Ducks come in various size and shapes, and so do these miniatures. The smallest ones would be at home with halflings (the apprentice is 18mm to top of head) while some ducks grow tall indeed in the wilderness (Blackfeather the Wood Duck Barbarian is 30mm to top of head). The minis comes on plinths or integral bases instead of slottabases, which adds about a millimeter or two to the total height. In the pictures below they are glued on 25mm round bases (bases not included).
The figures are supplied unpainted and without base
