I will post the bird stamps inherited from both fathers in chronological order. Japanese bush warbler, one of bird series stamps, issued on February 10, 1964. Since this stamp was issued in February, there are no singing warblers, but it has a traditional (?) plum blossoms and the warbler composition. In fact, Japanese white-eyes often come to plum blossoms, but I have never seen Japanese bush warblers come to plum blossoms. I took pictures of the warbler in various places. Shiretoko Five Lakes, Asagiri high land, Lake Yamanaka, Jason Park on the Sagami River near my house.
