As my previous post was so short I am posting another cover sent from Switzerland. Thank you Vural for it.  The stamps are cancelled with Geuensee's pictorial postmark. The bird stamp was issued in 1970.
Great spotted woodpecker (Dendrocopos major) can be found in northern Asia and in Europe.  It has many subspecies.  It feeds mostly on insects and grubs but when these can't be found, it can also eat fruit, seeds, small rodents, eggs etc.

Here is another cover fom Ebay.  The stamp, issued in 1969, comes from the first bird set of Cyprus.  It shows European roller (Coracias garrulus) which was shown before in this blog.  The cover was mailed in 1970 and it has a postmark from FPO 201.

Hello everyone,  I am sorry for my long absence but lack of time prevented me from updating my blog.  Moreover, I managed to break my scanner so at the moment I only have very few covers on my laptop that I haven't already uploaded here.

I bought this cover from Ebay.  It was mailed from Taiwan to Colombia.  The stamp was issued in 1983 and it comes from a set of two.

Grey-faced Buzzard (Butastur indicus): It is a bird of prey found in Asia .  It is a medium-sized raptor which preys on large insects, lizards, frogs and small mammals.  This species is migratory.
