四川现“最神秘鸟” 被救四小时后死亡

2016-03-18 15:53:37   中国青年网

广元发现的海南虎斑鳽,已无力站立。

在人类发现它的第四个小时,这只被称为“世界最神秘的鸟”在广元野生动物临时救助中心永远闭上了眼睛。

海南虎斑鳽(“yan”,与“严”读音相同),我国特有珍稀鸟类,被列为国家二级保护动物,世界最濒危的30种鸟类之一,目前全世界仅存1000余只。

在它身体逐渐变得冰凉时,海南虎斑鳽仍双爪紧握,两翼紧闭。

广元河滩边发现4小时后死去葬于凤凰山

3月10日下午1时许,广元市天朝区东溪河乡村民在羊亩河滩边发现一只体长约30厘米的灰色长喙小鸟瘫软颤栗,无法站立。村民随后拾起送到当地林业站,再转送至市上动物临时救助中心,然而无人识得这只小家伙到底属于何种类别的鸟,随后上报省级野保单位。

此时已是下午4时,经检查,它全身并无外伤,而翅膀却不能动弹,双腿无力支撑,脚爪一只拳握,另一只蜷缩身下,垫起身体全部重量。救助中心随即从市场买来小鱼喂食,但它一口不吃。

下午5时许,它本瞪大的眼睛微微闭合,最终永远合上了,葬于广元凤凰山。经四川省市野生动物保护专家鉴定,它是海南虎斑鳽,是我国特有的珍稀鸟类,被列为国家二级保护动物,为世界最濒危的30种鸟类之一,目前全世界仅存1000余只。在此之前,它未被列入四川省鸟类资源图谱,省内属首次发现。

专家介绍,这只海南虎斑鳽并非成年鸟,或在迁徙途中落单。

“世界最神秘的鸟”曾被猜想“已灭绝”

海南虎斑鳽,学名Gorsachiusmagnificus,中型涉禽。它的羽毛是暗褐色,石板灰色的飞羽泛着绿色金属光泽,翅上覆羽间藏少许白色斑点。

几乎无人在野外闻其鸣叫。它喜独处、夜行,人类对它所知甚少。自1899年它在中国海南被发现并命名以来,一百多年间,人类鲜见它的踪迹。上世纪六十年代至九十年代,它是否灭绝的争论曾引起国际关注,“或已灭绝20多年”让它在参评国家保护动物时被定为“二级”。

它不喜鸣叫。不论在栖息地或筑巢地,人类都极难听到海南虎斑鳽的鸣叫,给人一种“神秘”的感觉。据广东省林业网介绍,浙江千岛湖是目前国内发现的最大海南虎斑鳽繁殖地。在它的繁殖期,它非常惧怕人类打扰,一有异常响动,便将脖子伸得老长,警惕地张望着。它的巢和其他鹭科鸟类相似,均以筑巢地周围常见的枯枝搭成浅盘状,每窝卵二至四枚。

海南虎斑鳽是世界上公认的鸟类濒危物种,因第一个模式标本于1899年采自海南岛的五指山而得名。该鸟的形体和大小都近似鹭,嘴长、颈长、脚长,上体黑褐色,并具有白色斑点,眼后有一条白色条纹向后延伸至耳羽上方,以鱼虾、小螺、昆虫为食。虎斑鳽昼伏夜出,从被人发现到失踪,生活习性一直鲜为人知。由于虎斑鳽鸟极为稀少,因而被称之为"神秘鸟"。

1929年,中山大学生物系的师生曾在位于广西自治区中部的金秀大瑶山采集到该鸟的标本,这是广西自治区20世纪90年代以前惟一的纪录。20世纪60年代初期,华南动物考察队曾在海南作过多次调查,时间长达数年,也仅在中部山区采到了两只标本。此后一直再没有关于该鸟踪迹的报道。
