I have a box of bird bones and feathers, tiny blue egg shell, dead butterflies, dried tea roses.
There are piles of wishbones and three or four bird skulls with different beak shapes, deep hollow eye sockets.
I think I started collecting these things to use in assemblages. Gorgeous dragonflies and cicadas. Beautiful beetles. Then feathers and the odd hatched or fallen egg.
The first skull came from a birdhouse in my yard. I found it long after the bird got its head stuck somehow and died, half in, half out of the entrance hole.
The wishbones accumulated from many chicken dinners. A hoard of unspent wishes.
