An Arctic Tern has been feeding in Cardiff Bay today. First seen at around 8:30 this morning by Peter Howlett on his regular round of the Bay, I wasn’t able to go until early afternoon. I set my scope up by Plas Taliesin by Penarth Marina and after some scanning soon picked it up flying back & forth more or less mid bay, looking towards the Taff road bridge. It continued to fly back & forth in that general area all the time and was still present when I left at 2:30. The House Martins from the nests in the Penarth Marina apartment complex were very busy feeding over the water. On my way back I came across the smart male Grey Wagtail below on the concrete wall at the opening of the entrance into the Penarth Marina locks. When it few off it was joined by another.
