This female was very young last year, and typically young peregrine females will lay eggs that are not viable. Even with adult females, one of four eggs not viable is not unusual.

There will be two nestlings banded at the May 9th banding event. Last year, one chick hatched for a total of three young produced at the nest over two years. This female was very young last year, and typically young peregrine females will lay eggs that are not viable. Even with adult females, one of four eggs not viable is not unusual. So there is reason for optimism in the sense that this pair has doubled the number of nestlings this year and as she matures, this female should produce eggs with a greater hatch success rate. The unhatched eggs in the nest will be added to the eggs from last year's nesting season and submitted for testing.

So the odds are getting better! Thanks for remembering, Linder!
