The Great Black Backed Gull is the largest gull in the world and could be flying over your garden any time this winter. The native populations, which still mostly live on the coast the rest of the year, are joined by many visitors from Scandinavia in winter, and many move inland, to Moorland, farmland and dumps. These Gulls harry other, smaller birds, taking them for food (as viewers of Springwatch may have seen), while also eating carrion, food from dumps, eggs, fish and even chips if you are unlucky enough to be walking along the seafront; (Herring Gulls do this too and are more common and likely culprits). Like Herring Gulls and Lesser Black Backed Gulls, they have red spots on the underside of their bills. GBBG’s (as they are known, to avoid the mouth-full of their full name) have white edges to their wings and, unlike Lesser Black Backed Gulls whose legs are yellow, GBBG’s have pink legs. Conditions: A day of gentle thawing at last, with sun and a cool breeze. Temperature: Max 4, Min 0c.
