What are the 1st from left and the 2nd from right? Please help to identify.

I think that Common Tern needs to be ruled out........   dave diskin Logged 深藍 Owen BBS Administrator LOVE KINGFISHER~!     Gender: Posts: 1358 Re: Tern in Mai Po « Reply #7 on: Jun 3rd, 2006, 8:58pm » Quote Modify Will a bigger version help? I ID it as common tern at the begining but after reading Allen post I start query as the date of photo is so close but we got both wiskered tern and common tern report in Mai Po pond 16/7 that few days.   Logged ___________________ http://www.i-owen.com 香港昆蟲網 http://hkinsect.net/forum David_Diskin BBS Member BBS Senior Member I love bird watching!     Posts: 89 Re: Tern in Mai Po « Reply #8 on: Jun 3rd, 2006, 9:20pm » Quote Modify Owen -   To me these are Common Terns.     If you compare Allen's photos and yours, the birds look distinctly different.     At this time of year, particularly with changeable weather conditions, there is a fast turnover of birds. So two terns on the Scrape on the 28th will not necessarily be the same two terns on the Scrape on the 30th!!   dave diskin Logged 深藍 Owen BBS Administrator LOVE KINGFISHER~!     Gender: Posts: 1358 Re: Tern in Mai Po « Reply #9 on: Jun 3rd, 2006, 9:31pm » Quote Modify Thanks Dave.

Also they are too pale below for Whiskered.   Mike Turnbull Logged Mike Kilburn Committee Member BBS God     Posts: 334 Re: Tern in Mai Po « Reply #11 on: Jun 4th, 2006, 10:34pm » Quote Modify This is a good record - Common Tern is rare at Mai Po.  However according to the Avifauna of Hong Kong (p279) late spring is a good time to see them there.   Cheers   Mike K Logged Mike Kilburn Vice Chairman Chairman - ConservationCommittee HKBWS Pages: 1  Reply Send Topic Print Forum Jump: ----------------------------- Announcement 簡訊通告 -----------------------------  - Membership Affair 會員事務   - Outings / Activities 戶外活動 / 講座   - Projects 項目計劃   - Crested Bulbul Club 紅耳鵯俱樂部 ----------------------------- Discussion Area 討論區 -----------------------------  - General 一般問題   - Conservation 自然保育 => Bird Identification 鳥類辨識   - Birding Reports & Tips 觀鳥報告及心得   - Photo Gallery 相片分享 I   - Photo Gallery 相片分享 II ----------------------------- Special Topics 特別主題 -----------------------------  - Wild Birds & Avian Flu 野鳥與禽流感   - Sustainable Management Scheme in Long Valley 塱原可持續生態管理計劃   - Black-faced Spoonbill 黑臉琵鷺   - Goodbye Penfold 告別彭福   - Tern Conservation 燕鷗保育   - Black-eared Kite 鳶(麻鷹)   - Swifts and Swallows 燕與雨燕   - China Birdwatching Network 中國觀鳥活動網絡   - Winter Altas Survey 冬季鳥類普查   - Nature Conservation Policy 自然保育政策 ----------------------------- Knowledge Sharing 知識分享 -----------------------------  - FAQ 常見問題   - Archive 資料重溫 « Previous topic | Next topic »
