Early in the afternoon, the fledgling was impossible to find.  One of the parents attempted to grab a young sparrow off a nest in a Cathedral window, but then flew off.

After the weather front went through, I went back to the Cathedral to find the fledgling coming off of a high area of St. Luke's roof, towards the Cathedral.  It misjudged the landing and returned to St. Luke's.  It did this about an hour later, attempting to land on the nest, again it misjudged and returned to St. Luke's.  Nature's given the fledgling great innate flying skills, but it seems that instinct doesn't cover landings and this needs to be learned.
