I emailed the panel of eagle experts. One of them suggested looking at whether the nests of other eagles and brown pelicans were also failing in the area. Although DDT contamination is possible, it isn't the only potential factor. If any of you have that information, or know where nest reporting is done for Sauces beyond this cam, please let me know.
I also got asked if this was another trio. I don't watch this nest closely enough. As far as I know, it isn't, but wasn't there an eagle trio in the area at one point?
Thanks!
