Today, April 20, I checked this nest. I found an adult eagle perched atop the nest tree but didn't have time for a photo before he or she flew off.
Meanwhile and afterwards, for the half hour I was in the area, from time to time I heard a soft gulling call coming from the nest itself.
I don't know yet if my photos will show anything but there has to be someone in there, hunkered down below the rim, not sitting upright as on a nest visit.
