I will receive these buttons (25 mm wide) in a couple of days. They are 30 nok each, two for 50 nok. Every penny goes to WWF. They will also be sold at the Redlist-show at Fineart in April. Read more about the decline in bird population, threatened species and the Redlist here and here.
Finally some happy news: Farmers in England are saving birds and boosting bird populations by planting plots of seed-rich plants!
