The spots on the wings of the brown birds in photo #3 clearly shows they are juvenile night herons. The one on the left in #2 is moulting into adult plummage.   For #1, juvenile night heron is the only heron I know that is dark brown all over. Chinese pond herons and juveniles should have white bellies and wings.   Little Dolphin Logged Any man's death diminishes me, because I am involved in mankind, and therefore never send to know for whom the bell tolls; it tolls for thee. --- John Donne (1572-1631) Etta BBS Member BBS God I love bird watching!     Posts: 993 Re: What kind of Egret 什麼鷺? « Reply #2 on: Sep 3rd, 2005, 9:33pm » Quote Modify on Sep 3rd, 2005, 11:18am, little_dolphin wrote: Yes, I think the brown birds in all photos are juvenile black-crowned night herons.
