MERGANSER is a crossword duck, comes to mind quickly when you see the duck word, although I have no idea what a merganser looks like.
I knew about SAD having spent time in Sweden in the winter, and from my son who lives north of Aberdeen. Daylight starvation is not good for you.
For me, it’ll remain just a crossword duck.

Enjoyed 16d, learned a new duck at 9a, and apparently forgot about it in between last week and today. A friend of mine suffers from SAD and is certainly none too happy at the moment. At least we’ve passed the solstice now.

I’ll put this down to a brain fade -was it the former leader of the Green Party who used that expression?
An enjoyable puzzle nevertheless.
A happy new year to all and get well soon Bolton Wanderer.
I’m feeling rather elated after Preston North End’s last gasp win at Cardiff last night. Not a spectacle for the uncommitted. David
And I’ve got to agree with David about the “Mina” spelling. Can that really be correct? I’ve only ever seen it spelled ‘Mynah’, and acknowledge that the ‘h’ is often dropped. But… Mina?
