We have really learnt a lot from this trip. There are also two other external features separating it from Oriental Reed Warbler: 1. Oriental Reed Warbler has black tip in upper and lower mandible. Thick-billed has no black tip in its bill 2. When singing, oriental reed warbler shows red color inside its mouth   The vegetation that these 3 birds stay are also different.   For the spring song, they may sound similar(ga-ga-gee-gee-ga-ga-gee-gee....) but with the following difference: Black browed - higher pitch and more rhythmic Oriental Great Reed - lower pitch and course Thick-billed - slower beat and shorter   Another photo of Black-browed to share: « Last Edit: Jun 7th, 2006, 9:08pm by Uncle_Tall » 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 »
