Once the rain finally pushed away and the NW winds brought clearer conditions with some bright sunny spells, the adult NORTHERN GREY SHRIKE seen yesterday by Richard Broughton and I SW of Hillesden (Buckinghamshire) reappeared mid afternoon. It was again in the same area of farmland, favouring the cut hedgerows and old isolated Oak stumps east of Manor Farm, easily accessed from the muddy footpath leading 500 yards SW of Hillesden church
Park in the new car park adjacent to the church in Church End and take the track across the middle of the crop field down to the wooden bridge over the brook. Cross the next field and then view from just beyond the stile in the next field. The bird is typically wide-ranging but just check the hedgerows and trees, particularly to your left
