A Delft blue mug with ear, featuring a painted blue tit resting on a twig. Or well, resting... The Blue Tit is well known for its acrobatic behavior, with the energetic bird searching for food in all (im)possible positions. Whether that's dangling upside down from a twig or glued to the wall! Its bright beady eyes are always on edge, but its song is described as a silver laugh. A Dutch woodland bird to cherish.
