On Friday night September 16th 2011 sighting of a probable Waterthrush from the Lower Moors ISBG hide was made. On September 17th a few birders were there at first light and got brief views of a presumed Northern Waterthrush, which then promptly disappeared. Two local birders went into the wood along side Lower Moors to look for the Waterthrush and found a *Black and White Warbler*, subsequently birders looking for the warbler relocated the Northern Waterthrush in the same area.
The bird was the longest staying Nearctic warbler ever in Britain and was seen until April 16th 2012.
It was filmed by Ashley Fisher on March 22nd 2012.
