A new bird has joined the collection every year since 1972. The bird of the year 2016 – the Harvest Puffball – is inspired by autumnal grain fields. The Harvest Puffball is the two-toned big sister to Oiva Toikka's small, much-loved puffball series of single-coloured birds. The base colour of the bird is opal white, which is coated in translucent brown. The bird's transparent head is framed by a lustre ruff and beak.
