The damp gloom of Tuesday’s walk around part of Cardiff Bay was much improved by the birds, in particular the presence of species that disappear to breed in other parts of the country before returning to spend their winter days in the local area.

One such species is the Goosander, though they’re not yet looking in their best condition. These birds are still in what is called eclipse plumage, where it’s difficult to tell which is male and which is female, as the male birds assume a kind of in-between plumage after they finish breeding and before their full winter plumage grows in. So, the redhead above might be a female but, equally, it might be an eclipse male, whereas the Goosander below is definitely a male.
