Britain's most spectacular commemoratives, No16: 2000 Above and Beyond 19p

Another of the stunning photographic essays used for the Millennium series, this one takes as its subject the heart-shaped face of the common barn owl.

Owls always seem inscrutable, but this one from the World Owl Trust sanctuary at Muncaster seems to be looking into the lens with complete disdain.

Alternative nicknames for the species, such as ‘demon owl’, ‘ghost owl’ or ‘hobgoblin owl’, seem very apt when you are confronted by such a stare.
