I talked to Bob on Thursday evening and he told me he was downtown and had seen a bird on the east side of COB, a juvenile, and it took off flying east of State Street. That is interesting, possibly they are hanging out on the cathedral. He also said he saw the two adults fly in around dark and land on the two bank buildings on either side of Main and South Temple. Here is a follow up note he sent to me
Follow-up report to conversation with Liz on August 18 at 8:16 p.m., or so: angled malar tips suggest that the young-of-the-bird observed on the east rail above the plexiglass on the tall Church Office Building was Charlie.
Later, 8:59 -9:08 p.m., I observed a young-of-the-year bird at roost on the lower right-hand corner of the 6th from the top, fire escape opening on the west side, north face of the tall Church Office Building.
Also, despite repeated calls and messages to return my calls, I've received no word from my contact at the Intermountain Medical Center as to a check/look into the nest box where a few of us have spotted a single adult on the large sign visible on the east face from State Street.
