Today, on day 4 of the #7DaysofWildChristmas challenge, my search for the wild took me down to the river – the River Ely, that is – where the river flows in to Cardiff Bay and where the embankment is now edged with tall apartment blocks and where one half of the river is a marina, home to millions of pounds of water craft. It’s a path I walk often but today I was particularly delighted to see my favourite dumpy little waterbirds, the Turnstones, had returned – eleven of them – and they’d brought a friend along, a handsome Redshank that was trying uneasily to snooze while the Turnstones prospected for food to and fro.
