Today (19 March 2020) the Cathedral of Learning falconcam suddenly zoomed in very very closely so right now it looks like this.
I don’t believe it’s fallen down. You can see from this snapshot photo that the nest is just fine. There is not a camera lying in the nest.
I’m not sure who zoomed it. … If they can’t correct it, I hope they call for technical support.
Meanwhile you can see snapshots of the nest at this link. The (zoomed out) snapshot camera is the second of the two photos.
