麻鳽是英国叫声最响亮的鸟。这种鸟几乎两度从英国消失不见，但现在其数量正在恢复。英国皇家鸟类保护协会（The Royal Society for the Protection of Birds）的报告说，2021年统计有228只雄性麻鳽 ，是 “破纪录的一年”，与2019年的209只相比有所增加。

 

The boom of a male bittern doesn’t come from his voice box. Unlike other birds, he uses muscles around his windpipe to expand his entire gullet into an echo chamber¹.

雄麻鳽的叫声并非来自它的喉头。与其它鸟类不同，它利用气管周围的肌肉将整个食道扩张成一个回音室。

 

Scientists count them by listening for those foghorn-like booms that can be heard from three miles (5km) away. There were estimated to be just 11 males remaining in the UK in the 1990s.

科学家们通过聆听从三英里（五公里）外传来的、雾角般的低鸣声来统计麻鳽的数量。据估计，在上世纪90年代的时候，英国只剩下11只雄麻鳽。

 

Thanks to systematic² restoration and re-creation of wetlands that were previously³ drained for agriculture, 228 males were counted in 2021.

在对曾为农耕而被排干的湿地进行了系统的修复和再造后，在2021年，雄麻鳽的数量共有228只。

 

Experts say that wetlands are one of the UK’s rare conservation success stories, and that other birds, including cranes, spoonbills and egrets, have returned to sites they’d previously vanished from.

专家表示，湿地保护是英国为数不多的自然保护成功案例之一，其它鸟类，包括鹤、琵鹭和白鹭，也已重现于之前消失的地方。
