How to distinguish wood/geen sandpiper in the field?         Logged Mike Kilburn Committee Member BBS God     Posts: 334 Re: Wood? Green Sandpiper?  白腰草鷸？林鷸？ « Reply #1 on: Apr 18th, 2005, 4:25pm » Quote Modify This is a Green Sandpiper in summer plumage.   Unfortunately the pix in the Guide to the Birds of Hong Kong and South China are not toohelpful for these 2 species.   It is the summer plumage which is harder to seperate Green Sand from Wood Sand, as Green shows more spotting on the wings and back and neck in summer plumage - making it look closer to Wood Sand.     However ther are always some differences:     Green Sandpiper is longer, shorter-legged and holds its body more horizontal than Wood Sandpiper which has longer legs and usually stands more upright.   Wood Sandpiper usually shows a supercilium, - as you can see Green Sandpiper usually does not.   In flight Green sandpiper looks black with a a bright white rump and belly.  The contrast between the dark wings and the white parts of the plumage is very strong.   Wood Sandpiper does not show the same black/white contrast as Green Sandpiper - it usually looks greyish brown in flight,although beoth species have a white rump it is not so clear on Wood Sandpiper.   Cheers   Mike K Logged Mike Kilburn Vice Chairman Chairman - ConservationCommittee HKBWS me_domchan BBS Administrator I love bird watching!     Gender: Posts: 501 Re: Wood?

Wood Sand is a lighter brown bird with larger white and black spots on the wings and back. These pictures offers a good comparison of these features.   It also helps to learn the calls of each species and remember the differences when in flight.   These two pictures also show that Wood Sand often looks longer-necked than Green Sand - Green = hunched and horizontal posture, Wood = a more upright long-necked posture.   Hope this helps     Mike K Logged Mike Kilburn Vice Chairman Chairman - ConservationCommittee HKBWS raycheng BBS Member BBS God I love bird watching!     Posts: 154 Re: Wood?
