Flying south early on were a number of Hirundines. A brief sea-watch early recorded good numbers of Common and Sandwich Terns, Gannets heading north, some Teal heading south with a Shoveler and 15 Arctic Skuas.
A small stand of Sycamores held 3 newly arrived and vocal Pied Flycatchers late morning, but unfortunately there was no further coverage of other migrant hotspots at this time. When the area was checked again early evening, there were at least 2 Pied Flycatchers still present and a Common Redstart. Further focus on the sea in the strong easterly in the evening recorded another 12 Arctic Skuas whilst 2 Caspian Gulls and 2 Yellow-legged Gulls were on the beach..
A brief, wind-shortened morning ringing session in East Dunes produced just a new Magpie.

Ideal conditions early on for counting common birds around the dune scrub etc until the heat increased around 0830hrs. A marked decrease of Whitethroats and Sedge Warblers as the breeding birds have dispersed. Only moderate numbers of Willow Warblers after the last influx, but Lesser Whitethroats were in good numbers.
Around 1000hrs the familiar calls of Bee-eater were heard again and the bird was traced to the North Building Ridge (this area was surveyed at 0800hrs when it definitely wasn't there then!). The bird called regularly over the next 30 minutes before circling over the Golf Course and drifting slowly south down the West Dunes. Undoubtedly the individual that has been up and down the Lincolnshire coast over the last week.
Both Pied Flycatcher and Spotted Flycatcher were new arrivals late morning, the juvenile Cuckoo remained in the East Dunes and a Clouded Yellow flew south.
A morning ringing session in East Dunes provided 5 new birds: 2 Reed Warbler, a Sedge Warbler, a Whitethroat and a Robin; and a retrap Dunnock.
The twelfth and final session of CES was done this morning by James Siddle and Ian Thompson. The 10 new birds were a Chiffchaff, a Wren, a Long-tailed Tit, 2 Willow Warbler, 3 Whitethroat, a Lesser Whitethroat and a Great Tit; and the 2 retraps were a Whitethroat and a Blackcap. |

In the dunes were 2 Goldcrests, 2 Cetti's Warbler, a Pied Flycatcher and a Cuckoo. Around was a Marsh Harrier. On Tennyson's Sands were 29 Avocet and 15 Black-tailed Godwits whilst on the Mere there were 3 Green Sandpipers.
A significant arrival of juvenile Gulls along the beach in the evening included 5 Caspian Gulls and 3 Yellow-legged Gulls, also a 2cy Caspian Gull. The feeding flock was busy with terns again offshore and 3 Arctic Skuas involved, with a further 6 Arctic Skuas heading north. Also heading north were single Manx Shearwater and Balearic Shearwater - the latter also seen at Seacroft a short while later after dodging some harassment from an Arctic Skua.
A morning ringing session in East Dunes produced 7 new birds: a Willow Warbler, a Whitethroat, 3 Blackcap and 2 Robin; and 2 retraps: a Whitethroat and a Robin.
