Can't really point to a single clearly diagnostic feature, but rather a series of things: the bill while far too heavy for Eastern Marsh Harrier, does not appear heavy enough for Imperial, there's something about the head that doesn't look right for most Aquila eagles (I think it's the rather rounded crown and the absence of prominent gape flanges - yellow skin along the mouth). Also the ratios of primary projection over exposed tertials and winglength to tail length favour the relatively longer, narrower winged and longer tailed Bonelli's. Finally the thing that first said "Bonelli's" to me - a really subjective "jizz" thing, but even at rest this bird looks too dynamic for Imperial. Bonelli's must be easily the most dynamic large raptor we have in HK - a real "hawk-eagle".   Mike Turnbull Logged KK Hui BBS Member BBS God Bird Photography - at its best ...     Posts: 940 Re: Eastern Marsh Harrier « Reply #4 on: Nov 28th, 2003, 8:59am » Quote Modify Why didn't I think of Bonelli's Eagle in the first place?!     I would go with your id come to think of it, Mike! As I recall it was definitely smaller than an Imperial Eagle and is of similar size to a Balck Kite ...     KK Hui ARPS www.geocities.com/kkhui_001 Logged KK Hui BBS Member BBS God Bird Photography - at its best ...     Posts: 940 Bonelli's Eagle 白腹山鵰 Juvenile « Reply #5 on: Jan 9th, 2004, 9:54pm » Quote Modify Bonelli's Eagle 白腹山鵰 Mai Po Nature Reserve 米埔自然保護區 09/1/2004 EOS-10D, EF600/4L + EF1.4x Evaluative @ -1/3, ISO 200 http://img5.photobucket.com/albums/v22/kkhui/Avian/090104_25x.jpg   Just to complete the picture with an inflight shot of a Bonelli's Eagle showing its top wings ...     KK Hui ARPS www.geocities.com/kkhui_001 « Last Edit: May 11th, 2004, 12:37pm by BBS Moderators » 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 »
