Wild Birds
Traditionally all the images are taken in the 12 months since the last calendar was created. However, this year I included 2 photos from the previous year - so that I could include a couple of UK subjects (no UK trip in 2015).
At least a few images share some kind of theme: "Bath time" for two months. "Confusing names" for three months. Robins and Blackbirds - the American Robin is closely related to the European Blackbird. The sparrow-sized Robin is not related to the American Robin - got it?
