Will Dr. Sharpe or anyone go up to the nest and retrieve the bodies to try to determine the cause of death?

No, we won't be retrieving the carcasses. By the time we could have reached the nest (2 days for me) I don't think there would have been much left. Also, a necropsy rarely determines the cause of death for our birds.

Thank you, Dr. Sharpe, for your thoughtful and informative answers on this sad happening.

I noted in the observations - and that probably wasn't the right place for it - that a number of loons have been found dead, 10 reported in one day last week, on Ventura Beaches - and 5 ailing ones came into the SB Wildlife Care Network on Saturday (I am a volunteer there.) This is an unusually high number and perhaps there is some contaminant in the water that would affect them - and also gulls ... and perhaps in the gull that was caught by the parent eagles. No way of knowing, but I note the possibility.

No, there hasn't -- and we (June, at the SBWCN) haven't seen any signs of domoic acid poisoning. She did get in a loon on Saturday that was VERY aggressive, vicious, even, if you can say that about a bird, really unusually aggressive, attacking cloth and bedding, hands, and June wondered, but I've seen no indication and no mentions. ...Of course, that doesn't mean there isn't any, since the number of loons coming in and descriptions of them being found quite high up on the beaches is truly unusual.

in 2007 an egg broke before hatching - a 2nd egg did hatch later but that young eagle, died in an accident after it had fledged

2008 - both eggs hatched but the young eaglets were attacked while in the nest by another eagle - after medical treatment, they were hacked/released to fledge, back on SC but one did not make survive.

10 & 26 are young eagles and it is expected that they will try again next year.

I don't have time to google a full explanation, river, but I think red tide is a common name for a type of algae that's unhealthy for humans and possibly small eaglets. I know parts of the coast of Maine (where I live) are periodically closed for clamming and related shellfish gathering due to red tide - and eating a clam or muscle that has been affected is a really bad idea.
