Although there is no way to assess the size of the bird from the images, it still looks small and slim like a stint. The bright yellowish legs and bright edges to the upperpart feathers are unlike Pectoral Sand. at this time of year, the bill is a bit too short for Pectoral and although difficult to make out, this bird has apparently very little (if any) primary projection, whereas Pectoral Sand would show an obvious primary projection.   Hope that helps (?)   Ian Logged Anton BBS Member BBS God Watch me if you can~     Gender: Posts: 142 Re: Pls Help!  Pectoral Sandpiper ?! « Reply #2 on: May 1st, 2006, 9:35am » Quote Modify Thanks Ian.   Here is one more photo of this bird...maybe this can give more information about its size...could this further confirms its ID?   Thanks.   Logged macca BBS Member BBS Junior Member     Gender: Posts: 18 , of whichRe: Pls Help!  Pectoral Sandpiper ? « Reply #3 on: May 2nd, 2006, 3:16am » Quote Modify Anton,   yes the size comparrison helps enormously and offers us a definative answer.   The bird on the left is a Wood Sandpiper, of which Pectoral Sandpiper would be a similar body size but with slightly shorter legs. He we can see the bird on the right, the Long-toed Stint, is considerably smaller than the Wood Sandpiper just like it should be as they really are very small (and infact not that much bigger in body size than a Sparrow!)   Best wishes,   Ian Logged Anton BBS Member BBS God Watch me if you can~     Gender: Posts: 142 Re: Pls Help!  Pectoral Sandpiper ?! « Reply #4 on: May 2nd, 2006, 3:17am » Quote Modify Is this bird a juvenile Long-toed Stint?   Logged Mike Kilburn Committee Member BBS God     Posts: 334 Re: Pls Help!  Pectoral Sandpiper ?! « Reply #5 on: May 2nd, 2006, 10:46am » Quote Modify It is an adult.   Juvenile birds appear after the breeding season, not before.   The issue of moulting and what plumages birds show at different times of year is a complex one. But as a rule juvenile plumage refers to the first plumage after fledging (after the fluffy chick stage).     Different birds have different moult strategies, and for some birds such as eagles and gulls this can be very complex, as birds take several years and several variations of plumage to reach full maturity.   As a general rule smaller birds have fewer variations of plumage.  Adult waders have two plumages - breeding (or summer) plumage, and non-breeding (or winter) plumage.     The issue is much more complex than this, but a small wader should go chick, juvenile, first winter, adult (although some will show a first summer plumage (a duller, less distinct version of adult breeding plumage).   Further input from people who really undersand mult would be welcomed.   Cheers   Mike K Logged Mike Kilburn Vice Chairman Chairman - ConservationCommittee HKBWS Anton BBS Member BBS God Watch me if you can~     Gender: Posts: 142 Re: Pls Help!  Pectoral Sandpiper ?! « Reply #6 on: May 4th, 2006, 3:20am » Quote Modify Thanks Mike~~   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 »
