名銀鷗@青洲

[size=3]Report from SS Group Volunteer!
Some unknown Gulls show up at the sea near Greeen Island during 22-24Feb2010!

報告來自燕子組的義工, 於2月22-24日在青洲對出海面發現一些銀鷗,
觀察者初步估計是"黃腳銀鷗"!(有錯請指正!), 報告詳情如下:


22Feb2010: 19隻下午約4時,由南丫島飛向西環（around 4pm, 19 unknown gulls, fly over the sea from Lamma Island to Sai Wan, Hong Kong Island.）

23Feb2010 : 8-9隻下午約4時30分在青洲向九龍的停泊遠洋船浮泡附近浮游 (around 4:30pm, 8-9 unknown gulls show up at the sea near Green Island)

24Feb2010 : 3-4隻下午約4時30分在青洲向九龍的停泊遠洋船浮泡附近浮游(around 4:30pm, 3-4 unknown gulls show up at the sea near Green Island)

25Feb2010: 看不見了！ (can't see any gull anymore!)[/size]

我也覺得是銀鷗類，若果照片顏色夠準，是黃腳銀鷗！

Heuglin's Gulls usually arrive on the southern sea coasts of Hong Kong in February, sometimes with other species like Black-tailed. The East and West Lamma Channels are popular because they feed off waste thrown overboard from ships. I presume they are coming from all around the Pearl River Delta, having wintered there.

Later they start migrating east and north, passing Po Toi in the afternoons throughout late February and March in flocks of up to 50 birds. See the attached chart for daily records of Heuglin's Gull from Po Toi over the past 5 years.
