Last evening I saw a bird sitting on one of the corner's of the building they nested on in 2010. He/She sat there for quite a while.
Really? Hmmm, the 2010 building is still off-limits because of construction/repairs but it is good to know they haven't forgotten their best location ...
On Saturday close to 10:15 A.M., I was driving north on Kenaston approaching the St. James bridge. I saw a bird doing short circles. It landed on a light standard and sat tall and proud. As I drove under it, I certainly saw a peregrine.

Sadly I only glanced briefly, safety first. In agreement with msdolittle, I do not see any sign of construction at their 2010 site.
