Can you give any details on the ringed GWE please? And was it a breeding adult or non breeding (ie black or yellow bill)?

Some mud exposed this morning. It has attracted 2 Glossy Ibis and 2 Lapwing today but otherwise still dominated by Ducks. Also seen one ringed GWE, a Peregrine, a Sparrowhawk rounding up a flock of House Martins and a Marsh Harrier.
