Peregrine Falcon at Reading University

This morning I saw what I am fairly sure was a peregrine falcon (Falco peregrinus) at Reading University. It was making small looping flights from the top of the east side of the Animal and Microbial Science Building.  Underneath (which is alll I saw of it) it appeared mostly whiteish with a black head but this was from a distance.  When It landed back on the top of the building there were various calls which suggests it has a nest there.  When I next go to the university I will be taking my camera and binoculars with me.

I went up again the following weekend but there was no sign of any falcons.  Maybe they were just checking out a possible nesting site and decided against it.
