Ui nest Poole Surgery car park p1

Observation - Ui nest Poole Surgery car park p1 - UK and Ireland. Description: Urban. This disused nest suggests to me that of Eurasian Jay, but it is in an isolated tree in a VERY urban location. It appears too bulky for Wood Pigeon, to small for Carrion Crow, and lacks the dome of Common Magpie. Circa 12' above ground. Any other

Any other suggestions please?
