The Yellow-legged gull is my bogey bird, one I see reported by much more experienced birders than me but which I always have trouble identifying. So, imagine my delight when this 2cy bird (its age – this is the second calendar year since its birth) was mentioned on our local birders WhatsApp group. I recognised where it was standing and knew another (or the same?) Yellow-legged gull had favoured the same place last year. So, on my next walk around Cardiff Bay, I looked for and found it, and was very pleased to add a late new bird to my patch birding list for 2021, bringing the total to 119, one more than last year (though the mix of birds was different).
