Nest is on top of cell tower near Chestnut Ave. and I664. Today (June 20, 2012), I saw activity in nest, possibly young peregrines, with an adult nearby. This was viewed through binoculars at nearly 1/4 mile away from the 4th story of the Liebherr building. I'll try to take pictures and post them. The adults removed nesting material from our company property for 1-2 months which ended about 1 month ago (a few of us saw them very close to identify). The movement I saw today could have been an adult but it was frequent and spread out which makes me tend to think it my be young ospreys moving about. I'll post updates!
