– it use to be found only Northeast (Perlis) of Peninsular Malaysia but recently also found a pair breeding at slight south (Penang)

– 铜翅水雉(学名:Metopidius indicus)雉鸻科铜翅水雉属的一种物种,是小型涉禽,体长28-31厘米。头颈、下体黑色,具金属色辉。从眼到颈有白色纵纹,背、内侧初级一飞羽橄榄铜绿色,尾下覆羽栗色。跗蹠的前后均有盾状鳞,趾、爪均甚长,后爪特别长。栖息于热带开阔的田坝区,单个或成对在沼泽湿地中活动觅食。捕食昆虫、蜗牛、小鱼和水生植物。配偶为一雌多雄制,雌鸟常常拥有很多个雄鸟。雄鸟的领域性极强,常常为保卫领域而彼此争斗。7-8月产卵,巢用杂草铺垫而成,每窝产卵4枚。
栖息于富有挺水植物或飘浮植物的淡水湖泊、水库和水塘中,有时也出现于湿草地和水稻田中。留鸟,白天活动,大多单独活动,非繁殖期也常集成小群。行动轻巧而灵活。主要吃昆虫和蜗牛等软体动物,以及水生植物的叶和芽等。分布于印度、缅甸、泰国、越南、马来半岛、印度尼西亚和中国。

101. African Jacana, 非洲雉鸻, 長腳雉鴴, Actophilornis africanus, アフリカレンカク

A distinctive chestnut, white, and black waterbird with a sky-blue bill and enormous feet. The immature lacks the blue bill and shield and is brown-headed. Resident and nomadic, this species trots on the surface of water lilies and other aquatic vegetation, using its long legs and ludicrously elongated toes to prevent it from sinking. It flies weakly, low over the water, with legs and toes dangling behind awkwardly, and calls with a honking repeated “kyaaan” and wheezy hurried “skreeeeeet’–most often in flight. Highly unusual mating system in which one dominant female maintains a harem of multiple males. After egg-laying, each male will raise a brood alone. [EBird]

一种独特的水鸟,体色为栗色、白色和黑色,拥有天蓝色的喙和巨大的脚掌。未成年个体没有蓝色的喙和头盾,头部呈棕色。此鸟为留鸟或游荡性鸟类,常在睡莲等水生植物的表面行走,利用其长腿和极其延长的脚趾防止下沉。飞行能力较弱,通常低空掠过水面,腿和脚趾尴尬地垂在身后。叫声为反复的“kyaaan”号角声和急促的喘息声“skreeeeeet”,大多在飞行时发出。其繁殖系统极为特殊:一只占优势的雌鸟维持着由多只雄鸟组成的“后宫”。雌鸟产卵后,每只雄鸟会独自抚养一窝幼鸟。

update 202501

Here’s another true story of why I prefer using large-capacity memory cards (I’m currently using the Angelbird 1TB CFexpress B). After 18 days of birding, I returned to Malaysia and started editing my photos. That’s when I realized an entire set of pictures was missing—specifically, a series of shots of a bird in flight (it had been flying around us, and I’d managed to capture several sequences).

I checked my SSD, thinking I might have accidentally deleted the folder after downloading, but I couldn’t find anything. As a last resort, I decided to recover the images from the card. Thanks to the large capacity of the card, I had never filled it up completely, which meant the missing files were still recoverable. In the end, I managed to recover the entire series of bird-in-flight shots, as well as some photos of White Rhinos. This experience reinforced the importance of using high-capacity cards!

这又是一个我为什么选择大容量存储卡的真实故事(我目前使用的是 Angelbird 1TB CFexpress B)。在经过18天的观鸟后,我回到马来西亚开始编辑照片时,发现一整组照片不见了——特别是一只鸟飞行的系列照片(当时这只鸟在我们周围飞翔,我拍下了几组飞行镜头)。

我检查了我的SSD,想着可能是在下载后不小心删除了文件夹,但还是找不到。最后的办法是尝试从存储卡中恢复照片。幸运的是,由于卡的容量很大,我从未将它完全填满,所以丢失的文件还可以恢复。最终,我成功从其中一张卡中恢复了这组鸟类飞行的照片,以及一些白犀牛的照片。这次经历让我更加深刻地认识到使用大容量存储卡的重要性!
