Thanks to Richard Hatch reporting a singing Grasshopper Warbler on the SOS website I visited the field north of the wader pool last night but had no joy.
However at 7.30 this morning I made a successful return visit, located the song and even had a visual of this skulking bird! It made a brief appearance on a stunted hawthorn but within about 20 seconds flew into dense cover...not even time for a record shot! It called very spasmodically but with patience I am certain it would show again. On the pool nearby 4 Green Sandpipers still present and 4 Teal overflew Breech Pool.
A perfect summer morning, not a breath of wind, warm and absolutely ideal conditions for Gropper listening!
