I took some photos (poor quality sorry) of a bird I saw and assumed the bird to be a Pied Wheatear (1st Autumn). This would be a lifer for me. However I subsquently learned that Eastern Black-eared Wheatear 1st Autumn is extremely similar. For this reason there is a bit of doubt in my mind. Please can anyone advise me in this regard if possible; not just to say what species the bird is but to suggest which features are involved.
