The 2020 Stamp Programme for Finland was announced by Posti on 17 October 2019.
From the Posti press release published on 17 October 2019:
The return of migratory birds is a sure sign of spring. The stamps to be issued in March feature four migratory birds that are familiar to Finns: the Eurasian skylark, the common chaffinch, the white wagtail and the barn swallow. In the miniature sheet, the corresponding parts of an old poem that predicts the arrival of migratory birds and the coming of spring have been added for each bird. The stamps, which were designed by Oona Himanen, are simultaneously modern and nostalgic. The Birds from a Spring Poem stamp booklet contains four different domestic no-value indicator stamp designs.
