Deer Park: Manxies and a Gropper

A walk out on the Deer Park tonight from 2130-2245 gave a wonderful view of Manxies rafting before coming ashore on Skomer. Spread across St Bride's Bay were 15-20 separate rafts of birds. The smallest raft was roughly 500 birds, the 2-3 largest numbered in the thousands. A really calm night like tonight and minimal moon offers a great opportunity to see large numbers of Manxies from the shore here.
Also, a Grasshopper Warbler reeled continuously from the gorse between the Coast Watch station and Wooltack Point. Someone I met had seen (and photo'ed) another reeling Gropper by the old hide at Marloes Mere this morning.
A male Sparrowhawk made an unsuccessful go at some linnets in the valley. I have not seen a Sparrowhawk around here since last winter.
