Waldschnepfe
The 'pin feather' of the Eurasian woodcock (the covert feather of the outermost primary) can be used as a fine paintbrush for miniatures, or as a delicate tool for moving tiny objects (e.g. specks of dust). As a painting tool, the feather has been described as "far from ideal, holding very little paint, resisting water and wearing down quickly at the tip." The Eurasian woodcock has been the subject of postage stamps from several countries.
