At 10am a pair of Rp's and a juv were on the south end of the beach near, but not with, 2 Sanderlings. The Sanderlings flew off when disturbed by man with dog but the Rp's took evasive action with the youngster freezing on command.
I have seen pairs on the shingle ridges in the past in breeding period but never followed up as I'm not a regular visitor to the beach.
Wheatear also there with a gang of Meadow Pipits
