Same as before, stamps are designed in small format, perhaps this reason and the huge quantity of print, the stamps not valuable in market. But the birds appear on this cover are very popular and famous in Switzerland or European countries, most of European countries have been issued stamps related to these species.
After counted this cover, I still owe 6 bird stamps which Switzerland issued, either in mint, used or in other formats. Seem it is a good record.

About bird covers : As near the end of the year, most of items are finished and only few covers are waiting for post. Situation of some covers now are waiting return back from remote countries and I guess them shall not come back very soon. Therefore it is time to slow down the update of this blog, but it is not end.Goldfinch (金翅雀) ; Eurasian Jay (松鴉)

To have more attractive of the cover and avoid damage, I suggest use C6 or B6 size envelope to arrange the cover, of course it is not must. If there do not have enough space or the stamps not related to birds, it is better to frank them on back side if post office allowed.
