Hit-and-run WUM
Me and two other Manx birders watched this gull for 'a good while' and are a little perplexed by it. Could it be a Heuglin's? Size-wise it wasn't much, if at all, bigger than a Herring Gull ( I have several more shots of the bird including one of it with a Hering Gull) and the bill hasn't got the depth of a GBB. Nor did it have the sheer 'presence' of a GBB. Perhaps it is only a runt GBB. I should stress that none of the observers (including myself) are great gull fans!
