If anything the back was more slaty blue than brownish grey.   Also you can see from the forewing that the bird has some hepatic-type feathers - there were also a few (looking rather heavily worn, on the rump), but unfortunately it did not stay around long enough for me to photograph the upperparts.   No migratory cuckoo has ever appeared in August before, but the choices are most likely to be Lesser, Oriental (which has recently been split: Himalayan breeds in Guangdong, and Horsfields much further north in China).  There is also an outside chance of Common following the report of a calling bird in Tai Po Kau this spring. I consider Indian to be highly unlikely.   Any thoughts much appreciated   Many thanks     Mike K   Picture DSCN8981:     Picture DSCN8982:   « Last Edit: Aug 31st, 2005, 9:43am by Koel_Ko » Logged Mike Kilburn Vice Chairman Chairman - ConservationCommittee HKBWS Koel_Ko BBS Member BBS God I love birds!!     Gender: Posts: 222 Re: Mystery cuckoo on Po Toi « Reply #1 on: Aug 30th, 2005, 9:38pm » Quote Modify Just a thought:   In this case I thought this may be a Eurasian, with fine, untidy barring on the underparts, too thin to be expected on Oriental. Lesser seems to have more defined and complete barring.   Reddish iris does suggest Oriental, but Eurasian could have reddish iris as well. The yellow bill base of a rather fine bill suggests Eurasian to me.   As Eurasian widely winters in the Phillipines and South-east Asia I have been baffled by its absence in HK, but I guess some may indeed pass through undetected.   Would love to hear from experts! « Last Edit: Aug 30th, 2005, 10:01pm by Koel_Ko » 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 »
