"All nature sings..."

All nature sings.

I hope these oh so fragile bits of robin's egg shell mean that there will be another robin singing in the front yard. They were too thin even to pick up no matter how gently I tried...so I can't help wondering if, instead, they are the remains of squirrel lunch.

I am always awed by the delicate curves and colour of robins' eggs, even when they're in fragments.
