I know that Scarlet Tanagers use chick-burr as an alarm call, though that may not be the only purpose of that call. Four hours of alarms seems excessive, though I suppose there could've been a hawk or owl snoozing nearby. Last year when the Taughannock peregrines just fledged, they landed pretty close to the trail and allowed fantastic eye-level views. Seems like they had not yet learned to be afraid of humans, and possibly yours was similar. When it flew towards the crow, perhaps it was just a function of the prevailing wind rather than an intentional direction.
