Clapp, R. Dec. 1963 or Jan. 1964 Sand Midway - Eastern Island Went down to the over-run area in the afternoon. Spent same time watching a small feeding flock of shorebirds. (3 Dunlin, 1 Golden Plover (not feeding)) about 15 Ruddy Turnstone, and 2-3 Sanderling) Ruddy turnstone feed predominantly on the grassy areas near the water; Sanderling in the more pebbly ground and at the edge of the water; and Dunlin in the grass with the turnstone. The feeding movements of each are distinctive. Sanderling make many relatively widely spaced "surface probes" moving from point to point in their feeding area. Turnstone are somewhat similar except that they seem to probe the ground deeper and more strike more frequently at the same area. Dunlin, as might be expected with their longer bills; probe deepest of all, sometimes apparently "worrying" their bills into the ground - 2 Green-winged teal seen on grass at edge of long over-run pond at edge nearest to ocean -
