About These Birds

Grey Crowned Crane

灰冕鹤（约3.5公斤）是一种壮观的非洲鹤类，具有独特的金色冠羽和红白相间的面部斑纹。栖息于撒哈拉以南非洲的湿地、草地和农田，常在浅水区觅食。易危；因湿地排水、捕捉用于宠物贸易及农业扩张而面临威胁。

Their elaborate unison call and dancing displays have inspired art and folklore for millennia. The resident population on Hokkaido, Japan, recovered from about 33 birds in 1952 to over 1,800 today.
