Oh I'm still sad about little SE13. But thank you for posting the preliminary report about the necropsy findings so far. I will be interested to find out if the extra testing will prove the cause of death to be the suspected illness caused by a parasite. It was also interesting to find out that the egg that didn't hatch was a fertilized egg, but I wonder why that embryo didn't develop. So much to learn about these incredible raptors. Hopefully, Mum and Dad will have better success next nesting. They seem like a devoted pair and very good parents.
