I climbed Beau Geste last weekend (14th Jan), since it had been a while since it had built a nest there (I had seen the note posted in the toilet blocks last October, and the chicks would have left the nest by now). I was surprised though when I heard the falcon complaining loudly. After a few minutes I saw that it wasn't me it was complaining about; an adult falcon was trying to chase off a smaller falcon off the Watchtower faces. It completely ignored climbers.
