There is never a dull day at Slimbridge! Even when you see the typical common stuff, you get such great views of them that you can really appreciate them for what they are. A Rook for instance is recognised by most people as 'just a crow' but they are really great birds! They are very different from their urban cousins and specialise on probing into the ground with their long bald bills to cache their food so that they can return later. They are more like Jay's than Jackdaws and Carrion Crows in that sense.
