印度尼西亚一名高级分类学家近日表示,最早于1996年在印度尼西亚偏僻的托吉安岛发现的一种鸟实际上是一个鸟类新物种。
根据印度尼西亚科学研究所发表的文章,托吉安暗绿绣眼鸟或称之为索马迪卡塔暗绿绣眼鸟是以分类学家苏卡尔贾·索马迪卡塔的名字命名的。索马迪卡塔的同事穆罕默德·因德拉万1996年最早在印尼中苏拉威西省的三个小岛沿岸发现了这种小鸟。后来他们花了数年时间,与密歇根州立大学著名的亚洲鸟类问题专家帕梅拉·拉斯梅森合作,最终确定这是一个新的物种。
世界自然基金会雅加达办事处提倡保护面临灭绝危险物种的哈伊尔·萨利赫说:“这个新物种不同于白色眼圈的暗绿绣眼鸟。它的眼睛有一圈红色羽毛,而不是白色羽毛,它的喙为深红色。我们仍在研究这个物种的数量,估计为1000只左右。”
索马迪卡塔说,这种鸟非常活跃,以小群行动。它的栖息地不足5000平方公里,“我们认为它正处于灭绝的边缘”。

A New White-Eye (Zosterops) from the Togian Islands, Sulawesi, Indonesia
Mochamad Indrawan, Pamela C. Rasmussen, and Sunarto
We encountered white-eyes (Zosterops) that did not match any known species during ornithological field observations in the Togian Islands, Gulf of Tomini, Sulawesi, Indonesia. Subsequently, we collected a specimen and made tape recordings. We consider the Zosterops of the Togian Islands to be a new species that differs most strikingly from the Black-crowned White-eye (Z. atrifrons) in lacking a white eye ring and in soft-part colors. The new species has a somewhat higher-pitched, less modulated song than Z. atrifrons. It seems uncommon and has been encountered only near sea level on three small islands, and it may be best considered Endangered. This brings the number of endemic species in the Togian Islands to two and, under BirdLife International criteria, this island group (which has recently been declared a National Park) now qualifies as an Endemic Bird Area.
