These are never easy to report and this one is particularly difficult. Just a few days before expected hatch, one egg at the Catalina West End nest has been broken. There was evidence of a fully formed chick inside the egg. While no one knows what happened, in watching video, there are some who believe that perhaps first-time eagle mom K-91 accidentally stepped on the egg after being startled. There is one remaining egg and we will all hope for a successful hatch. Tonight Dad eagle Superman has night duty on the nest, which has not been unusual during incubation.
