The AdW Little Gull reported in Cardiff Bay yesterday was still present this morning until around midday. Difficult to find as it wasn’t doing much flying when I was there. Scanned back & fore with the scope for around 20 mins. then suddenly with the scope stationary it flew into view [viewing from the barrage sails]. For the short while it was in flight it was incessantly chased by a 1st yr Black-headed Gull until forced to land on the water again. Unless it’s flying, v diff to pick up with just binos.
