Seven species of owl can be seen on this 2015 stamp and label from the Czech Republic. The main species, the Eurasian Eagle-Owl (Bubo bubo), has been shown a number of times in the past and so has been the Eurasian pigmy owl (Glaucidium passerinum) next to it. Last in the row is the Eurasian Scops Owl (Otus scops), also shown before. It the row below, we start with the ural owl (Strix uralensis), for which I have written earlier today. Following it, is the great grey owl (Strix nebulosa) shown before on a cover from Belarus. Finally, the barn owl (Tyto alba) and the long-eared owl (Asio otus) have been presented on stamps from Belgium and a cover from Switzerland respectively.

This beautiful stamp issued in 2011 shows a black grouse (formely Tetrao tetrix, currently Lyrurus tetrix). It is native to areas of Europe and Asia. It has six subspecies. It feeds on plant material. Finally, it is a game bird in various regions.

The mute swan (Cygnus olor) stamp to the right was issued in 2022. This species can be found in areas of Europe and Asia and it has been introduced to North America and Oceania. Mute swans feed on plants, insects, fish and frogs. They are very territorial. In 1984 the species became the national bird of Denmark.

To the left, a stamp issued in 2008 shows a pair of white-tailed eagles (Haliaeetus albicilla). The species has been presented in the past.

This sheet arrived today from Czech Republic inside the above cover. The sheet was issued in 2010 while the bird stamp on the cover is a part of a similar sheet issued in 2007. I have already written about Common Roller, Wallcreeper and Eurasian Hoopoe.

It feeds on mouse-sized mammals, small birds, lizards, frogs, bats, invertebrates and insects. It has eleven subspecies.
