A wave of migrants have pushed through during the week. Grasshopper Warblers have been widely reported and Wicken Fen in particular has hosted lots of reelers. A nocturnal safari around the Fen and Washes in the next week could readily pick up whipping Spotted Crakes, booming Bittern, roding Woodcock, reeling Grasshopper Warblers, serenading Nightingales and any number of vocal flyover waders. The first warm and still night we get I'll be out.
