At approximately 5:00PM I was leaving the MBL parking lot onto Water Street and noticed a strongly built bird flying over the Klimm Dock and surrounding waters approximately 50m distant. I recognized it as a (likely) Peregrine Falcon. I saw it start to double back toward the buildings (MBL Club/Bigelow) so I parked and walked over. Found the bird perched on the ledge of Bigelow. This is the time last year we had one and I wonder if it's the same bird, a year on. Looks more mature.
