As their usual waterways freeze over and temperatures plummet, many birds are forced to move to find open water and places to feed. Though it’s certainly not pleasant for the birds, one of the huge pluses for those who love birding is that, in places like Cardiff Bay, having several days in a row of freezing temperatures can bring in the rarities. And, that’s exactly what happened today, with not one but four Goldeneyes present, a pair that I didn’t manage to see and these two females. I spent a delightful half hour watching them diving and preening and sailing back and forth just outside the iced-up waters along the Barrage. Magic!
