The first photo is a Wood Sandpiper and the remainder are Greenshank
Thanks, James. They are definitely all the same bird, though - they were taken within a few seconds of each of before and after it took off. I'm just wondering about marsh sandpiper now, but I don't think the feet project far enough behind in flight.
Two suggestions the standing bird is wood sand - but can't be as I followed the bird with the camera and photographed it on the ground and as it flew. So if the flight photos are greenshank, so is the standing photo. I suspect it may be zooming in on a distant shot which has distorted the original to make it misleading. Thanks for the help, anyway.
Honestly - these are different birds. The flying bird has a pale head, white cigar shaped mark on the back and a long bill. The standing bird has a darker head an neck, is less rangy with a shorter bill and a supercilium and a compact build. I promise they are different birds!

Beach was covered in dry weed. Bird feeding amongst weed then flew off.
