M Johnston 1948 Sandpiper 3 14 Aug can't. 2030 The tide was now coming in - had reached the upper level of the focus zone! These same birds were doing the same that was des- cribed. They flew off shore about a hundred feet then came back & alighted in about the same place on the beach. In flying they will sometimes give a glide then a few quick wing beats then a glide. This specially just before landing.
