Bird sighting at Mahon airport (1 Viewer)

Have just returned from a week long holiday in Menorca. Coming home, I saw a bird on a grassy area at Mahon airport that looked very much like a Blue Rock Thrush. Unfortunately, I was on the transfer bus at the time so couldn’t stop and view the bird properly. I’ve seen these birds several times on the island during previous visits, but always on rocky coastlines, so a sighting at the airport seemed unlikely. Does anyone have any thoughts as to whether this is a likely sighting and, if not, what the species might have been? The bird was certainly blackbird sized, blue-grey in colour and “looked right’ for a BRT. Thanks
