The previous two stamps are from a set, completed by these three. They are all on one sheet, as shown below. Bubo bubo, known as the Eurasian Eagle-owl, is a large owl, with a wingspan of up to 2 metres. The smaller one beside it, Tengmalm’s Owl, is similar in appearance to the Tawny Owl, which is hooting near by our house these days, but has a golden ring in its eyes.
