Asian openbill stork 钳嘴鹳 (Anastomus oscitans) at Jurong Lake on 27 June 2020

钳嘴鹳 (Anastomus oscitans)是一种大型涉禽,主要分布在印度次大陆和东南亚大陆,在印度、斯里兰卡、缅甸和泰国很常见。其区别于其他鹳科鸟类的主要特征是成鸟的下喙有凹陷,喙闭合时有明显的弧形缺口。

以前钳嘴鹳在新加坡是罕见鸟,然而去年12 月成千的钳嘴鹳到访本地,引起媒体和观鸟爱好者争相报道。 钳嘴鹳主要捕食淡水软体动物 (河蚌和田螺类), 带有缺口的喙是撬开这些动物硬壳的利器, 这也是俗名“钳嘴鹳” 的由来。

昨天我们有幸在裕廊湖边观察到一只钳嘴鹳觅食,拍了几段录像分享在这里。

Asia openbill stork is a large wading bird. It is commonly found in India, Sri Lanka, Myanmar and Thailand. The species distinguish feature is the gap between the arched upper mandible and recurved lower mandible. This feature helps it to open freshwater mollusks.

This bird is rare in Singapore, however, there were thousands of this kind of bird appeared in Singapore in Dec 2019. Many birders and media captured hundreds of openbill stroks flying in the sky.

We are lucky to encounter one openbill stork at Jurong Lake Gardens on 27 June 2020, and observed its foraging behaviour, please see the clips below:

钳嘴鹳的主要生境是内陆湿地,稻田, 主要食物包括淡水软体动物, 也会捕食蛙类和昆虫。钳嘴鹳是农业益鸟, 因为它会大量捕食入侵害虫福寿螺。

Openbill stork's habitats include inland wetlands and crop fields. It feeds mainly on mollusks, frogs and insects. It is a beneficial bird because it feeds on invasive pest snail, golden apple snail.

十二月双溪布洛华语导游Mandarin guide walk@SBWR,December(XIV)

折纸活动/Origami
It was drizzling during the bird watching and sunny after the show. The tide was high and lots of migratory birds (egrets, plovers, whimbrel, sandpiper et al.) were resting or feed on the right pond with exposed mudflat. The root systems of mangrove forest were immersed, but we spotted jellyfish swimming. After the walk, we found otters encountered water monitor lizards at the pond near nature gallery.
今天天气总体来讲相当不错,观鸟的时候有一点点毛毛雨。当时潮水很高,很多候鸟(白鹭,鹬,鸻等)都在主观鸟亭右侧的池塘里觅食休息。去红树林木制步道的时候,雨停了,太阳露了半张脸,海风徐徐,非常舒服。高涨的潮水把红树特有的呼吸根系统都淹住了,不过访客朋友下次还可以来感受完全不一样的红树林。今天比较特别的收获是看到了随海水进来的水母,不过没有拍到好照片(这里要非常感谢那位发现水母行踪的小朋友)。游览活动结束后,我们观察到水獭戏弄泽巨蜥,以及弹涂鱼维修独有的小水坑。

行动中的寄居蟹 hermit crab action

这是一段六年前在chek jawa拍的录像。这个贝壳很不起眼,却是小小寄居蟹的家。沙滩上有很多贝壳,漂亮的,抑或丑陋的,还是把它们留在原地,或许有只寄居蟹正在寻找着。

This video was taken six years ago at Chek Jawa when I vistited this fascinating place for the first time.

白鹭的家Night Home of Egrets

归巢的鸟群 Flocks of egrets come back home
这是一处白鹭(主要是牛背鹭)的夜间栖息地,一小丛树木三面环水,远离喧嚣。
下午五点多,有几只白鹭已经回巢,然后有三三两两的飞回来。
六点钟后,几只到几十只的小群体陆续到达,它们贴着湖面飞来,找准位置落下。
大约六点半到七点是回巢的高峰时段,一群群白鹭飞回来,盘旋在空中找空位,那场面很是热闹壮观。
七点以后,天渐渐黑了,有个别“贪吃鬼”姗姗来迟,不时会惊动鸟群。
后来就慢慢安静下来,进入梦乡。
希望来这里赏白鹭的朋友能静静得坐在草地上,看着斜阳和归巢的鸟儿,让这幅美景能无限延续下去。
