Brilliant pics of all the wildlife at your pond Nan. I waited ages to get the pied Kingfisher to flick its fish up like you caught with your kingfisher. I failed, you caught it perfectly.
One of your sandpipers is wrong, the other three are spot on.
Pay attention to the bill size & length, leg size & colour, underparts colour/chest "band" and the back markings. You should be able to figure out which one is incorrect and then look for the right ID for that one.
