Bulgaria Post issued a set of owl stamps during its stamp exhibition held on Sofia, seem owl stamps are quite popular in Europe as there have many countries have been issued on this year. Three owls of this issue have been shown in here before, only Eurasian Pygmy Owl is new. Thanks childish and Ivan sent me two covers, but sorry I only scanned one as they are similar.
Eurasian Pygmy Owl is the smallest owl which can be found in Europe, mostly lives in Northern and Central Europe, and east to Siberia. It normally can have six to seven years live but some owls will be longer.
