Latvia-1995 Nature Conservation

A nice cover from an exchange I did during June 2012, with a stamp friend in Latvia. Cancelled in Riga, the stamps  were issued in 1995 for the European nature conservation year. The birds: 20s Corn Crake (Crex crex), 8s White backed woodpecker (Dendrocopus leucotos) and 24 s White-winged tern (Chlidonias leucopterus).
   The cover also has a pictorial cancels of  birds which featured on 2011 stamps, the Icterine warbler (Hippolais icterina)  & a  Short-toed Snake Eagle  (Circaetus gallicus )
