Back home an enforced cycle ride refound the Cuckoo and various moth caterpillars in the ling (plenty for the Cuckoo to eat then). The Shunan was full of water after last night's torrential rain so just a few Dunlin and little else to report.
Then back to Birsay for a look at the Arctic Tern colony, 49 sitting birds at least, a count of the Grey Seals, 43 hauled out with more in the water. A look for the Curlew Sand was unsuccessful, it was low water, although the Sanderling were still easy to see and another wader ??? disappeared into the distance.
