第2521期:Slender-billed curlew not seen for 30 years

The slender-billed curlew is a shorebird. It breeds in Western Siberia before migrating to the Mediterranean in winter. But there's not been a confirmed sighting since February 1995, when it was spotted in Morocco.细嘴杓鹬是一种滨鸟。这种鸟在西伯利亚西部繁殖，然后迁徙到地中海过冬。但自从 1995 年 2 月在摩洛哥被观察到以来，再也没有对细嘴杓鹬的确认目击报告。Extensive efforts across decades to find evidence of the bird in its breeding and non-breeding ranges have all proved unsuccessful. Its disappearance is a stark warning of the need to tackle the loss and degradation of inland grassland and wetland.几十年来，大量试图在它们的繁殖和非繁殖活动区域内寻找细嘴杓鹬踪迹的努力都以失败告终。细嘴杓鹬的消失对我们是一个严厉的警告，我们必须设法对内陆湿地和草原的退化和消失采取应对措施。词汇表shorebird 滨鸟，生活在海滨的鸟类migrating 迁徙confirmed sighting （对某个生物的）确认目击extensive 大量的，广泛的evidence 证据，踪迹breeding 繁殖ranges 范围，区域proved unsuccessful （某事）以失败告终stark warning 严厉的警告degradation 退化，劣化grassland 草原wetland 湿地
