靚相護燕鷗 齊齊「不登島」Protect terns, do not set foot on Tern Islands

靚相護燕鷗 齊齊「不登島」Protect terns, do not set foot on Tern Islands

各位朋友:

每年夏天,燕鷗都會到本港外圍的一些小島繁殖。
燕鷗有優美的外形、敏捷的身手,
而且通常在開闊的海上出沒,比較容易觀察和拍攝,
因此很自然地成為熱門的拍攝對象,
不少網上攝影論壇都有牠們的照片。

燕鷗的繁殖地非常敏感,容易受人干擾,
如果有人登上燕鷗島,會嚇走親鳥,
令鳥蛋和雛鳥失去護蔭,在烈日之下曝曬而死。
受驚的雛鳥會到處亂竄,可能因此跌傷或溺斃,
者甚至給登島的人踏死。

人們登上燕鷗島,會嚴重影響燕鷗繁殖,
不單觸犯了《保護野生動物條例》,
更壞的是開立了先例,吸引其他人有樣學樣,
為燕鷗島帶來災難,最後可能會令燕鷗不再來。

為了宣揚「不登島、免干擾」的守則,
熱心會員 James 和多位會友設計了一個「不登島」印記(見下圖),用來放在照片上。

印記的作用有三:

一. 以身作則,聲明作品並非在島上拍攝
二. 提醒大家不要登上燕鷗島,干擾燕鷗繁殖
三. 提供有力例證,示範不用登島也可以拍得精彩的照片

各位可按這裡:「不登島」印記 下載印記的 Photoshop 檔案。

歡迎將印記加在以繁殖燕鷗或其生態為題的照片中,
支持和宣揚「不登島、免干擾」守則,
讓公眾在欣賞之餘也收到保育生態的訊息,
為保護本港的燕鷗出一分力!


謝謝!

Dear friends,

Every summer, three species of terns come to breed at a few small outlying islands in Hong Kong.  Graceful, agile, and easily seen over open waters, terns are among the most popular subjects for bird photography.  Pictures of terns can be found in many photo forums both local and overseas.

However, tern breeding colonies are very vulnerable to disturbance.  Adult birds would flee once photographers set foot on these colonies, leaving their chicks and eggs on the island to be fried by the hot sun.  Chicks running around in panic may suffer falls, got drown or even stepped on by people.

Landing on tern islands will bring serious disturbance to the birds and can be prosecuted under the Wildlife Protection Ordinance.  Worse still, the act may draw other people to the site, bringing disaster to the colony.

To raise public awareness of the “Don’t disturb, don’t land” code, HKBWS members James and others have produced a “No landing” (in Chinese) icon in the attached photo. By putting the icon on a photo, we can

1.  declare that the work was taken without setting foot on the island
2.  reminder people against landing on tern colonies
3.  demonstrates that high quality pictures can be taken off the island

The photoshop file for the icon can be downloaded from here: Logo_layer.

You are welcome to show it on your pictures.  This will help to spread the code and keep the terns coming every year.

Thank you!

謝謝各位支持!

為表謝意,已在此貼出照片的朋友(包括 ckuifai),
將獲邀參加 7 月 22 日的燕鷗調查活動,
詳情會另行個別通知。

齊齊「不登島」,燕鷗年年好。

Thanks for your great support!

As a token of our thanks, those who have already posted here (including ckuifai) would be invited to the tern survey to be held on 22 July.  Details will be notified individually.

In case some people are still not convinced, here are some extracts from the web reporting how human disturbance has led to breeding failure.

如果有人還不相信登島可破壞燕鷗繁殖,以下是一些從網上找到的例子。

1. BirdWatch Ireland – Roseate Tern
http://www.birdweb.net/tern.html

One worrying development happened late in July when all the remaining colony of birds deserted the rock apart from two pairs of birds which were nesting on the left side of the rock. This desertion was unprecedented in the nine years of the project and there was a strong suspicion that the birds might have been disturbed by human presence.

2. BioOne - Black-naped and Roseate Terns
http://www.bioone.org/perlserv/? ... SOTSLO%5D2.0.CO%3B2

The recent increase in the frequency of visits to islets by people from Noumea (ca.100,000 inhabitants), resulting from the increase in the number of leisure boats, may be the principal factor responsible for the current trends and threats. Human disturbance seems to be a major threat that may lead to desertion of seabirds on islets, or reduced breeding success.


3. Bird life of Pulau Layang Layang - Black-naped Tern
http://www.tracc.org.my/Borneocoast/LAYANG_LAYANG/pll_birds.html

Unsuccessful breeding seemed to be due primarily to disturbance in the form of inquisitive visitors (tourists from the resort and Navy personnel), predation by cats and the twice daily flights which flew directly over the breeding colonies.


4. Tampa Bay Soundings, USA – Bridled, Caspian, Royal, Sandwich, Roseate, Least, Sooty, Brown Noddy
http://www.baysoundings.com/sum02/birds.html

But by far the most important cause of outright nesting failure is disturbance by people. Forcing adults to fly exposes eggs containing delicate embryos to the hot sun and almost certain death. Year after year, repeated human intrusion at nesting colonies has caused steep declines in some populations.

5. Birds in Backyards - Little Tern
http://birdsinbackyards.net/finder/display.cfm?id=254

The Little Tern is extremely sensitive to human disturbance when breeding and is rapidly declining in numbers and range. Nesting sites are usually located where humans swim, walk, exercise dogs, picnic and drive off-road vehicles.The mere presence of people on the beach may cause these terns to desert their eggs and eventually leave the colony altogether.

6. Joint Nature Conservation Committee, UK – Common Tern
http://www.jncc.gov.uk/pdf/UKSPA/UKSPA-A6-90.pdf

Declines in specific colonies in Britain and Ireland, with some complete losses, can mostly be put down to habitat changes, e.g. coastal developments and increased disturbance, especially recreational, although as with all terns birds can desert breeding colonies for behavioural
reasons, resettling again after a period of time.

7. John F. Kennedy Space Center Environmental Program Branch - Least Tern
http://environmental.ksc.nasa.gov/projects/documents/tern_skimmers.pdf

Other factors that are correlated with abandonment are human disturbance, presence of mammalian predators, and flooding. Of these, human disturbance is probably the factor most responsible for recent declines. Human-caused disturbances can exacerbate many of these problems, which increases the rate of turnover and decreases the reproductive success of colonies. The same areas that these birds value for nesting habitat are unfortunately the same areas humans value for recreational activities. Human intrusion along beaches, lakes, and streams reduces the available nesting area for these birds.

8. National Audubon Society, USA - Gull-billed Tern
http://web1.audubon.org/waterbirds/species.php?speciesCode=gulter

Human disturbance from boating, recreation, and development is a primary conservation concern, as it causes the young to disperse from the nest too early, sometimes resulting in heavy losses due to exposure to weather and predators. Where human activities are concentrated on some Atlantic Coast barrier islands, this species has shifted to nesting on marshes and dredge spoil islands.

請勿打擾,又是燕鷗繁殖時
Time to put this on top again.
