Singing Marsh Warbler

After having seen 16 Crossbill go over our garden calling this morning and checking the valley. I went along with Mo to see the Marsh Warbler at Rainham Marshes, which did not show well while we were there but was still great to hear singing. Like the ones I've seen before and heard for that matter, they are always entertaining to listen to copying other bird calls like Swallow, Quail, Blackbird and Blue Tit. See if you can recognise anyone from the crowd shots?
