新鸟种——灰岩柳莺的命名

年末新发现---灰岩柳莺

29-12-2009

Named Limestone Leaf-warbler Phylloscopus calciatilis, the new species is very similar to Sulphur-breasted Warbler P. ricketti, in morphology, but it is smaller with a proportionately larger bill and rounder wing. Its song and calls are diagnostic. Based on mitochondrial and nuclear DNA, the new species is most closely related to P. ricketti and Yellow-vented Warbler P. cantator.

Initially, the bird was identified as a Sulphur-breasted Warbler, in itself an interesting finding, since it was apparently breeding more than 1,000 km south of its previously known breeding areas in China. Later it was realised that its songs differed markedly from the songs of the Sulphur-breasted warbler, and further studies were undertaken. The BirdLife and Institute of Ecology and Biological Resources authors provided proof that the species was a resident breeding species in the karst limestone region of central Vietnam. The type description of the species is published in the latest issue of the Ibis, the international journal of avian science published by the British Ornithologists Union.

"The karst limestone regions of Laos and Vietnam are noted for their levels of plant, invertebrate and mammal diversity. It is however, only relatively recently that its importance for bird diversity has begun to be appreciated", said Eames.

There are large areas of forested karst within the known range of the species and it is known to occur in Hin Namno National Protected Area in Laos and Phong Nha-Ke Bang National Park in Vietnam. Although the species is not believed to be under any immediate threat the conservation status of this taxon will be assessed in due course by the BirdLife Taxonomic Working Group; BirdLife will then evaluate its extinction risk category for the IUCN Red List (for which BirdLife is the official Red List Authority).

请转问熊猫大人，他起的名字。

我不認識他，還請Simba兄或其他認識的鳥友代問。

细想也觉得“灰岩柳莺”的名字有问题，很容易被误解为灰色的在岩石生境出现的柳莺。也许“石灰石柳莺”或“喀斯特柳莺”比较恰当。

又再同时出击了。熊猫看到了没有，能给反嘴鹬/鸻解释吗(avocet在台湾的名字是反嘴鸻）

哈，avocet在台灣是習慣叫做反嘴鴴。但以「鴴嘴短」、「鷸嘴長」這樣的大原則來區分的話，的確應該叫做反嘴鷸才是。

灰岩鹪鹛的名字在先。

那正好，也把這誤導人的名字改了吧。
