Lost Another One!
Jeez, I almost wonder when Helen, the museum female, will quit trying to lay eggs in her lop-sided home. Today, we found another egg splat on the north steps. Mary and I picked up what remained of the shell and stored the shards with the remains of the other 3 eggs.
I asked Mary if she thought Helen would become calcium deficient and she said that she thought not. Four eggs is not any big feat for peregrines and Helen will likely realize that the nest has failed soon and either move to another spot or come back to try again next year.
We take comfort in the idea that the museum pair seems determined to nest on our beautiful building and hope to have some swanky accommodations for them in time for next season.
