Every other Tuesday I have been going in to Cambridge on the service bus to my U3A course on Polar Studies at the Scott Polar Institute. As the speaker today was commanded to go to the Economic Forum in Davos, we had a different speaker at short notice: he was very good.
On the way in, I just relax and count the bird species I see. Usually it is between 8 and 12 different species, although in total I have seen many more.

There are some waxwings in Cambridge. These birds come from Scandinavia and are quite rare most winters. I have yet to see one. They are often seen eating berries in supermarket car parks.
