Although Martin C beat me to it by a couple of days, I was just enjoying my first Red-throated Diver of the autumn at Borth when a Bottlenose Dolphin emerged right in front of it, obscuring my view. Scene stealer.
Not a bad variety offshore: at least two Guillemots and three Razorbills, 20+ male Common Scoters, a Shag, the odd close Manxie and a few Gannets and a dozen or so Sandwich Terns feeding up and down the coast. Oh and six Ringed Plovers flew past.
Dave Purdon came along and stayed for a chat: he'd just had a male Marsh Harrier over the bog.
I had started at Aber where 41 Turnstones were roosting on the sea wall. Then to Ynyslas where apart from a few of the usual waders I could only find a Whimbrel and around 30 Sandwich Tetns. One of the tern posts provided a perch for a Wheatear.
