Earlier in Feb 2005, a male was photographed at the same spot. First spotted by my birding buddy Yong DingLi, a Singaporean birder. This is probably a subadult or first winter male, because the white wing bar is very narrow and barely visible.
Same "subadult" male photographed on 09 Feb 2005
The faint light olive brow and greenish head and mantle is distinct for this species.
