Thanks to Ray Fellows who has been over the Marsh and confirmed that the Garganey is still present this evening but elusive. When not on the open water the bird is tending to retreat into the dense vegetation on the north east side of the main swag pool.
If you decide to go for it I suggest you approach quietly as this is your best chance of finding it on the open water and if its not showing, be prepared to wait quietly until it eventually decides its safe to come out of cover. Don't go around the pool as apart from risking flushing the bird and potentially sending it away it is particularly muddy and you wont do your foot ware any good.
Needless to say in the current conditions sun-screen and water are strongly recommended!
Good luck and happy Friday - Chaz
