Stamperija is publishing details of issues bearing the BirdPex8 logo featuring rare birds of some of its client nations. While I have abandoned listing Stamperija's output, this series is a commendable initiative, and is sure to result in the appearance of species of bird that have never previously appeared on stamps.
I will list here, in no particular order, those that I have found so far. The format is the familiar sheet of 4 stamps and a souvenir sheet.
