I like birds 
Some Russian postcards (actually it's not exactly clear what they are):

Not sure of the source, but I found it here. For all non bird lovers (like me), here's a little guide:
Top two: зарянка (zaryanka) is a robin and probably comes from the word sunrise (заря); мухоловка (mukalovka) is a flycatcher. It can also mean a Venus fly trap plant
Middle two: иволга (ivolga) is an oriole and поползень (popolzen') is a nuthatch
Bottom two: коноплянка (konaplyanka) is a linnet and дубровник (dubrovnik) is a Croatian seaside town and I have no idea! Suggestions on a postcard.

dubrovnik probably has something to do with dub (oak)
hope life's treating you well, anna xx
