Back to Arpley tip this morning for our organised gull watch, observer numbers were lower than normal but fortunately that seemed to mirror the gull numbers. Still, a good selection was seen with a juv Glaucous Gull first off that showed well most of the morning together with 2x1w Iceland Gulls, 4 Yellow-legged Gulls, 1w Med Gull and a 3rd winter Gull that superficially looked good for Caspian, it ticked all the boxes but its head didnt fit ? Theres a photo so see what you think. Once we cleared off from Arpley it was over to Richmond Bank and just in time also, within 2 minutes of arriving we had an Adult Iceland Gull then a 1w Iceland Gull and that was it ? A tidal surge up the mersey covered the exposed mud banks and cleared out the gulls. All in all a great days learning, again.
