But if the number of the kite is high and/or flying fast, we need to estimate the number by grouping. We normally group it into every 5-20 birds. And then scan how many groups in a time. It is a technical estimation and experience is needed.   All are welcome to join us for the monthly count and we can share the experience and our interest in kite.   Our next count will be on 5th Feb (sunday) 80mins before sunset (around 4.15pm).  For those who are interested in joining, please email me at yankarin@graduate.hku.hk   Karin Chin Kite Research Group Logged raphaelwcs BBS Member BBS Newbie I love bird watching!     Posts: 7 Re: How to count flying kite 請教用什麼方法數鷹 « Reply #2 on: Feb 1st, 2006, 6:56pm » Quote Modify thanks a lot Logged 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 »
