Linda’s rock in Lake  Ülemiste. Postcard ca 1920s

Last week a notice went through the  newspapers that the Muinsuskaitseamet (Estonian National Heritage Board) had finally granted permission for removal of three ritual rocks that would hinder the expansion of Tallinn Airport. What was startling in the news however was the fact that one 100-tonne sacrificial rock with grooves would be sawn into four parts and transported so to the others.

Goldfinch

Goldfinch    Ohakalind     Carduelis carduelis

The passing of migrants heading towards south usually ends with the end of October but weather and winds also play a part. A couple of ten thousand ”brave” winterers remain depending on the severity of the winter. Breeders in Estonia in summer are estimated at forty to sixty thousand pairs.

The sociable goldfinches move around foraging in small groups and so they can be compared to each other easily.
