A disturbing trend is that mainland species are starting to go extinct, rather than island species: “Ninety percent of bird extinctions in recent centuries have been of species on islands,” said Stuart Butchart, BirdLife’s chief scientist and lead author on the paper.
国际鸟类联盟的首席科学家、论文的第一作者斯图尔特·巴特哈特说,一个令人不安的趋势是大陆物种开始变得比岛屿物种更容易灭绝。他说:“几个世纪以来,百分之九十灭绝的鸟类都是岛屿物种。”
“However, our results confirm that there is a growing wave of extinctions sweeping across the continents, driven mainly by habitat loss and degradation from unsustainable agriculture and logging," he said.
他说:“然而,我们的研究结果证实,日益高涨的灭绝浪潮正席卷整个大陆。主要原因是不可持续的农业和伐木造成(鸟类)栖息地的丧失和退化。”
An additional species of bird – the Spix’s macaw, which was made famous in the 2011 animated movie "Rio" – was declared extinct in the wild. Only a few dozen captive Spix's macaws are alive.
斯派克斯金刚鹦鹉因2011年的动画电影《里约大冒险》而出名,然而,目前野生的斯派克斯金刚鹦鹉已告灭绝,只有几十只被捕获的斯派克斯金刚鹦鹉还活着。
电影《里约大冒险》主角原型
《里约大冒险》的主角是一只稀有的小蓝金刚鹦鹉,它的原型是一只叫做Presley的斯派克斯金刚鹦鹉。2017年,Presley去世了,没有留下任何后代。而当时这种鹦鹉在野外已经很难寻觅了,人工繁殖保护之下,全球也只有不到100只,科学家担心近亲繁殖会让它们的基因产生太多缺陷,最后免不了还是走向灭绝的境地,所以一直在全球寻找野生的小蓝金刚鹦鹉种群。然而经过数年的寻找,人们沮丧地发现,它们可能真的,已经消失了。
