A bird with many names; previously known in the guides as Purple Gallinule, now referred to as Purple Swamphen, and in this case the Purple Chicken - Western Swamphen is its current title as the race of south-west Europe.
The bird was seen immediately before it disappeared for some time, before appearing briefly close in and then flying some distance to the far side of the pool. In between a couple of Bitterns flew around and Marsh Harriers passed over.
