Breeding birds in Long Valley: need help for record 記錄塱原繁殖雀鳥

踏入繁殖季節，塱原管理項目亦展開繁殖雀鳥調查，以記錄在塱原繁殖和在繁殖期使用到塱原的雀鳥。由於資源有限，我們未能頻密地到塱原進行調查，為能夠搜集最多的數據，如果鳥友和攝影者到在塱原有發現雀鳥繁殖的行為 (見下列條件)，請記下該雀鳥品種、數量和觀察到的繁殖行為，如有相片記錄更佳，然後以電郵方式通知楊小姐 (yvicky@hkbws.org.hk)。
請注意，為避免影響雀鳥繁殖，請勿接近繁殖中的雀鳥和幼鳥，如發現巢和鳥蛋，請即離開，然後從遠處(約相隔一塊農田)拍下鳥巢大約位置的照片以作記錄，如見到親鳥走回鳥巢，亦請記下鳥種。另外，亦請各位不要公開鳥巢位置，在繁殖季過後歡迎公佈有關照片。

有關在塱原觀鳥和攝鳥時需注意的事項，請參考: http://www.hkbws.org.hk/BBS/view ... &extra=page%3D1

雀鳥繁殖行為 (跟據1993-1996年進行的香港繁殖鳥類調查 [香港鳥類名錄第44-89頁]):
- 明顯的地域性驅趕行為
- 求愛、展示或成鳥因保護幼鳥或鳥巢而發出焦慮的叫聲及激動的行為
- 成鳥視察有機會築巢的地點
- 築巢
- 分散注意力的展示或假裝受傷
- 用過的鳥巢
- 剛孵化的幼鳥
- 成鳥帶著食物或糞囊
- 成鳥恆常往返同一地點，顯示有使用中的鳥巢
- 巢中有鳥蛋或有雀鳥坐著而不願離開或鳥巢附近有蛋殼
- 巢中有幼鳥或有絨毛的水鴨、水鳥和其他剛孵出便立即離巢的鳥種

如有任何問題，請與香港觀鳥會楊小姐聯絡。

Since the breeding season began, we have started conducting breeding bird survey in Long Valley in order to record bird species that breeds in Long Valley as well as those which utilize the site during breeding. Due to limited resources, we cannot conduct survey very frequently. To fill up the data gap, if bird watchers and photographers found any bird with breeding behaviour (see the list below) in Long Valley, please mark down the bird species, number of birds seen, breeding behaviour(s) observed and took a photo if possible and then email to Miss Vicky Yeung (yvicky@hkbws.org.hk).

Please note that to avoid negative impact to breeding birds, please DO NOT approach breeding birds and juveniles. If nest or eggs found, please leave immediately. Take a photo on the nest location in a far distance (about the distance of a farmland). If adult bird is observed visiting the nest, please mark down the species. In addition, please DO NOT disclose the location of any bird nest. All photos are welcome to post to the forum after the breeding season.

Important note for bird watching and photographing in Long Valley, please visit: http://www.hkbws.org.hk/BBS/view ... &extra=page%3D1

Breeding Behaviour (base on the Hong Kong Breeding Bird Survey 1993-1996 [Pg 44-89 of Avifauna of Hong Kong])
- Bird apparently holding territory.
- Courtship, display or anxiety call and agitated behaviour of adult indicating presence of young or nest.
- Adult visiting probable nest-site.
- Nest-building (including excavating nest hole).
- Distraction display or injury-feigning.
- Used nest found.
- Recently fledged young.
- Adult carrying fecal sac or food.
- Adult entering or leaving nest-site in circumstances indicating occupied nest (including colonies).
- Nest with eggs found, or bird sitting but not disturbed, or eggshells found near nest.
- Nest with young or downy young of ducks, gamebirds, waders and other nidifugous species.

For enquiry, please contact Miss Vicky Yeung.

補充一點: 對於觀察鳥巢，請盡量縮短觀察的時間，亦請盡量低調，避免被其他人發現巢位，增加鳥巢遭人為干擾的機會。同時亦不應干擾巢位附近的植物，以免巢位洩露或導致親鳥棄巢。

One more notice: For observing bird nest, in order not to disclose the nest location, please shorten the observation time and keep in low profile. At the same time, DO NOT remove or disturb the vegetation around the nest.

There seems to be less species breeding in LV this year. So far the number of species that are breeding is only about half of that is it last year. Is it true that there are less bird breeding, or the breeding behaviors are more difficult to observe this year? Please help.
