Turning and turning in the widening gyre; the falcon cannot hear the falconer

Missing Dogs Massachusetts is a Facebook page that's normally just what it sounds like. So a posting today is a little unusual, but, then, there aren't many places to look for a missing falcon:

BOLO: Beloved family falcon is missing, last seen Plum Island area. She is very friendly and social and will likely seek out humans by landing on a car or a house, and squawk at them. Still has tether on.
