This Mediterranean Gull was found near the Severn Estuary where Peregrines use nearby industrial buildings.
The corpse showed evidence that can be attributed to a Peregrine kill - no doubt the dead bird then got blown or dropped on to the ground and into the bushes where it was found. Definitely an unusual prey species in the UK but probably more common in parts of souther England and mainland Europe where Med Gulls are found in greater numbers. On the Severn Estuary Med Gulls are found just when passing though on migration. This was an adult in summer plumage.
