It was wonderful yesterday to see that Goosanders are now returning to Cardiff Bay after their breeding season. I’m not exactly sure where these birds would have spent their busy summer months as, according to recent copies of the Eastern Glamorgan Bird Report, they haven’t been recorded breeding locally for many years.

Goosanders can often be seen in the Bay over the winter and, yesterday, three birds were fishing in the River Ely where it flows in to Cardiff Bay.

There were two females and this handsome bird, which I think is a male in eclipse plumage, i.e. transitioning from summer to winter colours. I took a little video of it preening, if you want to take a look.

(Apologies for the spot in the video – it’s inside my camera, rather than on the lens, but I haven’t been able to take my camera to be cleaned because of our lockdown restrictions.)

294/365 A confusing Goosander

There were actually 5 Goosanders on the River Ely this morning. Four stayed their distance but this one, paddling alone, came over to investigate me.

I’ve been trying to work it out. I don’t think it’s a female – though they have reddish-brown heads, they’re more generally grey in the body, without so much black on their backs.

And it seems that in juvenile Goosanders the separation between the white throat and chin and the brown head is less clear cut, more ragged – in this bird it seems well defined.

So that leaves me with a male bird in eclipse plumage, i.e. still undergoing the change from its breeding plumage (of black-dark green head and upper neck) to its winter plumage, though that would usually be complete by now, I think.

Hence my confusion. If any experienced birders reader this, I would welcome your opinions (and explanations). Thanks!
