So the new tiercel’s been making a huge display of territory and the falcon’s been receptive but about ready to be done with the planning stage of the season and lay those eggs, when suddenly today one can only guess the previous peregrine decided he really was serious about getting his nest and his mate back.

Unless it was a third male altogether.

It’s been over a century since there were enough of them alive to bother to fight over a good territory–and there’s nobody alive but all of us to be able to tell what it’s like when they do.

This video shows both camera views at once: same spot, different angles. The one on the right, a UCSC student is trying to figure out where they went, and the fixed-position one on the left, way up in the sky, shows part of the comeback attempt with Grace looking on and yelling Go Team Go!

But at this point nobody’s quite sure who won.
