I agree it should be Wood Sand.
I missed this post before I asked.

[quote:2525be8477="tmichael"]No, not a Greenshank. As the name suggests, Common Greenshank has green not yellow/orange legs. It looks like the same Wood Sand that was posted a few weeks ago.
Interesting bird to track, if it continues to winter in HK.
