I like this cover from Belgium..... there are many bird stamps.... all different ones. 1c is common nightingale, 5c is Eurasian teal, 6c is little owl, 10c is boreal owl and 23c is Eurasian jackdaw. Belgium postal authority has been issuing many fine bird stamps. The other stamp on the cover is Europa issue of 2006 on topic of scouting. The cover was hand stamped on 18 September 2007.
