Dear Friends,
相信爾兜從來毋識看過「細蒼鷺」。The
Little Blue Heron is a close relative of the snowy egret( 白鷺鷥）. It
looks like snowy when it is young but molts to a dark slate-blue plumage
as an adult. They are only found in North and South American coasts.
Check the photos taken at North Point State Park swamp, near Baltimore,
Maryland last week to see what I mean.
美洲細蒼鷺(little blue heron)
從小到大得人惜（小=細）
羽毛雪白變深藍
成長中脱毛（molting)
白色慢慢變灰白
最後完全變藍色
Compared to great blue heron, little blue heron is smaller and little. This is probably why ornithologist(鳥類學家）call them “little blue“.
