The Stork may not have the best of credentials but it is certainly well travelled, where photographed the white and black markings along the wing show this to be the same bird. The question is where was it before the first sighting?
This bird does not appear to be the one that was in Lincs/Yorks last year which had different markings a tatty wing and a ring.
