似磯鷸多些, 隻雀腹部的白色是否延伸至膊頭位置?
同埋有沒有留意牠有沒有 "un"尾的動作?

Looks like juvenile Common Sandpiper.

I agree with Gary - this is a juvenile Common Sandpiper.

Thanks for the correction from Gary and John!
May I ask what is the characteristic of JV Common Sandpiper?
Thanks for sharing again!

On these photos, the bird looks relatively small (but sometimes difficult to judge on a photo), the tail is long, there is an extension of white in front of the wing on the first photo, and broad white eye-ring. The overall 'jizz' of the bird is just right for Common Sandpiper. The barring on the wing coverts indicate that the bird is a juvenile - adults at this time of year should have plainer wing coverts.

Common Sandpiper is one of the commonest waders in Hong Kong, especially away from the intertidal areas of Deep Bay. It is worth watching these to become familiar with the characteristics of the species, so that you are more easily able to pick up the differences when faced with another species.

John! Thanks for your useful infomation and sharing again!

Let me add a couple of wader comments.
1.Common Sandpipers almost constantly bob their tails.This feature is shared with Spotted Sandpiper which could conceivably occur - but would be easily over looked in juvenile or winter plumage.The long tail projection beyond the wing tips is a feature of Common Sand.
2.Common Sand  has a very distinctive flight- flying close to the water with wings flicking downwards from the horizontal plane, intermittently gliding on bowed wings intermittently.
3.I think Green Sand looks most like Common Sand on the deck.Common Sand have the 'white wedge' near the shoulder breaking into the side of the body as shown here, this is all dark in Green Sand.
4.When looking at waders(as in most birds) try to get some idea of relative proportions , it is useful comparing them with nearby birds.This bird has short legs for its length.Here's a picture of Marsh Sand and Greenshank - highlighting that size and relative proportions matter. You just need to get your eye in.
5.I can recommend 'Shorebirds of the Northern Hemisphere ' by Chandler as an excellent book
