Stanley Crane appears the grasslands of south part of Africa, with beautiful grey-blueish feather on the back ; Black Crowned Crane lives in west Africa to east Africa, same as Stanley Crane, it is easily can be obverse in grasslands, it also a national bird of Nigeria. Northern Goshawk wildly can be found in North America, most part of Eurasia, perhaps include Korea Peninsular and Herring Gull are very common in offshore of Pacific and Atlantic Ocean.

Unfortunately, the cover sent before day of issue and arrival postmark is cancelled on 6 days before the day. Anyway it still a beautiful first day cover.
