Regular Cardiff Bay birder Gareth Stamp had an amazing 3 Firecrests together this morning, in scrub & trees near the old Custom House along the Cardiff side of Penarth Head. They had moved on to feed somewhere else by the time I arrived although I did check all the trees up the hill to Paget Terrace. As I walked back to the car park area, a Wren was scolding away from the top of a vertical twig stuck in the rocks of the outer harbour, so I got a few nice portraits.
