It’s quite unusual for Gadwall to spend time at Cardiff Bay Wetlands Reserve and for them to be so confiding and so consistently in the company of Mallards rather than their own kind, so this little beauty may well be the same bird that visited the reserve back in March 2021.

Yesterday, she was puddling about right next to the boardwalk, which gave me the perfect opportunity to take some comparison shots with a female Mallard: Gadwall images on the left, Mallard on the right. Female ducks can be tricky to tell apart but you can see here that the differences in their body shapes are quite distinctive.
