Gulls are tricky – I’m sure I’ve said/written that on here before – so, when I heard that a 1st winter Caspian gull (Larus cachinnans) had been seen in Cardiff Bay, I enjoyed seeing other birders’ photos but didn’t for a moment consider going to see it. This was partly because it was only appearing at dusk, when it would fly in to spend the night with the other roosting gulls, and so I wouldn’t have time to see it and then walk home before it was fully dark, but mostly because I knew I wouldn’t be able to identify it even if I did go. So, imagine my amazement when, during a walk around Cardiff Bay on Monday, I bumped into my birding friend Graham, who was watching the Caspian gull, floating on the water only a hundred metres or so off the footpath, in the middle of the day. This was a lifer for me, so to say I was pleased would be something of an understatement!
