Leucistic bird seen at bird feeders at Durham Wildlife Trust's Rainton Meadows Reserve
No interactions present.
I think the beak looks better for a Reed Bunting or Yellowhammer, perhaps.

Immediate thought was Yellowhammer - at full size image the bird's got the bunting 'sneer' from the angle of the cutting edge on the bill. Seems more Yellowhammer than Reed, somehow.
